Resolution

This is an expected behavior in VMware vRealize Operations Manager.

The possibility of vSphere Distributed Switch Port Groups to be transitory in nature can lead to an excessive number of irrelevant metrics being collected and persisted in vRealize Operations Manager. All instance level Network|Port Statistics metrics are excluded by default, to help mitigate this potential behavior.

 

To enable the collection of all metrics:

1. Log in to the master node as the admin user.
2. Make a copy of the current exclusionlist.txt file by running this command: :

cp $ALIVE_BASE/user/plugins/inbound/vmwarevi_adapter3/conf/exclusionlist.txt /tmp/exclusionlist.txt.$(date +%F)

1. Open the $ALIVE_BASE/user/plugins/inbound/vmwarevi_adapter3/conf/exclusionlist.txt file in a text editor.
2. Comment out the line that reads:

LWDistributedVirtualPortgroup|network|port_statistics|*::-

1. Save and close the file.
2. Repeat steps 1 to 5 on all other nodes in the cluster.
3. Log in to the vRealize Operations Manager Admin UI.
4. Click Take Offline.
5. After the cluster is offline, click Bring Online.
