Today our monitoring system threw up an error when trying to monitor the hardware status of a VMware ESXi host.
When going to the host’s hardware status in the VI client I was greeted with the error :
Hardware monitoring service on this host is not responding or not available

If this happens, SSH to the host and then restart the watchdog on the server. You can do this with the following command :
/etc/init.d/sfcbd-watchdog restart
You might get an error about no such process. If so issue the command :
/etc/init.d/sfcbd-watchdog start
Then follow it with a restart

Now go back to the hardware status tab and then click update.
