Preface
Revised: February 2016
Cisco Videoscape Distribution Suite (VDS) Transparent Caching (TC) Analytics provides visibility into network performance, subscriber trends, and cache content. This business intelligence engine leverages industry leading technology for the monitoring, reporting, and analysis of key performance indicators
(KPIs) with unique insight from the Cisco VDS TC cache engines.
The core of the Cisco VDS TC Analytics solution consists of KPIs and a Cache Detail Record (CDR) database, which the VDS TC Analytics server uses to collect and store information from the Cisco VDS
TC cache engines. Cisco VDS TC systems on the network are connected to the foundation over the ISP management network. Details from these cache engines are aggregated and analyzed to enable a network-wide view of traffic, as it is delivered from the perspective of the VDS TC cache engines.
Administrators access this information through a central Cisco VDS TC Analytics server by viewing dashboards and pre-defined reports, and can perform on-demand analysis of the network.
Analysis is delivered for all levels of the organization in a variety of displays. Different report packages are available for various levels of the organization:
• Network engineers obtain the details required for managing and expanding their networks.
•
•
The finance department can gain visibility into savings and growth planning.
Executives can draw summaries based on media trends and subscriber patterns
• The marketing team can acquire insight necessary to develop new products and services.
Information is presented as webpage dashboards, which provide quick access to information, or in PDF and HTML formats.

Overview
Cisco VDS TC Analytics provides a high quality and rich variety of marketing and network engineering performance reports. These dashboard reports provide the most important and valuable performance
KPIs that give a clear view of the business status. By just clicking the main window, the user has access to the Dashboard Reports Navigation.
Cisco Videoscape Distribution Suite Transparent Caching Analytics User Guide vii
Preface
Cisco VDS TC Analytics Navigational Overview
The VDS TC Analytics data collection engine and data intelligence system produces custom reports about the media that flows through the entire pipeline. These reports are designed to provide analytical answers to key business questions, such as content type distribution, the percentage of users driving bandwidth growth, new and potential services, P2P class of service, the popularity of users by protocols or services, individual system output, cache consumption, the IP addresses of the highest volume users, services that are consumed by the highest volume users, weight items and number of requests, overall load balance, and so on.
VDS TC Analytics translates the data that is generated by VDS TC cache engines and displays it in charts and data tables designated according to specific Cisco Analytics user groups, such as network engineers and operators, marketing personnel, and executives.
For each organizational user group, VDS TC Analytics presents pertinent information in predefined sets of displays. The At a Glance dashboard is the summary page that opens for each of the organization user groups, delivering an immediate overview at patterns and trends. At a Glance reports present the daily summaries for the time frame you select, according to daily average values, breaking down the information by services and protocols. Plotted comparisons of information visually convey the behavior of traffic, as it is served from the VDS TC cache engine (cache traffic) and from the world (clear traffic).
You can easily list all charted data in numerical values to enhance your insight.
From this personalized dashboard look, you can drill down for more detailed analysis available through the Data Mining dashboard. The Data Mining reports offer advanced filtering capabilities, according to five minute polling, for the comparison of KPIs across services and protocols over any time frame.
Aggregate views for the entire network can be compared by IP address, zone, POP, or individual VDS
TC systems.
You can save or print every chart and data table in PDF or HTML format.
Cisco VDS TC Analytics Navigational Overview
Cisco VDS TC Analytics has an easy to use GUI to help you navigate to the various dashboards and reports, which are accessed through the main menu of the VDS TC Analytics user interface (UI).
Clicking each choice allows the user to adjust what they view and how they view it.

Terminology
Terminology
The VDS TC Analytics Terminology table describes terms and concepts that apply to the VDS TC
Analytics Software.
Table 2 VDS TC Analytics Terminology
Term
AVG
Bytes Hit Ratio (BHR) The number of bytes of cached out traffic divided by the total number of bytes of traffic, whether it was cached or not. For example, a 60% bytes hit ratio means that 60% of the overall bandwidth came from the cache and
40% came from the world.
cache in A connection where the object requested by a subscriber does not exist in the cache (which creates a “miss”), and the requested incoming data from the world is stored in the cache.
cache cache out
Description
Average cache productivity cache quality of experience (QoE)
CDR clear
Traffic served only from VDS TC.
A connection where the object requested by a subscriber exists in the cache
(which creates a “hit”), and the request is served from the cache as outgoing traffic to the subscriber.
The total cached out traffic divided by the total cached in traffic.
The average delivery speed of traffic that is served from VDS TC per active subscriber. QoE is analyzed by comparing cache QoE with clear QoE.
Cache/Content Data Record
The status of a subscriber request when the requested file segment does not exist in the cache. Subsequently, this object is either cached in or forwarded.
It is considered as traffic that is delivered directly from the Internet.
clear QoE
CLI
CMDB miss
The average delivery speed of traffic served directly from the Internet (VDS
TC clear) per active subscriber. QoE is analyzed by comparing clear QoE with cache QoE.
command-line interface
The status of a subscriber request when the requested file segment does not exist in the cache due to an unexpected deletion or corruption.
A connection where P2P or HTTP file segments are transferred.
data downstream forward hit hit miss ratio
I2W
Objects transmitted from the world to the subscriber. Also called W2I.
The process of forwarding an object directly to its requesting subscriber without caching it. This is applied to an object that does not yet exist in the cache. At this stage, it is only listed in the cache, according to the predefined license rules of the platform ( see verify), and will only be cached upon future request.
The status of an ISP subscriber request when the requested file segment exists in cache. Subsequently, this object is cached out.
The number of hits divided by the number of misses.
Upstream data flowing from the ISP to the world.

