Monitor volumes in the Orion Platform

This topic applies to all Orion Platform products.

When you add nodes for monitoring, the Orion Platform checks for volumes on the nodes. You can select volumes to monitor.

Starting with Orion Platform 2020.2, you can configure new warning and critical volume statuses based on usage thresholds. You can view details on volume usage in tooltips.

Volumes can contribute to the node status. Volumes as node status contributors are enabled by default on new installs. On upgrades, you need to enable them as status contributors manually.

Specify volumes for monitoring

  • Select the volumes to monitor when importing discovered nodes. See Add discovered devices.
  • Select the volumes to monitor when adding a single node to the Orion Platform.
  • To monitor volumes on an already monitored node, go to the Node Details view, click List resources in the Management widget, and ensure that the volumes are selected.

View details for volumes

To see monitored volumes on a node:

  1. Go to the node details view, click the Vital Stats subview on the left.

  2. Review the Disk Volumes widget that lists monitored volumes on the node. If you cannot see the widget, there are no volumes monitored on the node.

    You can also add the All Volumes widget to your views. On summary views, it lists all volumes relevant for the view. On node details view, it lists all volumes relevant for the node.

  3. Click a volume to go the volume details view. The view displays widgets that help you set thresholds and provide more details for the volume.

Configure volume thresholds

Starting with Orion Platform 2020.2, you can configure independent warning and critical thresholds for Percent Disk Space Used on individual volumes. In previous versions, volume thresholds are configured globally.

Customize thresholds for individual volumes

  1. On the Volume Details view, click Edit Volume in the Management widget.
  2. On Edit volume, select Override Orion General Thresholds, and specify the new thresholds for the volume. Select the threshold and an appropriate operator. You can also use:

When a volume exceeds the configured condition, the volume status changes to Critical or Warning.

Disable thresholds for individual volumes

If you are using fixed size SWAP volumes or source media volumes, you might need to disable thresholds so that these volumes are not flagged with the Critical status or to prevent false positive alerts.

  1. On the Volume Details view, click Edit Volume in the Management widget.
  2. On Edit volume, select Override Orion General Thresholds, and clear the box for Warning and/or Critical threshold.

The cleared threshold will not be used when evaluating the volume status.
