What is NetFlow?
NetFlow is a network protocol that is used to report information about the traffic on a router,
switch, or other traffic-conducting network device. NetFlow works by collecting and
summarizing the data that is carried over a device, and then transmitting that summary to
another device, called a collector, for storage and analysis.
NetFlow Monitor is a software-based NetFlow collector designed for use on servers running
Microsoft Windows operating systems. After configuring routers, switches, and other devices
to transmit NetFlow summary data to NetFlow Monitor, you can view reports that allow you
to:
ƒ
View network usage trends to determine when to upgrade hardware to increase network
capacity.
ƒ
Recognize and correct network configuration issues that may needlessly consume
network resources or expose your network to security vulnerabilities.
ƒ
Identify traffic which may indicate undesired network usage, such as unauthorized use of
peer-to-peer file sharing applications or a denial-of-service attack against your
organization.
ƒ
Troubleshoot and correct causes of spikes in network traffic before they become
problems.

Using WhatsUp Gold NetFlow Monitor
How does NetFlow Monitor work?
When a router or other device sends NetFlow data to NetFlow Monitor, it follows the process
shown below.
1
The router gathers information about the traffic that is passing through it and
summarizes that data into a NetFlow export.
2 The router sends the NetFlow export to the NetFlow Monitor collector.
3 The NetFlow Monitor collector stores the NetFlow export in the database.
4 When the report data is viewed on the web interface, NetFlow Monitor retrieves the
data from the database and manipulates it to produce the report.
Tip: WhatsUp Gold NetFlow Monitor can collect and generate reports for NetFlow data from
multiple devices.
Supported versions
NetFlow Monitor can receive and interpret data from NetFlow versions 1, 5, and 9.
System requirements
WhatsUp Gold NetFlow Monitor has the same base system requirements
(http://www.whatsupgold.com/wug123relnotes) as WhatsUp Gold v12.3. In addition,
WhatsUp Gold NetFlow Monitor requires:
ƒ
WhatsUp Gold v12.3 Standard Edition, Premium Edition, MSP Edition, or Distributed
Edition
ƒ
At least one routing device that supports NetFlow version 1, 5, or 9
ƒ
SQL Server 2005 Standard or Enterprise Edition (recommended)
Note: WhatsUp Gold NetFlow Monitor is more demanding on the database than WhatsUp
Gold. While WhatsUp Gold NetFlow Monitor can successfully use SQL Server 2005 Express,
we recommend either MS SQL Server 2005 Standard or Enterprise Edition for best
performance.
2
Using WhatsUp Gold NetFlow Monitor
ƒ
An additional 2 to 4 GB RAM recommended
ƒ
16 GB (required) to 22 GB (recommended) hard disk space for the databases

Determining which NetFlow sources to monitor
The information that NetFlow Monitor collects is influenced by the location of the NetFlow
sources relative to firewalls or other devices that perform network address translation (NAT).
In short, the data is dependent on what and how the source sees. Carefully consider which
routers or other NetFlow-enabled devices you want to configure to export flows to NetFlow
Monitor to ensure that you see the type of data that you want to see.
Depending on where the source is located relative to the device performing NAT, traffic to
and from internal (private) IP address are reported differently in the exported NetFlow data.
ƒ
If the source is inside the firewall, or if no firewall exists, the exported NetFlow data
includes the internal IP address for devices generating and receiving traffic. This allows
you to pinpoint the exact device to which the traffic belongs.
ƒ
If the source is outside the firewall, the exported NetFlow data aggregate all traffic to and
from internal devices and report it as belonging to the public address of the device
performing NAT. In this case, you can only determine that an internal device originated or
received traffic, but you cannot pinpoint the traffic as belonging to a specific internal
device.
5
Using WhatsUp Gold NetFlow Monitor
ƒ
When the device exporting NetFlow flows is also performing NAT, you can configure the
device to export the NetFlow data using either the private or the public NAT address,
mimicking either of the above scenarios. To see internal IP addresses, configure the
device to export data on ingress and egress for the internal interface. To see all
traffic reported using the external IP address of the NAT device, configure the device to
export data on ingress and egress for external interfaces. For more information, see
Configuring NetFlow sources (on page 6).
