PRTG Manual: SNMP Dell PowerEdge System Health Sensor

The SNMP Dell PowerEdge System Health sensor monitors the system health of a Dell PowerEdge server via the Simple Network Management Protocol (SNMP).

Remarks

▪This sensor requires that Integrated Dell Remote Access Controller (iDRAC) 7 or the Dell OpenManage Server Administrator (OMSA) are installed on the monitored server.

▪This sensor supports the IPv6 protocol.

▪This sensor has a very low performance impact.

▪This sensor has predefined limits for several metrics. You can individually change these limits in the channel settings. For detailed information about channel limits, see section Channel Settings.

▪This sensor uses lookups to determine the status values of one or more channels. This means that possible states are defined in a lookup file. You can change the behavior of a channel by editing the lookup file that the channel uses. For details, see section Define Lookups.

Detailed Requirements

Requirement	Description
Dell OpenManage Server Administrator or iDRAC 7	This sensor needs the Dell OpenManage Server Administrator (OMSA) tool to be installed on the target device to monitor it. Make sure that you enable SNMP in the OMSA. For details, see the Knowledge Base: What do I need to monitor Dell servers? You can also monitor Dell PowerEdge servers with this sensor via iDRAC 7.

Requirement

Description

Dell OpenManage Server Administrator or iDRAC 7

This sensor needs the Dell OpenManage Server Administrator (OMSA) tool to be installed on the target device to monitor it. Make sure that you enable SNMP in the OMSA.

For details, see the Knowledge Base: What do I need to monitor Dell servers?

You can also monitor Dell PowerEdge servers with this sensor via iDRAC 7.

Add Sensor

The Add Sensor dialog appears when you manually add a new sensor to a device. It only shows the settings that are required to create the sensor. You can change nearly all settings on the sensor's Settings tab after creation.

The settings that you select in the Add Sensor dialog are valid for all sensors that you create when you finish the dialog.

Setting	Description
Chassis	Select the chassis that you want to monitor. PRTG creates one sensor for each chassis that you select. Enable check boxes in front of the respective lines to select the items. Use the check box in the table header to select all items or to cancel the selection. In large tables, use the search function in the upper-right corner.

Basic Sensor Settings

Basic Sensor Settings

Setting	Description
Sensor Name	Enter a name to identify the sensor. By default, PRTG shows this name in the device tree, as well as in alarms, logs, notifications, reports, maps, libraries, and tickets. If the name contains angle brackets (<>), PRTG replaces them with braces ({}) for security reasons. For more information, see the Knowledge Base: What security features does PRTG include?
Parent Tags	Shows tags that the sensor inherits from its parent device, parent group, and parent probe. This setting is for your information only. You cannot change it.
Tags	Enter one or more tags. Confirm each tag with the Spacebar key, a comma, or the Enter key. You can use tags to group objects and use tag-filtered views later on. Tags are not case-sensitive. Tags are automatically inherited. It is not possible to enter tags with a leading plus (+) or minus (-) sign, nor tags with parentheses (()) or angle brackets (<>). For performance reasons, it can take some minutes until you can filter for new tags that you added. The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor: ▪snmpdellsystemhealthsensor ▪systemhealth ▪snmpdell ▪dell
Priority	Select a priority for the sensor. This setting determines the position of the sensor in lists. The highest priority is at the top of a list. Choose from the lowest priority () to the highest priority ().

Usually, a sensor connects to the IP Address/DNS Name of the parent device. See the device settings for details. For some sensors, you can explicitly define the monitoring target in the sensor settings.

Chassis	Shows the chassis that this sensor monitors. PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.
Channel Mask	Shows the channel mask that describes which channels are available. PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.
Data Source	Shows the interface that PRTG uses to get monitoring data. This is either Dell OMSA or iDRAC. PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.

Sensor Display

Setting	Description
Primary Channel	Select a channel from the list to define it as the primary channel. In the device tree, the last value of the primary channel is always displayed below the sensor's name. The available options depend on what channels are available for this sensor. You can set a different primary channel later by clicking below a channel gauge on the sensor's Overview tab.
Graph Type	Define how different channels are shown for this sensor: ▪Show channels independently (default): Show a graph for each channel. ▪Stack channels on top of each other: Stack channels on top of each other to create a multi-channel graph. This generates a graph that visualizes the different components of your total traffic. You cannot use this option in combination with manual Vertical Axis Scaling (available in the channel settings).
Stack Unit	This setting is only visible if you enable Stack channels on top of each other as Graph Type. Select a unit from the list. All channels with this unit are 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.

Primary Channel

Select a channel from the list to define it as the primary channel. In the device tree, the last value of the primary channel is always displayed below the sensor's name. The available options depend on what channels are available for this sensor.

You can set a different primary channel later by clicking below a channel gauge on the sensor's Overview tab.

Graph Type

Define how different channels are shown for this sensor:

▪Show channels independently (default): Show a graph for each channel.

▪Stack channels on top of each other: Stack channels on top of each other to create a multi-channel graph. This generates a graph that visualizes the different components of your total traffic.
You cannot use this option in combination with manual Vertical Axis Scaling (available in the channel settings).

Stack Unit

This setting is only visible if you enable Stack channels on top of each other as Graph Type. Select a unit from the list. All channels with this unit are 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.

Inherited Settings

By default, all of these settings are inherited from objects that are higher in the hierarchy. We recommend that you change them centrally in the root group settings if necessary. To change a setting for this object only, click under the corresponding setting name to disable the inheritance and to display its options.

For more information, see section Inheritance of Settings.

Scanning Interval

For more information, see section Root Group Settings, section Scanning Interval.

Schedules, Dependencies, and Maintenance Window

You cannot interrupt the inheritance for schedules, dependencies, and maintenance windows. The corresponding settings from the parent objects are always active. However, you can define additional schedules, dependencies, and maintenance windows. They are active at the same time as the parent objects' settings.

Schedules, Dependencies, and Maintenance Window

For more information, see section Root Group Settings, section Schedules, Dependencies, and Maintenance Window.

Access Rights

For more information, see section Root Group Settings, section Access Rights.

Channel Unit Configuration

Which channel units are available depends on the sensor type and the available parameters. If no configurable channels are available, this field shows No configurable channels.

Channel Unit Configuration

For more information, see section Root Group Settings, section Channel Unit Configuration.

Channel List

Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.
