Our Grafana instance was set up by someone who has since moved on to other employment. One of the panels we use in multiple dashboards is monitoring the CPU usage of the ESXi hosts in our vSphere cluster. We’ve just completed migrating our VMs to a new cluster, and I’m trying to figure out how to update Grafana to point to the new cluster instead of the old.
The only place I can see a reference to vCenter in our configs is in /etc/telegraf/telegraf.d/vcenter.conf - I changed the hostname there to point to the new cluster, and rebooted everything. But I’m still getting data from the old vCenter cluster on the dashboard, which really makes no sense to me.
Since I didn’t have a hand in setting this up originally, I’m sort of trying to reverse-engineer what we’ve got set up. Hoping someone might be able to point me in the right direction. We’re on Grafana 7.0.0.