Other conditions may also change the nature of the data reported by NetFlow Monitor.
ƒ
If NAT occurs anywhere in the path between the source and the destination, IP addresses
reported are altered to include the address of the NAT. In most cases, this does not
present a problem, but it may require monitoring multiple NetFlow sources to track traffic
in complex network environments.
ƒ
Virtual private networks and other tunneling technology (such as ESP or SSH) can appear
to distort reports. In these cases, NetFlow Monitor reports large amounts of traffic sent
over a small number of flows. This is expected behavior, as VPNs and other tunnels
aggregate traffic from multiple connections and funnel it through a single connection.
Configuring NetFlow sources
Before you can view meaningful reports, you must configure NetFlow Monitor and NetFlowenabled devices, such as routers or switches, to communicate network activity back to the
NetFlow Monitor listener application.
Configuring NetFlow sources is a three-part process that requires:
1
2
3
Setting up NetFlow Monitor to listen for NetFlow data on the appropriate port.
Configuring NetFlow devices to send NetFlow data to NetFlow Monitor.
Setting options for the NetFlow source in NetFlow Monitor.
To configure NetFlow Monitor to listen for NetFlow data:
Note: By default, NetFlow Monitor listens for NetFlow data on port 9999. If you want to use
that port, you do not need to perform this procedure.

From any workspace view or report in the web interface, select GO. The GO menu
appears.
If the NetFlow section is not visible, click NetFlow. The NetFlow section of the GO menu
appears.
Select Configure > NetFlow Settings. The NetFlow Settings dialog appears.
In Listener port, enter the port number over which NetFlow Monitor should listen for
NetFlow data.
Click OK to save changes.

Using WhatsUp Gold NetFlow Monitor
To configure NetFlow devices to send NetFlow data to NetFlow Monitor:
Caution: This procedure is an example that applies to a Cisco 1812 router and should not be
used for other devices. The process for configuring a device to export NetFlow data varies
widely from device to device and dependent upon your network configuration. Please see
your router's documentation to determine the correct process for your device.
ƒ
ƒ
Step 1. Open the configuration interface for the router and enter the commands detailed
in the following table to configure global options for all interfaces on the router.
Command
Purpose
enable
Enters privileged EXEC mode. Enter your password if
prompted.
configure terminal
Enters configuration mode.
ip flow-export version
<version_number>
Sets the version of the NetFlow protocol that should be
used to export data. NetFlow Monitor supports versions
1, 5, and 9 only.
ip flow-export
destination <IP> <port>
Enables the router to export NetFlow data. Substitute the
NetFlow Monitor server's IP address for <IP> and the
listener port specified in the NetFlow Monitor NetFlow
Settings dialog for <port>.
Step 2. Enter the commands detailed in the following table to enable the router to export
NetFlow data about the traffic on an interface. You must repeat these commands for each
interface.
Command
Purpose
interface <interface>
Enters the configuration mode for the interface you
specify. Substitute <interface> with the interface's name
on the router.
ip flow ingress
Enables NetFlow data export. Select the command that
best fits your needs.
- or -
ƒ
ip flow ingress exports flows of all inbound
traffic that uses the interface.
ƒ
ip flow egress exports flows of all outbound
traffic that uses the interface.
ip flow egress
7
Using WhatsUp Gold NetFlow Monitor
Tip: If the device exporting NetFlow data is also performing network address translation
(NAT), we recommend exporting egress data from the internal interface so that private
network addresses are communicated. Any other configuration results in all private
addresses reporting as the public addresses of the device performing the network address
translation.
Note: Other options exist for configuring NetFlow. For a complete list of available options,
see Configuring NetFlow (http://www.whatsupgold.com/NF_CiscoCfg) on the Cisco Web site.
To configure options for NetFlow sources in NetFlow Monitor:
1 From any workspace view or report in the web interface, select GO. The GO menu
appears.
2 If the NetFlow section is not visible, click NetFlow. The NetFlow section of the GO menu
appears.
