Splunk for Asset Discovery: How to fix search syntax for port signatures panel?

the port signatures panel of the port overview dashboard is not working
The search string is:

eventtype=port_scan "Linux 2.6.32 - 3.10" | stats dc(dest_ip) as count by port_signature | where match(port_signature, replace(replace(""Linux 2.6.32 - 3.10"", "\s*OR\s*", "|"), "*", ".*")) | sort - count

The error is:

Error in 'where' command: The expression is malformed. Expected LIKE.

I get the problem just can't work out where to put the LIKE

Anyone?

Kind Regards
Peter

The problem is in your second "replace()" call. The "Linux 2.6.32 - 3.10" term should only be contained in a single set of double-quotes, not two sets.

What you have:

eventtype=port_scan "Linux 2.6.32 - 3.10" | stats dc(dest_ip) as count by port_signature | where match(port_signature, 
replace(replace(""Linux 2.6.32 - 3.10"", "\s*OR\s*", "|"), "\*", ".*")) | sort - count

What it should be:

eventtype=port_scan "Linux 2.6.32 - 3.10" | stats dc(dest_ip) as count by port_signature | where match(port_signature, 
replace(replace("Linux 2.6.32 - 3.10", "\s*OR\s*", "|"), "\*", ".*")) | sort - count
