Hi all, I've created a Munin plugin to monitor the number of dialogs in Kamailio:  http://dev.sipdoc.net/wiki/sip-stuff/KamailioMuninPlugin

Hope it's useful. Suggestions are welcome.

thanks, looks good. Seems to be straightforward to add other graphs.

Which other graphs would you suggest? Note that it must be a realtime value (most of the statistics reported by "fifo get_statistics" are the absolute value instead of realtime value).

Maybe ability to use it over net (mi_datagram) would be interesting.

However, usuarlly munin-node runs on each monitored host since existing plugins require to run in localhost (cpu, mem, disk, process...).

used shared memory, active transactions could be some examples.

Shared memory is realtime value so I will create a new Munin plugin for it.

But active transactions is an absolute value (it's the sum of all the transactions since Kamailio started):

tm:received_replies = 1864986 tm:relayed_replies = 1165061 tm:local_replies = 696721 tm:UAS_transactions = 878280 tm:UAC_transactions = 0 tm:2xx_transactions = 536636 tm:3xx_transactions = 0 tm:4xx_transactions = 321816 tm:5xx_transactions = 19804 tm:6xx_transactions = 59 tm:inuse_transactions = 63

inuse_transactions (what i meant by active transaction) is realtime.

opss, right!

Ok, I'll add it.

Hi, I've added active transactions and shared memory usage monitor: http://dev.sipdoc.net/wiki/sip-stuff/KamailioMuninPlugin

BTW: which is the difference between shmem_used and shmem_real_used?

shmem_used does not account for internal memory management overhead, while shm_real_used does.

Want to just add here that I just started using it, really good to monitor usage in a very simple way. It was 10 minutes work to get running, much easier than other methods I've been looking at to monitor current usage.

Thanks!

Hi Alex,

Can't one get this information into any SNMP NMS and/or graphing utility just by querying openserCurNumDialogs.0 in the OPENSER-MIB (via the SMPStats subagent?). I use this a _lot_.

Sure. But if you are (like me) already using Munin and don't have a SNMP setup on the machines yet, it's quite practical to write some plugins for munin like this. It's actually just a script, but it's pretty smart to think of it. :)

I just always favour using the most generic and reusable mechanisms possible on which to build application-specific extensions. In other words, this module strikes me as a "leaky abstraction."

Sure using SNMP is a more standard way, but Munin does exist and it's very extended (useful and very easy to configure) :)
