PRTG Manual: SNMP Dell Hardware Sensor

The SNMP Dell Hardware sensor monitors performance counters on a Dell hardware device via the Simple Network Management Protocol (SNMP).

The data that you can monitor with this sensor depends on the available performance counters on the target system.

The SNMP Dell Hardware sensor does not appear as a running sensor, instead it is created as an SNMP Custom Advanced sensor or an SNMP Custom Table sensor with up to 10 channels per category.

Remarks

Consider the following remarks and requirements for this sensor:

Remark	Description
Dell OpenManage Server Administrator	This sensor requires the Dell OpenManage Server Administrator on the target system. Make sure that you enable SNMP in the OMSA. For more information, see the Knowledge Base: What do I need to monitor Dell servers?
Counters	Select the counters that you want to monitor with caution. We recommend that you select only a few counters in the Add Sensor dialog. Use the search in the table header to filter for specific counters. Selecting too many counters might result in thousands of sensors or the sensor creation is canceled.
IPv6	This sensor supports IPv6.
Performance impact	This sensor has a very low performance impact.

Basic Sensor Settings

The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:

dell

For more information about basic sensor settings, see section Sensor Settings.

Dell Hardware Specific

Setting	Description
Interface	The name of the interface (performance counter) that this sensor monitors.
Unit String	Define the unit of the numeric data that the sensor receives at the specified OID. Enter a string.
Multiplication	If you want to multiply the received data with a certain value, enter the multiplier. Enter an integer.
Division	If you want to divide the received data by a certain value, enter the divisor. Enter an integer.
If Value Changes	Define what the sensor does when its value changes: Ignore (default): Do nothing. Trigger 'change' notification: Send an internal message that indicates a change. In combination with a change trigger, you can use this to trigger a notification if a change occurs.

Sensor Display

Setting	Description
Primary Channel	Select a channel from the list to define it as the primary channel. In the device tree, PRTG displays the last value of the primary channel 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 this sensor shows different channels: 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 select Stack channels on top of each other above. Select a unit from the list. PRTG stacks all channels with this unit 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.

Description

Primary Channel

Select a channel from the list to define it as the primary channel. In the device tree, PRTG displays the last value of the primary channel 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 this sensor shows different channels:

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 select Stack channels on top of each other above.

Select a unit from the list. PRTG stacks all channels with this unit 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.

Channel List

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

Channel	Description
Downtime	In the channel table on the Overview tab, this channel never shows any values. PRTG uses this channel in graphs and reports to show the amount of time in which the sensor was in the Down status
[Performance Counter]	The value returned by a specific Dell hardware OID, for example Data about the system management software Data about system status Information about chassis and BIOS Various hardware parameters Other valuable data
