Add Percentage Free column to table panel

  • 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   6 TB   10 TB

We would like it to be:

           ESX   Free   Total   %Free   6 TB   10 TB   60%

Tried different solutions on the forum but none actually worked for us.

What is your data source. Best to do it on the datasource itself otherwise it will get very hairy using transformation.


I tried your transform solution an that turned out to be very acceptable in our environment.
May not be the prettiest option but it is functional and that’s whats our main concern is.

Thank you for the assistance.
