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).

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

i_round_blueThe 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.

Sensor in Other Languages

  • Dutch: SNMP Dell Hardware
  • French: Dell matériel (SNMP)
  • German: SNMP Dell Hardware
  • Japanese: SNMP Dell ハードウェア
  • Portuguese: Hardware Dell (SNMP)
  • Russian: Оборудование Dell по SNMP
  • Simplified Chinese: SNMP Dell 硬件
  • Spanish: Hardware Dell (SNMP)

Remarks

  • This sensor requires the Dell OpenManage Server Administrator on the target system.
  • 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.
  • This sensor supports IPv6.
  • This sensor has a very low performance impact.

Detailed Requirements

Requirement

Description

Dell OpenManage Server Administrator

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

i_square_cyanFor more information, see the Knowledge Base: What do I need to monitor Dell servers?

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.

i_round_blueIf 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

The tags that the sensor inherits from its parent device, parent group, and parent probe.

i_round_blueThis 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.

i_round_blueIt is not possible to enter tags with a leading plus (+) or minus (-) sign, nor tags with parentheses (()) or angle brackets (<>).

i_round_blueFor 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:

  • 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 (i_priority_1) to the highest priority (i_priority_5).

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.
    i_round_blueIn combination with a change trigger, you can use this to trigger a notification if a change occurs.

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.

i_round_blueYou can set a different primary channel later by clicking b_channel_primary 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.
    i_round_redYou 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. 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 b_inherited_enabled under the corresponding setting name to disable the inheritance and to display its options.

Schedules, Dependencies, and Maintenance Window

i_round_blueYou 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.

Channel List

i_round_blueWhich 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 state

[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
