extract host name from field

[splunkuseradmin]

Hi everybody

I wanted to extract all hostname from this field "local_address" and save in a new field call "host" so that i only get the hostnames after "@"
I believe we can do it by "search | spath | rex field=local_address "@(?P[^-]+)"| stats count by _time host"
please corerct this.
below is the exact field

local_address

Hi,

You can try below search

<yourBaseSearch>
| spath
| rex field=local_address "\@(?<ext_host>[^\h]*)"
| stats count by ext_host,_time

If local_address is multi-valued field then you can try below query

<yourBaseSearch>
| spath
| rex field=local_address "\@(?<ext_host>[^\v]*)" max_match=0
| mvexpand ext_host
