Hi asterisk and ser users,
Is there a solution to monitor asterisk and ser with
snmp ?

Hi Harry,
ser does not support SNMP. There is a module, but it has not been
maintained for ages and does not work.

As answered, no.
What i did to monitor ser and sems was to create bash scripts which
restart ser and/or sems in case of failure.
For ser, the script sends fake REGISTER messages (with expires=0). If
the answer is 200 OK (or a 40x proxy authenticate) ... then ser is
alive. If nothing is read, then i restart ser.
For sems, i tried two approaches.
- active: send a specially crafted message (INVITE) so that you know
for sure that ser will route it to SEMS ... depending on the answer,
you should be able to know wether SEMS is alive or not ... but this
has a problem (see below for a larger explanation).
- passively: start sems so it writes its PID to a log file ... then
monitor (using ps aux) that pid ...if not there, restart SEMS.
- i seem to remember someone mentioned a status module for sems, which
would allow you to send commands via the fifo/unixsock interface, and
check actively sems (including activity statistics) ... is this true?
===== ACTIVE MONITORING PROBLEM
What i tried to do is to created unique INVITE messages, which i make
sure that ser routes to sems. They had unique call-ids and to/from
tags ... thus theoretically ser should see them as independendent
requests.
But, if sent these INV requests too often (that is, less than a minute
or so ... time enough for the transaction to be destroyed in ser mem,
i guess ... ), ser would mistakenly think they were retransmissions
...
It would also start acting weird and sending replies to the wrong port ...
This is why i went to passive monitoring ... i do not have time to
investigate any further ... but i can provide the script for someone
else to try ...
BTW, i use ser 0.9.6

Cesc

As others have noted SER does not directly support SNMP but you can
easily enhance your snmpd to support it.
You add serctl fifo commands using the snmp exec directive
to monitor the number of users, transactions stuff, ...
The meminfo patch (now included) is handy and you can directly pipe
serctl fifo meminfo into SNMP and create nifty graphs.
sipsak comes in handy, i.e. sending an OPTIONS request and measuring
a) if a response comes back and b) the time processing took.
Much better would be monitoring INVITE/REGISTER response behaviour since
that usually requires a whole lot more interaction (radius, db, ..)
on SER side.

Hello Hendrik,
What about VRRP for failover ?
SER1 (master)
sip agents == || === Asterisk Farm==sip/pstn gateway
SER2 (slave)
