How to extract words and digits from a particular field

majek81 — Thu, 14 Nov 2019 17:26:38 GMT

Hello everyone,

I am trying to extract strings containing SAMM #2222-A-1111 from other strings in a field named SAMU .
This is what I have entered:

SAMU="SAMM*" "#2*" "-*"

It works but also output other strings that I don't want to see.
Any suggestions?

I have two thoughts:

1) You can try double searching on SAMU, like so:
SAMU="SAMM*" SAMU="*#2222-A-1111*" (not the best)

2) Use regex:
| makeresults count=3 | streamstats count | eval fieldToAlertOn=case(count=1, "potato SAMM potato potato #2222-A-1111 potato", count=2, "SAMM #3333-A-1111", count=3, "potato SAM potato #2222") | regex fieldToAlertOn=".*(?SAMM).*(?\#2222-A-1111).*"

If you run this you can see that only the row with both of those values sticks around. Also not the cleanest solution, but you can be more selective with what you're allowing if you're more familiar with regex (changing specific numbers to number characters, etc).

Wow awesome code, it didn't quite give me the result I wanted but it does have some other use-cases.
Perhaps a little simplistic, but this is what work for me
sourcetype=some_sourcetype |mvexpand SAMU| search SAMU="SAMM*" " #20*" "-*"