3 Select Configure > NetFlow Sources. The NetFlow Sources dialog appears.
4 Select the source from the list, then select Edit. The NetFlow Source dialog appears.
Note: If you cannot locate a source in the list, verify that the source device is set up to export
NetFlow data properly. All devices sending NetFlow data to NetFlow Monitor automatically
appear in the list.
5
In Display Name, enter a friendly name for this NetFlow source. This name is used
throughout NetFlow Monitor to identify this source.
6 Verify that Collect data from this source is selected.
7 Set SNMP options. NetFlow Monitor uses SNMP to query information about the
interfaces on the NetFlow source.
a) Select the appropriate SNMP credentials. If the credentials you want to use are not
included in the list, click the browse button (...) to open the Credentials Library. For
more information on configuring credentials, see Using Credentials in the WhatsUp
Gold User Guide.
b) To set advanced options, such as timeout and number of retries, click Advanced. The
Advanced dialog appears. Set the appropriate values, then click OK to return to the
NetFlow Sources dialog.
c) Select Query to query the router using SNMP to get updated names and speeds for
the available interfaces.
8 Configure the speed of each interface, which is used to calculate capacity as a
percentage of the total interface speed.
a) Select an interface, then click Details. The NetFlow Interface dialog appears.
b) Select Hide this interface from the NetFlow Home page and related configuration
properties to hide the selected interface from the NetFlow Monitor Home page and
other menu options in NetFlow Monitor. This lets you display only the interfaces that
are relevant to your bandwidth monitoring requirements.
c) Select Specify a custom speed for this interface. The In and Out fields are enabled.
8
Using WhatsUp Gold NetFlow Monitor
d) In In and Out, enter the upper limit of the interface in bps (bits per second). Common
interface speeds expressed in bps are:
ƒ
1 Gbps = 1,000,000,000 bps
ƒ
100 Mbps = 100,000,000 bps
ƒ
10 Mbps = 10,000,000 bps
Note: NetFlow Monitor supports NetFlow versions versions 1, 5, and 9 only. If you export
data using other versions of the NetFlow protocol or other protocols that are similar to
NetFlow, such as IPFix or sFlow, NetFlow Monitor discards the data.
After you configure the listener port and set up NetFlow sources, NetFlow Monitor begins
tracking data and generating reports.
Monitoring traffic on non-standard ports
NetFlow Monitor automatically classifies traffic for most common applications. However, in
some cases, you may need to create a custom definition to ensure that NetFlow Monitor
properly classifies some traffic. This need is most common when:
ƒ
Your device routes traffic for applications that use a proprietary protocol. This may be a
custom program that uses a protocol developed in-house to send data across the
network or a third-party application that uses its own custom protocol to transmit data.
ƒ
Your device routes traffic for standard applications over non-standard ports. Examples
include a standard Web server running on a port other than 80 or an FTP client
connecting to an FTP server that runs on a port other than 21.
Note: For traffic to be considered unclassified, both the port that the data is sent from and
the port to which it is received must not be classified in the NetFlow Ports dialog. If either of
those ports are classified, the traffic is associated with the application of the classified port.
To accommodate these cases, you can classify traffic that meets specific rules so that NetFlow
Monitor reports that traffic as belonging to a certain application.
Important: You can configure the amount of time unclassified traffic data is kept. For more
information, see Configuring data roll-up intervals (on page 10).
Tip: If NetFlow Monitor detects a large amount of traffic to an unmonitored port, the Top
Applications workspace displays a yellow warning flag that explains the situation and guides
you in defining the unmonitored port. This can help you to proactively detect emerging nonstandard traffic on your network. You can also use the Unclassified Traffic dialog (available
from any page in NetFlow Monitor by selecting GO > Configure > NetFlow Unclassified
Traffic) to view all unclassified traffic since the last hourly rollup.
9
Using WhatsUp Gold NetFlow Monitor
To define rules for classifying traffic that uses non-standard ports:
1 From any workspace view or report in the web interface, select GO. The GO menu
appears.
2 If the NetFlow section is not visible, click NetFlow. The NetFlow section of the GO menu
appears.
