It may be worth mentioning there's a mod_snmp module for external monitoring. While that's also possible via ESL, XML RPC etc where it's better tested, SNMP at least allows integration with tools like Nagios. But as Eliot says, SNMP is slow and unwieldy and requires high timeouts. It's not something you're going to be able to use for failover. -Steve On 17 February 2013 22:51, Eliot Gable <egable+freeswitch@gmail.com> wrote:

This is just my two cents but could we not use snmp as a basis for something like this since it would allow monitoring eternally usiNng ones own systems, or allow each FreeSWITCH server to monitor the other servers over snmp. At least I think it could be an option to explore anyways.
SNMP is not intended as an HA solution. It is slow, and unwieldy to use. Fail over time using SNMP would be measured in minutes. We are going for sub-second fail over. SNMP is really only intended for external monitoring. SNMP also does not provide a solution for the vast majority of issues which an HA solution must cover.
