PRTG Manual: SNMP NetApp System Health Sensor

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

The 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:

• snmpnetappsystemhealthsensor
• snmpnetapp
• netapp

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 ().

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.

CPU Load

The CPU load (%)

Disks Active

The number of active disks

Disks Being Added

The number of disks being added

Disks Being Scrubbed

The number of disks being scrubbed

Disks Failed

The number of failed disks

This channel has a default limit

• Upper error limit: 0

Disks Failing Soon

The number of disks that will fail soon

This channel has a default limit

• Upper error limit: 0

Disks Out Of Date

The number of disks that are out of date

This channel has a default limit

• Upper error limit: 0

Disks Reconstructing

The number of disks that are reconstructing

Disks Reconstructing Parity

The number of disks that are reconstructing parity

Disks Spare

The number of spare disks

This channel has default limits

• Lower error limit 1
• Lower warning limit: 2

Disks Total

The total number of disks

This channel is the primary channel by default.

Disks Verifying Parity

The number of disks that are verifying parity

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