3 Select Configure > NetFlow Ports. The NetFlow Ports dialog appears.
4 Click New to configure a new port definition. The NetFlow Port dialog appears.
5 In Port, enter the port number over which the traffic is sent.
6 In Application, enter a name for the traffic that you are classifying. This should be the
name of the protocol (for instance, the definition for port 80 includes HTTP as the
application).
7 Select Monitor the following protocols on this port, and then select the protocols
that the application uses (TCP, UDP, or SCTP).
8 Click OK to save changes.
Configuring data roll-up intervals
NetFlow Monitor is designed to serve two primary purposes:
ƒ
To give a minute-by-minute view of recent network traffic.
ƒ
To give an overview of historical network traffic.
To accomplish these goals while keeping the size of its database reasonable, NetFlow
Monitor uses a process of summarizing data at certain time intervals.
By default, NetFlow Monitor rolls up data on this schedule:
ƒ
Complete raw data (which is collected every other minute and provides the detailed view
of recent traffic) is kept for 8 hours.
ƒ
After 8 hours, raw data is summarized into hourly averages.
ƒ
After 3 days, hourly averages are summarized into daily averages.
ƒ
After 14 days, daily data is archived.
ƒ
After 93 days, archive data is purged from the archive database.
You can configure the intervals to roll up data more or less frequently depending on your
network's size and traffic volume.
To set data roll up time intervals:
1 From any workspace view or report in the web interface, select GO. The GO menu
appears.
2 If the NetFlow section is not visible, click NetFlow. The NetFlow section of the GO menu
appears.
3 Select Configure > NetFlow Settings. The NetFlow Settings dialog appears.
10
Using WhatsUp Gold NetFlow Monitor
4
Under Report Data, customize the roll up intervals to meet your requirements.
ƒ
Data collection interval. Select how often NetFlow Monitor writes collected data
from its sources to the database. You may select 1, 2, 3, 4, 5, or 10 minutes. By default,
data is written to the database every 2 minutes.
Note: Modifying collection interval settings affects both the granularity you see in NetFlow
Monitor reports. If the interval is set to 5 minutes, you cannot distinguish traffic collected
during the first minute from traffic collected during the fourth minute.
ƒ
Roll up raw data after. Enter the number of days and/or hours after which raw data
collected from your NetFlow devices should be rolled up. This setting determines the
number of hours of raw data that can be reported on at any given time. After data has
been rolled up, NetFlow Monitor can report data usage for each hour, but detailed
granular data (such as bytes, flows, and percentages) is aggregated into a single value
for the entire hour. By default, raw data is rolled up after 8 hours.
Caution: Modifying the roll-up settings directly affects the size of the NetFlow Monitor
databases and the performance of the application. We recommend that you modify these
settings cautiously, monitoring the effects on database size and application performance.
ƒ
Roll up hourly data. Enter the number of days after which hourly data should be
rolled up into daily data. After hourly data is rolled up, NetFlow Monitor can only
report aggregated totals for entire 24-hour blocks of time. By default, hourly data is
rolled up after 3 days.
ƒ
Archive daily data. Enter the number of days after which daily data should be moved
to the archive database. By default, daily data is archived after 14 days.
ƒ
Expire archive data. Enter the number of days after which daily archive should be
purged from the archive database. By default, archive data is purged from the
database after 92 days.
ƒ
Resolve private address interval. When the NetFlow Monitor collector service
encounters an IP address, it tries to determine information about the host attached to
the IP address. After this information is resolved, it is stored in the NetFlow Monitor
database. Enter the interval (in hours) that you want NetFlow Monitor to wait, before
it checks the private IP address again, to resolve information that may have changed
for the address. By default, private addresses are resolved every 48 hours.
ƒ
Resolve public address interval. When the NetFlow Monitor collector service
encounters an IP address, it tries to determine information about the host attached to
the IP address. After this information is resolved, it is stored in the NetFlow Monitor
database. Enter the interval (in hours) that you want NetFlow Monitor to wait, before
it checks the public IP address again, to resolve information that may have changed
on the address. By default, public addresses are resolved every 720 hours.
