I am new to Grafana and currently working on building a dashboard. I am facing an issue during that process.
For example, assume we have four data sources (v1_e1,v1_e2,v2_e1,v2_e2). The data sources have to selected based on two variables ‘v’ and ‘e’. The variable ‘v’ can take two values v1 and v2. The variable ‘e’ can take two values e1 and e2.
Now, I want to select the data source based on combination of values from these two variables. I tried to do that using regex expression by could not succeed. Can any of you help me in how to solve this issue. Thanks.
