It may be worth mentioning there&#39;s a mod_snmp module for external monitoring. While that&#39;s also possible via ESL, XML RPC etc where it&#39;s better tested, SNMP at least allows integration with tools like Nagios.<div>

<p>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.</p>

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.</div>
