Re: [SR-Users] Failover with UCARP and Monit

Hello, I am setting up a high-availablilty kamailio system using UCARP to failover between active and standby instances. To detect failure, we intend to use Monit. Monit can monitor the kamailio PID and start the process when needed (Example on the wiki http://www.kamailio.org/dokuwiki/doku.php/install:configure-initd-script) and it can also do OPTIONS pings to verify it is working. If the pings fail we will initiate a ucarp swap.

However if the server is currently in standby, it does not have the V-IP address, so I don't want to run the OPTIONS pings (I think).

So, do not monitor a service which is not running.

Such things are usually done by a cluster resource manager (like pacemaker).
