grouping search results by hostname

We need to group hosts by naming convention in search results so for example hostnames:
x80* = env1
y20* = prod
L* = test
etc..

Also can this be done by | tsats command?

Try this

... | eval env=case(match(host, "x80*), "env1", match(host, "y20*), "prod", match(host, "L*), "test", 1=1, "UNK")

Try something like this (sample tstats command, replace it with your own). The case statement works with regular expression and providing a partial regex will match any position.

| tstats count WHERE index=* by host | eval Environment=case(match(host,"x80"),"env1",match(host,"y20"),"prod",match(host,"L"),"test","ny","someotherenv",ture(),"OTHERE") | stats sum(count) as count by Environment

Thanks, looking promising. seems to struggle with hosts matching names in the middle so like ny

This will look for hosts that start with x80 for eg. Not in the middle. Can you share some sample or mocked up hosts to adjust the match pattern

ah the page does not like the wild cards. common is the ny between the wildcards * ny *
RAAG14*NY1234
RABHAG94
NY1256
RACAG84
NY1277
RADAGSS4
NY1244
RAEAG14
NY*9888

page keeps cutting my post, but i hope it makes sense..

So all hosts with the characters NY should be considered in the prod group?

Try these

match(host, "\*")

match(host, "NY")