Tip: Because public IP addresses are less likely to be changed, you may want to use longer
intervals than used for the Resolve private address interval option.
11
Using WhatsUp Gold NetFlow Monitor
ƒ
Expire unclassified traffic after. Enter the number of hours after which NetFlow
Monitor should purge unclassified traffic. Unclassified traffic is traffic transmitting over
ports that are currently not monitored by NetFlow Monitor. By default, unclassified
traffic is expired after 1 hour.
Tip: You can prevent NetFlow Monitor from saving data about unclassified traffic by setting
Expire unclassified traffic after to 0 (zero). When this option is set to 0 (zero), NetFlow
Monitor aggregates and retains data for all unclassified ports as a single value; detailed
information about the individual unclassified ports over which traffic was transmitted is
immediately discarded.

Click OK to save changes.
Important: Any changes made to data roll up intervals are not enforced until the NetFlow
Monitor collector service is restarted. For more information, see Stopping or restarting the
collector (on page 14).

NetFlow Monitor database and archive database.
To access the database utilities:
From the WhatsUp Gold console main menu, select Tools > Database Utilities.
13
Using WhatsUp Gold NetFlow Monitor
Using the database backup and restore backup utility for NetFlow
Monitor
You can back up your complete NetFlow Monitor SQL Server database and archive database
to any mapped directory you have on your network. Database backups are saved as .dat files
and can be restored at any time. Restoring a .dat file overwrites your current database with
the data in a .dat file.
Important: You can use this feature with any local instance of SQL Server whose databases
are named NetFlow and NFArchive. This feature does not work with remote databases.
Important: We strongly suggest that you backup and restore the NetFlow database and
archive database as a set. When you backup the NetFlow database, you should also backup
the archive database. Similarly, when you restore the NetFlow database, you should restore
the archive database to the version that was most recently generated by the NetFlow
database.
If you want to back up the SQL database to a mapped drive, the Logon settings for the SQL
Server (WHATSUP) (or your customized SQL service) must have write access to the mapped
drive.
To change the SQL database logon settings:
1 Click Start > Control Panel > Administrative Tools > Services, then double-click the
SQL Server (WHATSUP) service. The SQL Service Properties dialog appears.
2 Click the Log On tab on the Properties dialog.
3 Change the account logon settings as required.
Note: This is a complete backup and restore, so any change that you make after the backup
will be overwritten and lost after restoring a backup.
To access the Database Utilities Backup and Restore features:
From the main menu in the WhatsUp Gold console, select Tools > Database Utilities > Back
Up NetFlow Current or Archive Database
- or select Tools > Database Utilities > Restore NetFlow Current or Archive Database
Stopping or restarting the collector
You can restart the NetFlow Collector Service through NetFlow Monitor, WhatsUp Gold, and
Windows.
To stop or restart the NetFlow Collector Service through NetFlow Monitor:
1 From any workspace view or report in the web interface, select GO. The GO menu

NetFlow collector. The service restarts.
To stop or restart the NetFlow Collector Service through Windows:
1 Open the Windows Control Panel.
2 Select Administrative Tools > Services. The Services window appears.
3 Select Ipswitch NetFlow Collector, then click Stop. The service stops.
4 To restart the service, select Ipswitch NetFlow Collector again, then click Start. The
service starts.
Using NetFlow Groups
In some cases, you may prefer to track a range of IP addresses as belonging to a different
domain, top level domain, or country than the IP addresses resolve to. For example, internal
IP addresses do not usually have host names registered on a domain name server, so NetFlow
Monitor cannot automatically determine their domains, top level domains, or countries.
To overcome this limitation, NetFlow Monitor lets you use Groups to override the domain,
top level domain, and country of ranges of IP addresses so that each group can be tracked as
a whole. This allows you to easily track sections of your internal network so that you can view
reports by divisions, departments, or other groupings.
Tip: After you configure a group, you can use that group's name to filter reports to show only
the traffic sent to or received by devices that belong to the group.
To create or edit a group:
1 From any workspace view or report in the web interface, select GO. The GO menu
appears.
