Hi friends,

I'm a newbie with grok filter and need help parsing the log message.

Here is my log message:  
**2016-07-11T23:56:42.000+00:00 INFO ALERT|ECE002|5 Error with transaction for session -464410bf-37bf-475a-afc0-498e0199f008**

I'm able to parse the message with following pattern:  
**%{TIMESTAMP\_ISO8601:timestamp} %{LOGLEVEL:log-level} %{GREEDYDATA:message}**

I need to parse **ALERT|ECE002|5** from message and get the value ECE002 from the message.

Is there a way to achieve that?

Cheers!

I would suggest using `csv` with `source => "message"` and `separator => "|"`
