105 SNMP Dell PowerEdge System Health Sensor
6.8.105 SNM P Dell PowerEdge Sy stem Health Sensor
The SNMP Dell PowerEdge System Health sensor monitors the system health of a Dell
PowerEdge server using Simple Network Management Protocol (SNMP). It can show the global system status, the power supply status, the temperature status, the cooling device status, the memory device status, the voltage status, and many more, depending on the available components of your device.
This sensor type has predefined limits for several metrics. These limits can be changed individually in the channel settings. For detailed information about channel limits please refer to the section
1709
.
This sensor type uses lookups to determine the status values of some sensor channels. For details, please see section
2039
.
For a general introduction to the technology behind SNMP, please see
1955
section.
Requirement: Dell OpenManage Server Administrator or iDRAC 7
This sensor needs the Dell OpenManage Server Administrator tool to be installed on the device in order to monitor PowerEdge servers. Please make sure that you enable SNMP in the
OpenManage Server Administrator. For details, please see section More below. Note: You can also monitor Dell PowerEdge servers with this sensor type via Integrated Dell Remote Access
Controller (iDRAC) 7.
Add Sensor
The Add Sensor dialog appears when adding a new sensor on a device manually
220
. It only shows the setting fields that are imperative for creating the sensor. Therefore, you will not see all setting fields in this dialog. You can change all settings in the sensor's Set t ings tab later.
In order to monitor the health status of a Dell PowerEdge server, PRTG will create one sensor for each chassis you choose. The settings you make in this dialog are valid for all of the sensors that are created.
The following settings for this sensor differ in the 'Add Sensor' dialog in comparison to the sensor's settings page:
Dell PowerEdge Sy st em Healt h Specific
Chassis Select the chassis you want to add a sensor for. A list of all available items is shown with their name. Select the desired items by adding check marks in front of the respective lines. One sensor will be created for each selection. You can also select and deselect all items by using the check box in the table head.

Sensor Settings
On the sensor's details page, click on the Set t ings tab to change settings.
Note: If not set explicitly in a sensor's settings, it will connect to the IP Address or DNS Name defined in the settings of the parent device the sensor is created on.
Basic Sensor Set t ings
Sensor Name Enter a meaningful name to identify the sensor. The name will be shown by default in the device tree and in all alarms.
Tags
Priority
Enter one or more tags, separated by space or comma. You can use tags to group sensors and use tag-filtered views later on. Tags are not case sensitive. We recommend using the default value. You can add additional tags to it, if you like. Other tags are
89
from objects further up in the device tree. Those are not visible here.
Select a priority for the sensor. This setting determines where the sensor will be placed in sensor lists. Top priority will be at the top of a list. You can choose from one star (low priority) to five stars
(top priority).
Dell PowerEdge Sy st em Healt h Specific
Chassis Shows the chassis this sensor monitors. Once a sensor is created this value cannot be changed. It is shown for reference purposes only. If you need to change this, please add the sensor anew.
Channel Mask
Data Source
Shows the channel mask that describes which sensors are available. Once a sensor is created this value cannot be changed. It is shown for reference purposes only. If you need to change this, please add the sensor anew.
Shows the interface which is used to get monitoring data. This is either Dell OpenManage Server Administrator (OMSA) or Integrated
Dell Remote Access Controller (iDRAC).

