@seang-es Any chance you can get me a sample log? (anonymized is ok). I'll write a test case for it and we can move forward with the fix.

(I'm open to merging the pattern fix first, btw, just want to get traction on me adding tests)

Sean opened this up from my ticket to ES support. An example log line:
<164>May 13 2015 11:56:41 asa-5510 : %ASA-4-106023: Deny tcp src dmz:192.168.xx.xx/xxxx dst pre:192.168.xx.xx/xxxx by access-group "dmz_access_in" [0x81470ed6, 0x0]
My change to the pattern:
$ diff -bur <(grep CISCO_TAGGED /opt/logstash/patterns/firewalls) <(grep CISCO_TAGGED /opt/logstash/patterns/sv)

The pattern is missing the space after the hostname match '?:' vs '? :'. Though allowing an optional space is likely better, we don't ship any messages without a hostname in our firewalls.

This is a duplicate of #2.
Also, I signed the CLA back in January, but the cla_check test is still failing because the work email address with which I signed the CLA is a secondary address on my github account. See comments on elastic/logstash#2102 for more detail.
