Hello,

Not sure if this is really the problem, but one thing I noticed:

You want to operate a stateless server but configured dialog values in the module. This will not work (according to the documentation) without the dialog module, which will not work on a stateless server.

Try to remove the dialog values.

Cheers,

Henning

Subject: [SR-Users] SNMP setup

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,