Sensor Display
Primary Channel
Chart Type
Stack Unit
Select a channel from the list to define it as the primary channel. In the device tree, the last value of the primary channel will always be displayed underneath the sensor's name. The available options depend on what channels are available for this sensor. Note: You can set another primary channel later by clicking on the pin symbol of a channel in the sensor's overview tab.
Define how different channels will be shown for this sensor.
§ Show channels independent ly (default ): Show an own graph for each channel.
§ St ack channels on t op of each ot her: Stack channels on top of each other to create a multi-channel graph. This will generate an easy-to-read graph which visualizes the different components of your total traffic. Note: This option cannot be used in combination with manual Vertical Axis Scaling (available in the
1709
settings).
This setting is only available if stacked graphs are selected above.
Choose a unit from the list. All channels with this unit will be stacked on top of each other. By default, you cannot exclude single channels from stacking, if they use the selected unit.
However, there is an advanced procedure to do so.
Scanning Int erval
Scanning Interval The scanning interval determines the time the sensor waits between two scans. Select a scanning interval (seconds, minutes, or hours) from the list. You can change the available intervals in
1839
.
Schedules, Dependencies, and Maint enance Window
Note: Inheritance for schedules, dependencies, and maintenance windows cannot be interrupted; the according settings from the parent objects will always be active. However, you can define additional settings here. They will be active in parallel to the parent objects' settings.
Schedule Select a schedule from the list. Schedules can be used to monitor for a certain time span (days, hours) throughout the week. With the period list option it is also possible to pause monitoring for a specific time span. You can create new schedules and edit existing ones in the
1817
. Note: Schedules are generally inherited. New schedules will be added to existing ones, so all schedules are active.

Schedules, Dependencies, and Maint enance Window
Maintenance Window Specify if you want to set-up a one-time maintenance window.
During a maintenance window this object and all child objects will not be monitored. They will enter a paused state then. Choose between:
§ Not set (monit or cont inuously ): No maintenance window will be set.
§ Set up a one-t ime maint enance window: Pause monitoring within a maintenance window.
Maintenance Begins At This field is only visible if maintenance window is enabled above.
Use the date time picker to enter the start date and time of the maintenance window.
Maintenance End At This field is only visible if maintenance window is enabled above.
Use the date time picker to enter the end date and time of the maintenance window.
Dependency Type
Dependency
Define a dependency type. Dependencies can be used to pause monitoring for an object depending on the status of another. You can choose between:
§ Use parent : Pause the current sensor if the device it is created on is in a Down status, or if it is paused by another dependency.
§ Select object : Pause the current sensor if the device it is created on is in an Down status, or if it is paused by another dependency. Additionally, pause the current sensor if a specific other object in the device tree is in a Down status, or if it is paused by another dependency. Select below.
§ Mast er object for parent : Make this sensor the master object for its parent device. The sensor will influence the behavior of the device it is created on: If the sensor is in a Down status, the device will be paused. For example, it is a good idea to make a
Ping sensor the master object for its parent device to pause monitoring for all other sensors on the device in case the device cannot even be pinged. Additionally, the sensor will be paused if the parent group of its parent device is in a Down status, or if it is paused by another dependency.
Note: Testing your dependencies is easy! Simply choose Simulat e
Error St at us from the context menu of an object that other objects depend on. A few seconds later all dependent objects should be paused.
This field is only visible if the select object option is enabled above.
Click on the reading-glass symbol and use the
159 to choose an object on which the current sensor will be dependent on.

Schedules, Dependencies, and Maint enance Window
Delay (Seconds) Define a time span. After the master object for this dependency comes back to an Up status, monitoring of the depending objects will be additionally delayed by the defined time span. This can help avoid false alarms, for example, after a server restart, by giving systems more time for all services to start up. Please enter an integer value in seconds. Note: This setting is not available if you choose this sensor to be the Mast er object for parent . In this case, please define delays in the parent
272
or the
253
.
Access Right s
User Group Access Define which user group(s) will have access to the object you're editing. A table with user groups and right is shown; it contains all user groups from your setup. For each user group you can choose from the following access rights:
§ Inherit ed: Use the settings of the parent object.
§ None: Users in this group cannot see or edit the object. The object does not show up in lists and in the device tree.
Exception: If a child object is visible to the user, the object is visible in the device tree, though not accessible.
§ Read: Users in this group can see the object and review its monitoring results.
§ Writ e: Users in this group can see the object, review its monitoring results, and edit the object's settings. They cannot edit access rights settings.
§ Full: Users in this group can see the object, review its monitoring results, edit the object's settings, and edit access rights settings.
You can create new user groups in the
1861
settings. To automatically set all objects further down in the hierarchy to inherit this object's access rights, set a check mark for the Revert children's access right s t o inherit ed option.
For more details about access rights, please see section