Top 5 Percentages Subscriber IP Addresses
General Notes for Charts and Reports
• Current day information not available: Charts that rely on information for IPs and domains require an additional day for analysis. Because IP information is collected between 00:01 and 24:00 each day, and only analyzed after it is collected, no information is available for the current day, therefore you can only present information up to the previous day. IP information for the current day can only be presented the day after.
Top 5 Percentages Subscribers
The Top 5 Percentage of Subscribers tab provides information on the top 5 percent of the subscribers for selected clear and cache requests by subscriber name. This summarized view focuses on the overall subscriber requests or cached requests.
The Top 5 Percentage of Subscribers tables show the subscribers that are most highly served from both the Internet (Clear) and Cisco Analytics (Cache), broken down by both total traffic capacity and the total number of requests. By default, information is presented for the top 5 percent of subscribers that scored

Data Mining for Marketing
The Data Mining Marketing reports provide an inclusive filtering mechanism that allows you to gather specific information, uncovering traffic, domain, and IP patterns for individual systems. Data Mining is intended for drilling-down into the performance of specific systems, top subscribers, and top domains, by services or protocols. Data Mining presents five minute polling values (At a Glance charts are based on daily average values), arranged in the following charts and data tables.

General Notes for Charts and Reports
•
•
Current day information not available: Because IP information is collected between 00:01 and
24:00 each day, and only analyzed after it is collected, no information is available for the current day for reports that require IP address and domain information. Therefore you can only present information up to the previous day. IP and domain information for the current day can only be presented the day after.
Selected time frame determines granularity: The selected time frame determines the chart granularity. A chart or report with a time frame of up to and including 3 days, displays five minute polling values. A chart or report with a time frame from 4 days to 30 days displays hourly average points, which calculate all the five minute samples in each hour. A chart or report that has a time frame of over 30 days displays only daily average values.
Content Analysis
The Content Analysis reports enable you to analyze the subscriber traffic patterns, by default filtered by services, for the selected time frame, which by default is the last seven days. Information can be displayed for a specific user, by either services or protocols. You can also filter the information that is displayed based on systems, zone, POP, domain, subscriber IP, and host IP. By default, information is displayed as numerical values. You can also choose to display information is as a pie chart and bar charts.
In this tab, the default Filter By preferences are set to display the previous seven days for the entire network by services, sorted by Subscribers Popularity. You can filter information by a specific user, by either services or protocols, and you can filter out several systems

General Notes for Charts and Reports
• Current day information not available: Charts that rely on information for IPs and domains require an additional day for analysis. Because IP information is collected between 00:01 and 24:00 each day, and only analyzed after it is collected, no information is available for the current day, therefore you can only present information up to the previous day. IP information for the current day can only be presented the day after.
Traffic Analysis
The Traffic Analysis tab delivers immediate visibility of the system performance, based on the selected time frame, which by default is the current week. This summarized view focuses on the overall subscriber consumption, or total downstream traffic, in comparison with the cached out traffic.

Current day information not available: Because IP information is collected between 00:01 and
24:00 each day, and only analyzed after it is collected, no information is available for the current day for reports that require IP address and domain information. Therefore you can only present information up to the previous day. IP and domain information for the current day can only be presented the day after.
Selected time frame determines granularity: The selected time frame determines the chart granularity. A chart or report with a time frame of up to and including 3 days, displays five minute polling values. A chart or report with a time frame from 4 days to 30 days displays hourly average points, which calculate all the five minute samples in each hour. A chart or report that has a time frame of over 30 days displays only daily average values.
Content Analysis
The Content Analysis reports enable you to analyze subscriber traffic patterns, filtered by services (the default in this tab), for the selected time frame, which is the last seven days by default. You can filter the information for a specific subscriber IP, by either services or protocols, and you can filter traffic based on the zone, POP, and system. Information is displayed in numerical values and with horizontal bars to provide visualize comparisons within each column. You can also choose to view the data in charts as well.
In this tab, the default Filter by preferences are set to display information for all subscribers, for all systems, by services. You can filter information by a specific IP address, select only services or protocols, pick a specific system, zone, or POP, and change the time frame. Your Filter By selections are passed on to all of the Network Engineering > Data Mining tabs.

Policy Reports
The Policy Analysis Dashboard provides an assortment of comprehensive reports that capture the statistics about traffic based on the rules, policies, and categories the traffic fall into.
All explicitly created policies are global and are not connected to any configuration. If a global policy is changed, it will be changed in all of the configuration versions. All implicitly created policies are connected to their rules; they are not shown in the policies list and are deleted together with the rules.

