Hi all!
I am having difficulties setting up SNMP, and mostly to figure out if what
I have setup is correctly configured.
This is what I have on Kamailio (5.8.2), which is set as stateless and as a
redirect server (simply put, it receives INVITE from SBC, gets a route from
routing services, modifies Contact header, and replies to SBC with 300
Multi Choice with new contact header):
loadmodule "db_mysql.so"
loadmodule "db_cluster.so"
loadmodule "http_client.so"
loadmodule "jsonrpcs.so"
loadmodule "kex.so"
loadmodule "corex.so"
loadmodule "sl.so"
loadmodule "pv.so"
loadmodule "maxfwd.so"
loadmodule "textops.so"
loadmodule "xlog.so"
loadmodule "sanity.so"
loadmodule "jansson.so"
loadmodule "snmpstats.so"
loadmodule "file_out.so"
loadmodule "ctl.so"
loadmodule "permissions.so"
loadmodule "xhttp.so"
loadmodule "xhttp_rpc.so"
# ---- SNMP Stats params ----
modparam("snmpstats", "sipEntityType", "proxyServer")
modparam("snmpstats", "sipEntityType", "redirectServer")
modparam("snmpstats", "sipEntityType", "other")
modparam("snmpstats", "snmpgetPath", "/usr/bin/")
modparam("snmpstats", "MsgQueueMinorThreshold", 1)
modparam("snmpstats", "MsgQueueMajorThreshold", 1)
modparam("snmpstats", "dlg_minor_threshold", 1)
modparam("snmpstats", "dlg_major_threshold", 1)
modparam("snmpstats", "snmpCommunity", "kamailio")
I have set the *_minor_threshold values to bear minimum. Should I add
anything else?
The logs show the following messages:

The SNMP daemon is set as follows:

agentaddress udp:161
rocommunity kamailio
master agentx
agentXSocket tcp:localhost:705
trap2sink 10.X.Y.Z netcool 162
When running tcpdump and listening on port 162, no traffic is
captured....it seems to me that Kamailio is not sending anything to SNMP
Any clue, anyone? What am I doing wrong?
Atenciosamente / Kind Regards / Cordialement / Un saludo,
