Hi 

from this log:

23:52:52.758 alex appinfo: Terminating due to signal: 1

 

How can I extract these item with rex:

user=alex

appname=appinfo

signal=1

 

Thanks,

Can you please try this?

YOUR_SEARCH| rex field=_raw "[0-9]{1,2}:[0-9]{1,2}:[0-9]{1,3}.[0-9]{1,3}\s(?<user>\w+)\s(?<appname>\w+).*signal\:\s(?<signal>.*)"

 

My Sample Search :

| makeresults |eval _raw="23:52:52.758 alex appinfo: Terminating due to signal: 1" | rex field=_raw "[0-9]{1,2}:[0-9]{1,2}:[0-9]{1,3}.[0-9]{1,3}\s(?<user>\w+)\s(?<appname>\w+).*signal\:\s(?<signal>.*)"

 

Thanks

it work separately but not work all in same time

Worked

rex field=_raw "[0-9]{1,2}:[0-9]{1,2}:[0-9]{1,3}.[0-9]{1,3}\s(?<user>\w+)
rex field=_raw "[0-9]{1,2}:[0-9]{1,2}:[0-9]{1,3}.[0-9]{1,3}\s(?<appname>\w+)
rex field=_raw "[0-9]{1,2}:[0-9]{1,2}:[0-9]{1,3}.[0-9]{1,3} .*signal\:\s(?<signal>.*)"

 

Not worked

| rex field=_raw "[0-9]{1,2}:[0-9]{1,2}:[0-9]{1,3}.[0-9]{1,3}\s(?<user>\w+)\s(?<appname>\w+).*signal\:\s(?<signal>.*)"

It's working for me on your given sample data. Can you please share those sample events which are not extracting?
