Host resource counter on summary page not visible

On a production at one of customer sites showed blank on host resources,

The host was already added to the cluster...

To resolve the issue,

• Enabled the SSH service on the host.
• Connected through a putty session.
• Restarted the management services using "services.sh restart" command.

Host automatically got disconnected. Connected the host back again and voila! there it was with all the counters visible.
