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:

 

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:

So thanks . also I want to remove “MDS9706-1: Input Traffic” for follow string

MDS9706-1: Input Traffic fc1/12 - HOST12-HBA2

but in the regex101 site cannot set regular expression as we don’t have any symbols such as () {}

Hi @alex23,
You can use this regex:

MDS9706-1: Input Traffic(.*)

or maybe this regex which is a bit more flexible:

[^:]*: Input Traffic(.*)

Second regex allows that you can have any string instead of MDS9706-1. It requies : colon symbol and strings Input Traffic and anything after those strings will be matched in group $1. Example: Regex101.
