[sr-dev] SNMPstats additions

[Sebastian]

Hi,

I'm trying to expand the snmpstats module as well:). My client demands some 
info about active dialogs.
Glad to see this module being picked up again. For snmp table, Have you 
checked the tutorials on the site
of net-snmp, it's a good place to start.

Hi!

For some weird reason I decided to make the SNMPstats module a bit more 
useful and started adding new data to it, in order to learn how to work with 
net-snmp and try to learn where to find the data.

Here's some new entries in the Kamailio MIB:

Memory data:
===========

KAMAILIO-MIB::kamailioSrvMaxMemory.0 = Gauge32: 33554432
KAMAILIO-MIB::kamailioSrvFreeMemory.0 = Gauge32: 31709088

Version data:
===========

KAMAILIO-MIB::kamailioSrvCnfFullVersion.0 = STRING: kamailio 4.0.0 
(i386/linux) 50af49
KAMAILIO-MIB::kamailioSrvCnfVerName.0 = STRING: kamailio
KAMAILIO-MIB::kamailioSrvCnfVerVersion.0 = STRING: 4.0.0
KAMAILIO-MIB::kamailioSrvCnfVerArch.0 = STRING: i386
KAMAILIO-MIB::kamailioSrvCnfVerOs.0 = STRING: linux
KAMAILIO-MIB::kamailioSrvCnfVerId.0 = STRING: 50af49
KAMAILIO-MIB::kamailioSrvCnfVerCompTime.0 = STRING: 12:12:27 Mar 24 2013
KAMAILIO-MIB::kamailioSrvCnfVerCompiler.0 = STRING: gcc 4.1.2
KAMAILIO-MIB::kamailioSrvCnfVerFlags.0 = STRING: STATS: Off, USE_IPV6, 
USE_TCP, USE_TLS, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, 
DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, USE_FUTEX, 
FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, 
USE_DST_BLACKLIST, HAVE_RESOLV_RES


TCP Statistics and configuration data:
==============================

KAMAILIO-MIB::kamailioNetTcpConnEstablished.0 = Counter32: 0
KAMAILIO-MIB::kamailioNetTcpConnFailed.0 = Counter32: 0
KAMAILIO-MIB::kamailioNetTcpConnReset.0 = Counter32: 0
KAMAILIO-MIB::kamailioNetTcpConnSuccess.0 = Counter32: 0
KAMAILIO-MIB::kamailioNetTcpConnOpened.0 = Gauge32: 0
KAMAILIO-MIB::kamailioNetTcpConnPassiveOpen.0 = Counter32: 0
KAMAILIO-MIB::kamailioNetTcpConnReject.0 = Counter32: 0
KAMAILIO-MIB::kamailioNetTcpEnabled.0 = INTEGER: true(1)
KAMAILIO-MIB::kamailioNetTcpMaxConns.0 = INTEGER: 2048
KAMAILIO-MIB::kamailioNetTcpAsync.0 = INTEGER: true(1)

The version part is complete, but TCP and memory can be expanded to cover at 
least the same
data as we can get from the RPC interface.

I would like to be able to list process memory data in a table so one can 
monitor both core and process memory using SNMP. In order to do that, I need 
to figure out how to create SNMP tables :-)

It would also be nice to be able to expose some private counters from the 
configuration script,
like "number of vulcan language messages" and "MESSAGE requests in Klingon".

Any comments, ideas?
