Subsearch Help

[richardphung]

I have the following search:

index="*" sourcetype=endpoints [search index="*" signature="sig_id" | dedup dest | fields dest ]

Which produces no results.

Doing each of these, independently works...
For example, the subsearch:

index="*" signature="sig_id" | dedup dest | fields dest

gives me a nice stats table with hostname_1, hostname_2, etc.

And if I manually define this in the main search:

 index="*" sourcetype=endpoints hostname_1

I get all of my events.

Hi guys, I hope I can borrow your fantastic brains on this one, I have the same concept, I want to check the top failed ip that authenticated afterwards:

<search_for_authenticated_users> ip [<search_for_failed_user>| top limit=100 client_ip | rename clientip AS ip | table ip ] | top  user ip

I hope someone can shed some light, or direct me somewhere where some else has faced the same problem.

You should always use | format at the end of your subsearch so that you can see what it is creating. If you had done so, you would have seen that your subsearch is using the field name in the SPL that it generates (like dest="value"). Based on your test search, you need just the value so try this:

index="*" sourcetype=endpoints [search index="*" signature="sig_id" | dedup dest | fields dest | format "(" "" "" "" "OR" ")" | rex field=search mode=sed "s/dest=//g"]

This is a great tip.

Figured it out...
the field dest doesn't exist in the main search.. need to rename field:

index="*" sourcetype=endpoints [search index="*" signature="sig_id"  | dedup dest 
    | rename dest AS client_name | table client_name]

It is OK to keep the | format in your search, like this:

index="*" sourcetype=endpoints [ search index="*" signature="sig_id"  | dedup dest | rename dest AS client_name | table client_name | format ]

So your subsearch produces a field named "dest". Is there a "dest" field (containing hostname_1, hostname_2, etc.) available in the primary search?
