There is heartbeat:anything RA which can be used to start any binary with any options and monitor by checking whether PID still exists; additionally you can add monitor hooks that allow you to do anything (e.g. check availability of website ...) > _Kamailio_ > > My idea was to let an ra send a SIP-request to kamailio and check, > if it gets an answer AND if it is the correct one. > > It seems like the ra > > https://github.com/ClusterLabs/resource-agents/blob/master/heartbeat/kamailio > > does exactly what I want, > but I do not really understand it.
