PRTG Manual: VMware Datastore (REST) Sensor

Credentials

The sensor requires credentials for VMware vSphere in the settings of the parent device.

Meta-scan

This sensor uses the meta-scan feature. After sensor creation, some settings might appear for reference purposes only.

IPv6

This sensor supports IPv6.

Performance impact

This sensor has a very low performance impact.

Lookups

This sensor uses lookups to determine the status values of one or more channels.

Limits

This sensor has predefined limits for one or several metrics.

Datastore ID

Shows the managed object ID of the datastore that this sensor monitors, for example datastore-18126.

Name

Shows the name of the datastore that this sensor monitors.

Type

Shows the type of datastore that this sensor monitors, for example VMFS, NFS, NFS41, vSAN, or VVOL.

Capacity

Shows the total capacity of the datastore that this sensor monitors.

Inaccessible Datastore Handling

Select how the sensor handles an inaccessible datastore:

• Show down status when datastore is inaccessible (default): Immediately show the Down status when the sensor cannot reach the datastore.
• Ignore inaccessible state: The sensor never shows the Down status based on the Accessible channel.

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.

Result Handling

Define what PRTG does with the sensor result:

• Discard result (default): Do not store the sensor result.
• Store result: Store the sensor result and the last response in the \Logs\sensors subfolder of the PRTG data directory on the probe system. The file name is Result of Sensor [ID].log. This setting is for debugging purposes. PRTG overwrites this file with each scanning interval.

This option is not available when the sensor runs on the hosted probe of a PRTG Hosted Monitor instance.

In a cluster, PRTG stores the result in the PRTG data directory of the master node.

Accessible

If the datastore is accessible

• Up status: Yes, No (Ignore)
• Down status: No
• Unknown status: Unknown

If you chose to ignore the accessible status of the datastore in Datastore Settings, this channel shows No (Ignore) and the sensor remains in the Up status when the datastore is not accessible.

Available Capacity

The available capacity (the physically or virtually available size of the datastore)

Datastore Access

The access type of the datastore

• Up status: Shared, Exclusive (Single-Host)
• Unknown status: Unknown

Disk Count

The number of disks

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.

Free Space

The free space available on the datastore

PRTG considers thick-provisioned and thin-provisioned virtual disks when it calculates the free space.

Free Space %

The free space (%) available on the datastore

PRTG considers thick-provisioned and thin-provisioned virtual disks when it calculates the free space.

This channel has default limits:

• Lower error limit: 5%
• Lower warning limit: 10%

This channel is the primary channel by default.

VM Count

The total number of virtual machines (VM)

VMs Powered Off

The number of offline VMs

VMs Powered On

The number of online VMs

VMs Suspended

The number of suspended VMs
