Kibana: extract fields, ad-hoc?


(Brice Ruth) #1

Good morning.

Newbie Kibana/elasticsearch/fluentd user here. Long-time Splunk power-user.
One of the things I find myself doing all the time in Splunk is working
with ultimately unstructured data and, as I need to, extracting a field
from search events matching my current search so I can subsequently chart
that field or do something interesting with it. For example:

invalid_session | rex "ID: (?<msg_id>.*)" | stats dc(msg_id) by host

So, here I'm using the "rex" command to ad-hoc extract a "msg_id" field
which I can subsequently use in another command (here, counting the
distinct msg_id by host).

Is there any way to do this with Kibana? This is hugely valuable when
day-in/day-out you're dealing with unstructured data of one sort or another
(too many to setup field extractions for!).

Thanks in advance!
Brice Ruth

Hello Brice,

I think that, for now, the best way to go is to use something like Logstash
to extract fields from unstructured data at index time. I'm not aware of a
way to do that at query time.

Best regards,
Radu

Thanks for the response! I think this is an important feature to get on the
roadmap, architecturally. It's massively useful when processing
unstructured data.

Thanks!

Would it be possible to write some type of plugin to extract the relevant
fields afterwards?
To write filters for logstash that catch every possible emailpattern
beforehand is not that easy.
