here is a short snippet from kamailio debug logs:

if i do an snmpwalk or snmpget,

snmpget -c VOIP -v 2c localhost .1.3.6.1.4.1.34352

SNMPv2-SMI::enterprises.34352 = No Such Object available on this agent at this OID

snmpwalk -c VOIP -v 2c localhost .1.3.6.1.4.1.34352

SNMPv2-SMI::enterprises.34352 = No Such Object available on this agent at this OID

i cannot see any other debug messages in kamailio when i do an snmpwalk or snmpget. 

something is so screwed up here. can't seem to find it.

I will look more into it soon -- I was offline for several days.

let me take this opportunity to also share this patch to avoid the dreaded undefined symbol: EVP_DigestInit

problem when compiling. 

apparently, 

             BUILDAGENTLIBS = $(shell net-snmp-config --netsnmp-agent-libs)

is not enough because net-snmp external libraries aren't linked properly without implicitly stating it in the Makefile

so i added this line after it:

             BUILDAGENTLIBS += $(shell net-snmp-config --external-libs)

*this is assuming net-snmp is built without perl. (or i think even if built with perl, this additional line will fix it)

So both are needed, right? There was a discussion about missing symbols after linking, probably this will fix it better.

Thanks,
Daniel

hi guys,

anybody here tried using snmpstats with 3.0.0?

yes, before release there was quite some activity around this module.

i keep on getting "No such Object"

already verified that kamailio is talking to agentx master.
net-snmp version 5.3.3 compiled from source
also disabled openssl and md5 in net-snmp to prevent any undefined symbols

been reading the mailing lists and so far nothing helped. seems like only a couple of guys
are using this module?

I am not really using it production wise, but if you can post here syslog messages of the error and other details that you can grab, I might be able to help.

Cheers,
Daniel
