During maintenance, nodes might be Down for short periods of time. To prevent alert messages and to ensure that your Orion Platform product collects the data you need, place the nodes to Maintenance Mode.

You need Administrator and Node Management rights.

The following maintenance options are available:

  • Mute alerts: data for the node, interfaces, and volumes on the node is collected, but alerts do not trigger.

    Muting alerts is not supported for SRM and VMAN objects.

  • Stop collecting data for the node: data for the node, interfaces, and volumes on the node is not collected, and alerts do not trigger.

    If you stop polling data for a node, polling is also stopped for all interfaces and volumes on the node.

  • Schedule a maintenance period : specify a period of time to stop collecting data or to mute alerts for a node.

Mute alerts

Mute alerts for a node to perform maintenance on the node without interruptions by false positive alerts.

  1. Click Settings > Manage Nodes.
