<div dir="ltr"><div><div>Hi,<br></div><br></div>If you use syslog-ng 3.10 you can give the cisco parser a try: <a href="https://www.balabit.com/sites/default/files/documents/syslog-ng-ose-latest-guides/en/syslog-ng-ose-guide-admin/html-single/index.html#cisco-parser">https://www.balabit.com/sites/default/files/documents/syslog-ng-ose-latest-guides/en/syslog-ng-ose-guide-admin/html-single/index.html#cisco-parser</a> It parses Cisco log messages (at least a good part of them) and creates name-value pairs from them.<br><div><br>If 3.10 is not an option for you, first I'd check if the PROGRAM macro really contains the information you are looking for. I usually do that using the format-json template with "--scope everything". It gives a lot more information than necessary, but still the quickest way to figure it out.<br><br>Or even better: use the Cisco parser for hints how to parse necessary information from logs. It is actually configuration snippet (SCL) and you can browse it on-line: <a href="https://github.com/balabit/syslog-ng/blob/master/scl/cisco/plugin.conf">https://github.com/balabit/syslog-ng/blob/master/scl/cisco/plugin.conf</a><br><br></div><div>Bye,<br></div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div>Peter Czanik (CzP) <<a href="mailto:peter.czanik@balabit.com" target="_blank">peter.czanik@balabit.com</a>><br>Balabit / syslog-ng upstream<br><a href="https://www.balabit.com/blog/author/peterczanik/" target="_blank">https://www.balabit.com/blog/author/peterczanik/</a><br><a href="https://twitter.com/PCzanik" target="_blank">https://twitter.com/PCzanik</a></div></div></div></div>

<p class="MsoNormal">Hello, <u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I’ve previously had a very simple regex list configured for Cisco ASA devices to deliver email alerts on routing changes in our network, which was configured thus:-
<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">filter f_sev1 { match("%ASA-3-622001"); };<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">…which works just fine. Wanting to expand this list a bit, and aware that scaling regex matching up is going to incur performance issues, I’ve thought that an “in-list” expression file might have been a better approach, and as such have
configured the following:- <u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">filter f_sev1 { in-list("/etc/syslog-ng/email-<wbr>match-list.list", value("PROGRAM")); };<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">…where “PROGRAM” is (I believe) the applicable part of the code that matches to the Cisco "%ASA-3-622001" part of the message. The whitelist has the following entries (as an example):-
<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">%DUAL-5-NBRCHANGE<u></u><u></u></p>
<p class="MsoNormal">%ASA-3-622001<u></u><u></u></p>
<p class="MsoNormal">%SPANTREE-5-TOPOTRAP<u></u><u></u></p>
<p class="MsoNormal">%SPANTREE-5-ROOTCHANGE<u></u><u></u></p>
<p class="MsoNormal">%ASA-5-111010<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I am not getting any matches here, however. What am I missing?<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Thanks very much in advance, <u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
