You may find that nodes are displayed in the Orion Web Console with a status of Unknown. This can be due to one of several reasons including invalid polling methods, stuck jobs, and incorrect engine assignments.

Orion Platform

This occurs when the status pollers are missing from the pollers table in the database.
 

Resolution 1:

1. If available, move the node to a different poller and wait for maybe 20 minutes
2. Move back the node to the original poller 

Resolution 2:

1. On the Orion Web Console, go to Settings > Manage Nodes.
2. Select the unknown nodes and click Edit Properties.
3. On the Edit Node page, change the polling method. For example, change ICMP to SNMP.
4. Click Submit.
5. Repeat Steps 1-2 and assigns the original polling method.
6. Click Submit.
7. Allow Orion Web Console 10 minutes to poll. After ten minutes, the nodes' status should now be correctly displayed.

 

Resolution 3:

1. Check Database Manager for the following:
   1. Engines table > right-click New Query > Execute Query > It will show your pollers and their respective engine IDs
   2. Nodes Data table > right-click New Query > Execute Query > It will show all your nodes (with NodeID and other details, including EngineID), scroll to the right, and look for the EngineID column

2. If they are assigned to the wrong EngineID, you have the option to do it in the Database Manager (in the NodesData table) and run a query to change the EngineID to the correct one,
