What Grafana version and what operating system are you using?
9.4.7 on windows
What are you trying to achieve?
We have a dashboard showing the ip of an ESX server the free space on the datastore an the size of the datastore. Would like to add a column showing free as a percentage.
As an example we now have:
ESX Free Total
192.168.100.54 6 TB 10 TB
We would like it to be:
ESX Free Total %Free
192.168.100.54 6 TB 10 TB 60%
Tried different solutions on the forum but none actually worked for us.
