The problem I faced with this approach is when the syslog-ng triggers
the program, it memorizes that. So calling rancid-run script directly
doesn't work. You need a wrapper script for this directive to work.

<pre wrap="">Hello everyone;
I implemented the solution with the following syslog-ng modification and a script in perl. When the syslog receive a change configuration trap trigger the script. You should adapt it to your specific system. In this case the syslog translate the IP add from the hosts/DNS and I use that name. also I put the script in the log directory to avoid permit issues. Hopefully It will work for you.
Syslog.conf:
source net { udp(); };
filter f_change{ match("SYS-5-CONFIG_I: Configured"); };
destination df_change { program("perl /var/log/rancid.pl"
template("$HOST\n") );
};
log { source(net); filter(f_change); destination(df_change); };

Subject: [rancid] Re: Rancid and Syslog-ng
Another option I use is snmptt. There's an SNMP trap an IOS router can
send upon config change, and I use snmptt to run rancid against that
host when it receives such a trap.

<pre wrap="">Guys,
Has anyone ever been successful with setting up rancid and syslog-ng so that
whenever a config change is written to memory, syslog-ng calls the rancid
executable for that host only?
Basically we're looking to have rancid query a device only when that
device's configuration has been modified.
