Good evening,
I'm quite new in the Kamailio community so at the beginning I just want to say
"Hello" to everyone.
I have a following problem with SNMP in Kamailio.
I want to collect data from Kamailio by SNMP. I've installed snmpd on the machine
(Linux RHEL) and it's working. I've load snmpstats module in Kamailio and it
starts up without error. I've configured Kamailio to use agentXsocket and enable
agentx in SNMP. Port 705 is opened and netstat shows connection established between
Kamailio and SNMP. Wireshark shows some packets going through. The problem is that there
is no data during snmpwalk from Kamailio. Just standard data from SNMP, nothing from
Kamailio. I've copied Kamailio MIBs to the proper directory, added it in the
snmp.conf. Moreover I've tried to add -m +KAMAILIO-REG-MIB to snmpwalk. Still no data
from Kamailio during snmpwalk.
Any ideas?
Best Regards,
Michal Muszalski

New subject: Session Timers Problem
Our Kamailio statefully forwards requests to our Asterisk cluster.
Sip session timers fail, whether our Asterisk servers are UAS or UAC.
Kamailio receives the re(INVITE), and just dispatches it out using the default algorithm.
I see the record-route header, so I'm not sure what else is missing..
(aside from the last sip packet showing the packet dispatched to a new asterisk peer)
Anybody have some troubleshooting tips for us?
Loose_route should match the transaction based on record-route, is my understanding.
Same thing happens whether carrier re(INVITE)'s or Asterisk does. Just gets dispatched
to the next peer in the list.

Hello,
if you start snmp daemon in debug mode, do you see references to
kamailio MIBS?
On some systems, the paths are different, I remember that I had to move
in various locations in order to get the MIBS properly seen.
Cheers,
Daniel
