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.

Orion Platform 2017.3 and later provide access to the maintenance options from the Manage Entities view: select nodes, click More, and select a maintenance option.

Nodes with muted alerts, or with a planned maintenance period of suspended alerts are marked with a crossed-out loudspeaker icon on Manage Entities. Click the icon to cancel the maintenance.

Mute alerts

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

  1. Click Settings > Manage Nodes.
  2. Select the nodes and click Maintenance Mode > Mute Alerts.

    You do not receive alerts until you Resume Alerts for the nodes.

Resume alerts

After maintenance, resume alerts for the node, interfaces, and volumes on the node again.

  1. Go to the node details view.
  2. In the Management resource, select Maintenance Mode > Resume Alerts (Unmute).

Alerts for the node are active.

Stop collecting statistics

To stop collecting statistics for nodes during maintenance, unmanage the nodes.

  1. Click Settings > Manage Nodes.
  2. Select the nodes, and click Maintenance Mode > Unmanage Now.

NPM stops collecting statistics for the node until you Manage the node again.

Start collecting statistics

After maintenance, start polling the node again.

  1. Go to the Node Details view.
  2. In the Management resource, select Maintenance Mode > Manage Again.

NPM collects performance and availability data again, and displays the data in the Orion Web Console.

  2. Select the nodes and click Maintenance Mode > Schedule.
  3. Select the maintenance option:
    • Mute alerts - data for the node is collected, but alerts do not trigger.
    • Stop polling the node - data for the node is not collected and alerts do not trigger.
  4. Specify the maintenance period, and click Schedule.

    The maintenance is scheduled.

Change scheduled maintenance

You can reschedule the maintenance or change the maintenance mode.

The maintenance schedule is adjusted according to your settings.
