Grok stop at the first occurrancy error

[rschirin (Robert)]

hi,
I'm trying to get a specific username using grok plugin.
this is my message:

and this is my grok function:

.*user\s%{GREEDYDATA:username.start}\",\"Running\sas\s%{GREEDYDATA:username.running_as}\",\"

username.start is extracted correctly while username.running_as is wrong (Michael Jordan","Obtained Deploy/Jenkinsfile from....)

can you explain where am I fault?

@rschirin

can you explain where am I fault?

GREEDYDATA is just that, greedy. It will match the longest possible string. So if you match A%{GREEDYDATA:a}B against A...B...C...B it will not match ..., it will match ...B...C...

You could change the second GREEDYDATA to be DATA, but I think you would do much better with a pattern like

'Started by user (?<username.start>[^"]+)","Running as (?<username.running>[^"]+)"'

Also, the .* at the beginning in your pattern is meaningless since the pattern is not anchored.
