Switch Stack widget or resources are not showing in NPM

In this article, you will find suggestions on addressing missing Switch Stack widgets and resources on the Node Details page of the node, which is a member of a switch stack.

Example: One of the stack switches shows the stack icon on the left-hand side

but the other does not.

Both nodes are recognized as having two switches, as it shows the power supply fans, etc. in the Hardware Health widget.

• The switch stack poller is not assigned to the node.
• It is also possible that a switch stack poller is missing or could be corrupted after installing a hotfix or upgrading the versions.

1. Verify if the switch stacks native poller (N.SwitchStack.SNMP.Cisco) has been assigned to the affected node from the Pollers table by running the following SQL query (replace NODEID with relevant value).

   SELECT * FROM [Pollers]
   WHERE [NetObjectID] = NODEID
   AND [PollerType] = 'N.SwitchStack.SNMP.Cisco'

   Sample Output will be something like this:

   PollerType	NetObjectID	Enabled
   N.SwitchStack.SNMP.Cisco	441	FALSE

   
    
2. If the native poller isn't assigned, assign it to the affected node.
   1. Go to Settings > All Settings > 'Node & Group Management' section > Manage Pollers
   2. In the GROUP BY column on the left side, click on SolarWinds Native Poller
   3. Check the Switch Stack poller, then click on ASSIGN
       
      
       
   4. Search for or find the node not showing as a Switch Stack, and toggle OFF to ON.
       
      
   5. Go back to the Node Details page and click on Rediscover.
   
    
3. After following the steps above, if the details page still does not show the Switch Stack Widgets, try clearing the web browser cache or checking it in a different browser. If the issue continues, please get in touch with Technical Support.