2 If the NetFlow section is not visible, click NetFlow. The NetFlow section of the GO menu

useful when you need to view data about the traffic generated by a specific computer, to a
specific domain, etc.
After you apply a filter to the Interface Details report, the workspace report that coincides
with the filter reloads with a time graph for the filtered traffic component. For example, if you
apply a filter for the http application, the Top Applications workspace report displays a time
graph of http application use for the time period selected at the top of the Interface Details
report.
You can easily determine which workspace report contains the time graph by looking for the
filter enclosed in parenthesis to the right of the workspace report title name.
Tip: You can remove the applied filter by clicking the red X under the time graph.
30
Using WhatsUp Gold NetFlow Monitor
To filter by keywords:
1 At the top of the report, select Add Filter. Filter fields appear below the button.

4 Click Apply Filters. The report refreshes showing only data that matches the filters you
have configured.
Tip: If you configure a filter incorrectly, you can remove it from the current view by clicking
the red X located to the right of the keyword field.
Filtering by drilling-down
Another way to filter report data is by clicking on report entries, or drilling-down. This method
of report-filtering allows you to dig deeper into data that peaks your interest or raises red
flags—with just one click.
When you click an entry in the farthest-left column of an Interface Details workspace report,
the report reloads using the entry as a filter. Also, you can click inside a workspace report's
graph area to apply a filter.
31
Using WhatsUp Gold NetFlow Monitor
Similarly to filtering by keywords, after you apply a filter to the report, the workspace report
that coincides with the filter will display a time graph for the filtered traffic component. For
example, if you click an entry in the Sender Country column of the Top Sender Countries
workspace report, the workspace report reloads with a time graph for the country that you
clicked.
Several keyword filters coincide with more than one workspace report and more than one
time graph is displayed after the filter is applied. You can easily distinguish which workspace
reports in the Interface Details report are displaying time graphs by looking for the applied
filter's name in parenthesis next to a report name.

About the NetFlow Bandwidth Usage report
The NetFlow Bandwidth Usage report displays network bandwidth usage information.
The report consists of NetFlow workspace reports that summarize the incoming and
outgoing traffic for NetFlow groups and hosts.
ƒ
Bandwidth Usage by Group displays bandwidth usage summaries for each of your
NetFlow groups for the selected time period.
ƒ
Bandwidth Usage by Host displays bandwidth usage summaries for NetFlow hosts that
are using the most bandwidth during the selected time period.
36
Using WhatsUp Gold NetFlow Monitor
There are several ways you can refine this report.
ƒ
Select a different interface. Use the Interface list at the top of the page to select the
interface for which the report data displays.
ƒ

Understanding NetFlow Monitor workspace reports
Workspace reports are the individual small reports displayed in several of the NetFlow
Monitor reports and their views. NetFlow report views are user-customizable; they let you
organize various workspace reports by the type of information they display.
NetFlow workspace reports typically consist of a graph and a table of data related to the
graph.
Workspace reports that display data from NetFlow Monitor can be used within NetFlow
Monitor report views and WhatsUp Gold workspace views.
41
Using WhatsUp Gold NetFlow Monitor
Note: While you can determine which workspace reports appear in workspace views in
NetFlow Monitor and WhatsUp Gold, NetFlow report views are more structured than
WhatsUp Gold workspace views. In WhatsUp Gold, you can position workspace reports
anywhere within a view; in NetFlow Monitor, report positions cannot be modified. As a rule,
sender workspace reports display on the left side of the report, while receiver workspace
reports display on the right side. Further, a page with no sender or receiver reports displays
workspace reports in one column.
NetFlow workspace report types
There are three types of NetFlow workspace reports.
ƒ
Interface Details workspace reports display summary information about specific details
of an interface; for example, applications, protocols, and types of service.
ƒ
Interface Troubleshooting workspace reports display data that would be useful in
troubleshooting bandwidth problems; for example, failed connections.
ƒ
Interface Traffic workspace reports display summary information about an interface's
incoming and outgoing traffic.
These types vary depending from where in the application you modify your report and
workspace views.
