Dear team, I am trying to add a panel in my dashboard which give me back the time duration for my test. i am very new to grafana.
I am trying to plot time duration (difference between start time and end time), this should be a single panel displaying time duration. The data source i have is elastic and my test sends data during the test, i am trying to display the test duration by subtracting final timestamp (from metrics) with the first timestamp. any inputs here would be helpful
