PRTG Manual: SNMP Dell EqualLogic Member Health Sensor

The SNMP Dell EqualLogic Member Health sensor monitors the health of an array member of an EqualLogic storage system via the Simple Network Management Protocol (SNMP).

For a detailed list and descriptions of the channels that this sensor can show, see section Channel List.

Remarks

Consider the following remarks and requirements for this sensor:

Remark	Description
SNMP v1	This sensor works with SNMP v2c and SNMP v3. It does not support SNMP v1. Make sure that you set the correct SNMP Version in the settings of an object that is higher in the object hierarchy.
IPv6	This sensor supports IPv6.
Performance impact	This sensor has a low performance impact.
Lookups	This sensor uses lookups to determine the status values of one or more channels.

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
dellequallogic
snmpdell

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

Dell EqualLogic Specific

Setting	Description
Array Member	The name of the member that this sensor monitors.
Group ID	The group ID of the member that this sensor monitors.
Member ID	The ID of the group member that this sensor monitors.

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
Average Read Latency	The average read latency
Average Read Latency	The average write latency
Data Read	The data read speed
Data Written	The data write speed
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.
Fan Power Cooling Module [#] Fan [#]	The power of the cooling module fan
Member Health Status	The member health status Up status: Normal Warning status: Warning Down status: Critical, Unknown
Member Status	The member status Up status: Online Warning status: Vacated, Vacating Down status: Offline This channel is the primary channel by default.
Number of Spares	The number of spare drives This channel has a default limit: Lower warning limit: 1
Power Supply Power Cooling Module [#]	The power supply cooling module status Up status: On and Operating Down status: Failed or No Data, No AC Power
RAID Status	The RAID status Up status: Expanding, Mirroring, Ok, Verifying Warning status: Degraded, Reconstructing Down status: Catastrophic Loss, Failed
Storage Free %	The free storage (%)
Temperature Control Module [#] [Module]	The control module temperature
