Hello,

I tried to install the snmpstats module following this process :
I installed the dependencies for snmpstats module, then i modified modules.lst. 
Then i made a make modules, make, and make install.
Everything is fine so far.

After that, i edited kamailio.cfg the loadmodule for snmstats.so and when i launch kamailio I have the following error : "kamailio: ERROR: <core> [modparam.c:166]: set_mod_param_regex(): No module matching <snmpstats> found"

I also made a ldd :

Can you help me with this please ?

By the way I configured /etc/snmpd.conf by adding the line "master agentx" and created a file /etc/snmpstats.cfg with only one line : "agentXSocket tcp:localhost:705". Is that correct ?
Do i need to reload something after modifing those files ?
