I want to change the color of cell according to the status ,here its “PASSED”
After “,” there can be any other string.
Example - PASSED, BLD_POLARIS_DEV_LATEST_20230524_015103
Is my regex correct?

Hi @dakshagarwal886,

Thanks for opening this post.

I am also not a wizard with regex :slight_smile: but try to put a dot “.” i.e.

^.(PASSED).*$

I tested this one using the regex101 website.

Grafana actually uses Go programming language for the backend and to parse the Regex need also to be in the same flavor.

I hope this helps.

Hey @usman.ahmad
So I’m using it on a field I created using transform (all values in a matrix) on two fields
I am using the new transformed as value in my esnet matrix
I want the square to show status color according to the first element (example - “PASSED”, “STOPPED”,… etc)
I tried your regex but its reflecting into the esnet matrix
Can you suggest some other way?

I would need either access to your Dashboard to view it and try it out

OR

You need to provide the step-by-step instructions so that can also try to reproduce it on a test machine?

Thanks.

I have two field as
Field 1 : State which conatins “PASSED”,“FAILED”,…etc
Field 2 : Labels like “BLD_POLARIS_DEV_LATEST_20230524_015103”,…etc
I am using transfrom for these two fields

  • ADD field for calculation
  • Mode - Reduce Rows
  • calculation - All Values
    This creates a ALL Values field
    I am using that in Value for esnet matrix
    where X n Y axis are other 2 fields
    Can I show Color according to State like"PASSED" is green

So normally you can but your use-case involves transformations.

Can you please try to reproduce this same issue on https://play.grafana.org/ and then share the dashboard link so that we can view it?

Asking again because its more easier to view it as I simply cannot recreate first and then reproduce it with your above steps

Thanks
