I have a simple dashboard that pulls a hostname as a variable from an Elastic Index. This used to work on Elastic 6.7, but i’ve had a number of issues since upgrading to 7.1. I’ve upgraded Grafana to 6.3.0 and my datasource looks ok. It gets Index OK, Time field name OK when I save and test it.
My problem now is that the variables on the dashboard don’t find any results. There is no error.
If I hardcode the vsphere.host.name into a panel then it works as expected (i.e. it finds the value and displays it correctly on the graph.)
Here is some example data from within the specified index.
Can anyone explain why the variable preview finds no values? Has the syntax changed or have I missed something obvious!?
