Reporting

Why are reports no longer working and how to segregate syslog data by IP address (firewall)?

hi all,

we are currently monitoring few firewalls and picking up the data from syslog (514).

I used to have this search running beautifully:

sourcetype="cisco:asa" action="blocked"| stats count as Count by src_ip | rename src_ip as "Source IP" | rename dest_ip as "Destination IP" | sort -Count

However, now everything seems to be coming from sourcetype syslog

My questions are:

1) Why has this (sourcetype="cisco:asa" ) stopped working?
2) How do I segregate the data coming from Syslog by IP address (firewall) and filter the events I want (e.g.: 106023)

Any comments are appreciated

the issue is that sourcetype="cisco:asa" was working fine until 19 Jan....Then my colleague run the following in the firewall:

User 'enable_15', running 'CLI' from IP <> executed 'logging host inside <> format emblem'

from then the sourcetype became "syslog"

Not sure about your first question but if you can't get your sourcetype working, could you use the host field to identify which firewall/ip is forwarding the events? And then filter out events as per http://docs.splunk.com/Documentation/Splunk/6.2.1/Forwarding/Routeandfilterdatad
