Hi @alex23,
You can extract only string in square brackets by using Grafana transformation Rename by regex. Please take a look at this post for more information:

Can you extract a word from within a tag to automatically label the legend?

Hi @ppxtb, In Transform tab (near Query) you can choose Rename by regex and for Match enter: .*\(([^\)]+).* and leave Replace as $1. [Grafana regex] Regex breakdown: .* - means any symbol 0 or more times (basically means match anything) \( - specifies that after anything there must be a literal symbol ( ( - starts matching group [^)]+ - means match anything until you find ) symbol ) - closes matching group .* - matches anything till the end Replace breakdown $1 - means return wha…

 

Regex that would do the job in your case would be:

.*\[([^\]]*)\].*

And in Replace field you would use $1.

 

Regex breakdown:
.*\[ - means match all till first literal symbol [
([^\]]*) - captures all strings that are inside square brackets. It matches everything till first ]. Mathed result is in group $1. Each time you specify round brackets () you get one more group (e.g $2, $3, $4…)
\].* - means tha there must be literal symbol ] and after that can be any number of any symbols

 

Tested on regex101:

regex101: build, test, and debug regex