If you add workspace reports to the Interface Details report in NetFlow Monitor, you see
Interface Details and Troubleshooting categories on the Configure NetFlow Interface Report
dialog.
42
Using WhatsUp Gold NetFlow Monitor
If you add workspace reports to a workspace view in WhatsUp Gold, you see Interface Details,
Interface Troubleshooting, and Interface Traffic on the Add Content To View dialog.
Navigating workspace reports
There are several ways to navigate NetFlow workspace reports.
ƒ
Workspace report menu (on page 44) gives you options to configure and access help for
each workspace report.
ƒ
Links (on page 44) allow you to apply any criteria shown in a report as a filter.
ƒ
Zoom control (on page 45) lets you change the amount of data shown in line graphs.
ƒ
Informational tooltips (on page 46) alert you to conditions which may warrant further
investigation.
43
Using WhatsUp Gold NetFlow Monitor
Using the workspace report menu
Each workspace report has a menu on the right side of its title bar. Using the workspace
report menu, you can view help for the report, configure the report, export the report data, or
expand and collapse the report.
Workspace report menu buttons
Click the Configure button to open the Configure dialog for the report.
Click the Export button to export report data.
Click the Help button to view the help for the report.
Click the Expand button to expand the report within the workspace view.
Click the Collapse button to collapse the report within the workspace view. Collapsing a
report does not remove it from the workspace view.
Using links in NetFlow workspace reports
Each NetFlow workspace report contains links that allow you to refine the data displayed in
the report. When you click on the data in the first column of one of the workspace report's
rows (or on a pie graph's wedges, or a bar graph's bars), the NetFlow Interface Details report
appears with the selected data applied as a filter.
44
Using WhatsUp Gold NetFlow Monitor
For example, as illustrated in the graphic below, if you click on ipswitch.com in the Top
Sender Domains workspace report, the NetFlow Interface Details report appears with a
Sender Domain filter set to ipswitch.com.
If you are viewing the NetFlow Interface Details report with a filter applied, clicking a link in a
workspace report refreshes the report with the selected data applied as an additional filter
(the previously applied filters remain).
Using zoom controls on line graphs
Workspace reports that include line graphs, such as the Interface Traffic report, allow you to
adjust the window of time for which data is reported using the zoom controls. These controls
are located at the top center of the workspace report.
Zoom controls
Page left
Moves the graph time frame backward by 50% of the total time of the graph.
For example, if the graph shows data from 3:00 PM to 4:00 PM, clicking Page
left shifts the time frame of the graph to 2:30 PM to 3:30 PM.
45
Using WhatsUp Gold NetFlow Monitor
Zoom in
Decreases the amount of time displayed in the report by 50%. For example, if
the report is displaying data for one hour, clicking the Zoom in button decrease
the display time to 30 minutes. The report must display at least 30 minutes. If
you attempt to zoom in on a report that shows 30 minutes, the report refreshes
but the time frame is not changed.
Zoom out
Increases the amount of time displayed in the report. For example, if the report
is displaying data for 30 minutes, clicking the Zoom out button increases the
display time to 1 hour.
Page right
Moves the graph time frame forward by 50% of the total time of the graph. For
example, if the graph shows data from 3:00 PM to 4:00 PM, clicking Page right
shifts the time frame of the graph to 3:30 PM to 4:30 PM.
Using informational tooltips
In some reports, when NetFlow Monitor detects traffic patterns that may indicate a problem
that requires intervention, a yellow warning flag icon is displayed.
Position the mouse cursor over the yellow flag icon to view an information tooltip about the
specific issue, including links to related reports and specific help topics that may help resolve
the issue.
If you do not want to see information tooltips, you can disable them throughout NetFlow
Monitor. It is not possible to disable individual tooltips.
To disable informational tooltips throughout NetFlow Monitor:
1 From any workspace view or report in the web interface, select GO. The GO menu
appears.
2 If the NetFlow section is not visible, click NetFlow. The NetFlow section of the GO menu
appears.
3 Select Configure > NetFlow Settings. The NetFlow Settings dialog appears.
4 Clear Enable information tooltips.
5 Click OK to save changes.