Current day information not available: Because IP information is collected between 00:01 and
24:00 each day, and only analyzed after it is collected, no information is available for the current day, therefore you can only present information up to the previous day. IP information for the current day can only be presented the day after.
Selected time frame determines granularity: The selected time frame determines the chart granularity. A time frame of less than 3 days displays five minute polling values. A time frame of over 3 but less than 33 days, displays hourly average points, calculating all of the five minute samples in each hour. A time frame of over 32 days reduces chart granularity to display only daily average values.
Categories Analysis
The Categories Analysis reports provide visibility into content compared by the category that the traffic falls into displayed as both a daily average and as a total for the time frame that is selected.

Current day information not available: Because IP information is collected between 00:01 and
24:00 each day, and only analyzed after it is collected, no information is available for the current day, therefore you can only present information up to the previous day. IP information for the current day can only be presented the day after.
Selected time frame determines granularity: The selected time frame determines the chart granularity. A time frame of less than 3 days displays five minute polling values. A time frame of over 3 but less than 33 days, displays hourly average points, calculating all of the five minute samples in each hour. A time frame of over 32 days reduces chart granularity to display only daily average values.
Traffic Analysis
The Summary Traffic Analysis tab delivers immediate visibility of the performance across all systems, based on the selected time frame. This summarized view focuses on the overall subscriber consumption, or total downstream traffic, in comparison with the cached out traffic, incoming traffic downstream, and is plotted by five minute polling values.

Frequently Asked Question
Revised: February 2016
This appendix provides answers to some frequently asked questions about VDS TC Analytics.
Time Frame
What is the default time frame for the reports?
The default time from for reports vary, although most of the reports have a default time from of the last seven days. You can change the time frame at anytime. In the Filter By section enter the From and To dates that you want, or use the calendar to select them, and then click Apply . The dates appear in MM/DD/YY format. The chart or report is regenerated for the new time frame and the time frame is displayed in brackets in the chart or report title bar. The new time frame that you enter is passed on to the other tabs in the same dashboard.
Does the selected time frame change the plotted value and chart granularity?
In Data Mining, the selected time frame determines chart granularity. A chart or report with a time frame of up to and including 3 days, displays five minute polling values. A chart or report with a time frame from 4 days to 30 days displays hourly average points, which calculate all the five minute samples in each hour. A chart or report that has a time frame of over 30 days displays only daily average values.
How do you determine the time frame to be displayed?
You can change the time frame at any time and in any report, using the Filter By section of each tab.
The filtering preferences that are set in one tab are automatically carried on to all of the other tabs in that specific dashboard.
Why is there no information displayed for the current day?
Because content information is collected between 00:01 and 24:00 each day and only then analyzed, information for the current day is unavailable in some tabs. Although the last seven days is the default Data Mining time frame, in the Top Subscribers, Top Contents, and Traffic Distribution tabs you can only present information up to the previous day. Current day IP or domain information can only be presented the day after.

Filtering
Appendix A Frequently Asked Question
Why is there a discrepancy in traffic patterns?
If traffic patterns do not make sense, it could be because the clocks of the VDS TC Analytics Server and the VDS TC cache engines are not synchronized, causing a time mismatch.
Is daylight savings time automatically supported?
Daylight savings time is not supported. You must resynchronize the VDS TC Analytics clock and the VDS TC cache engine clocks, to ensure accurate display of information.
Filtering
How is data filtered for display?
In each tab, Filter By settings define the data querying preferences. You can change filtering preferences at any time and in any tab. Filtering preferences are carried on to all of the other tabs in a dashboard, but not between dashboards.
At a Glance provides simplifies filtering options that only allow time frame filtering. Data Mining provides in-depth filtering options, allowing you to set specific systems criteria and display either services or protocols. Note that you must click Apply to refresh the page and display the information according to what you selected in Filter By.
Note Different reports in the Data Mining tabs will have different Filter By options, depending on what the report is showing.
Why is no information presented for the current day?
Charts that rely on data of IPs and domains require an additional day for analysis. Because information is collected between 00:01 and 24:00 each day, and then analyzed, no information is available for the current day. Even when the default time frame includes the current day, you can only present information up to the previous day for charts that rely on data from IPs or domains.
Current day IP or domain information can only be presented the day after.
Why is the display not refreshed to show latest filtering selection?
After making a new selection in the Filter By section, you must always click Apply . Clicking Apply refreshes the charts to present the newly selected filtering criteria.
Data Collection
How is data collected by Analytics?
VDS TC Analytics retrieves information from SNMPs that are generated and controlled by your
Cisco Analytics management server(s). Upon installation, the VDS TC Analytics architecture and collector parameters are set using the Configuration tab.
How to change SNMP poll intervals and CDR data collection?
SNMP polling and CDR data collecting parameters are defined in the Configuration tab. By default,
SNMP polling intervals are every 5 minutes. To change these values you must be assigned to either the Admin or User group and you must be assigned the Network Engineering Values package.
