HI,

i've two datasources. Clearpass and Fortigate. I want to trigger an alarm if the Fortigate log contains Virus and Clearpass contains android. Is it possible in splunk to match those two based on src IP.

In similar use case, I created an alias for this field in props.conf under sourcetype stanza

[Clearpass sourcetype]

FIELDALIAS-ip_address =  ip_address as src_ip
