. It is very unlikely to backport new features in stable branches,
however, when the patch will be done for devel branch should work
also on 3.1.x since there were no other changes in devel vs 3.1.<br>

... ^^^ ... obviously this was incomplete phrase, it meant to be:
"I used Kamailio 3.1.2 and recommend using it since it has the
latest commits for stability".<br>
<br>
I can add also that I got more familiar in configuring it with
snmpstats on debian/ubuntu, so it would be easier for me to give
hints as well as add new features since it is the same as devel
version.<br>
<br>

However, what I wrote before is pretty much not related to the
version. There is a counter that tracks the processed dialogs,
but seems it is not exported by default through snmpstats
module. The statistics counter is named "processed_dialogs",
implemented by dialog module.<br>
<br>
You can dump all internal statistics through kamctl or via
xmlrpc command, but probably to export it through snmpstats you
may need to extend the mibs and the code of the module.<br>
<br>
I just grepped the sources of snmpstats module to see what
dialog statistics it is exporting:<br>
<br>
$ grep -n _dialogs modules_k/snmpstats/* | grep get_statistic<br>
modules_k/snmpstats/alarm_checks.c:83: num_dialogs =
get_statistic("active_dialogs");<br>
modules_k/snmpstats/snmpObjects.c:404: int result =
get_statistic("active_dialogs");<br>
modules_k/snmpstats/snmpObjects.c:424:
get_statistic("active_dialogs") -<br>
modules_k/snmpstats/snmpObjects.c:425:
get_statistic("early_dialogs");<br>
modules_k/snmpstats/snmpObjects.c:443: int result =
get_statistic("early_dialogs");<br>
modules_k/snmpstats/snmpObjects.c:459: int result =
get_statistic("failed_dialogs");<br>
modules_k/snmpstats/snmpObjects.c:508: int num_dialogs =
get_statistic("active_dialogs");<br>
<br>
Perhaps when the snmpstats was developed the dialog module
didn't export the statistics counter of "processed_dialogs" and
then it was not updated.<br>
<br>
Now, what I tried to say is that if the "processed_dialogs"
counter is not available through snmpstats (and it is not now
after grepping the sources) you can get its value from another
application through "kamctl get_statistics all" or XMLRPC
command for all of the existing kamailio releases. Upcoming one
we will look to implement the export through snmpstats as well.
If you have time to do it and send us a patch, we will gladly
commit it to source tree in our GIT repository.<br>
<br>

<br>
the dialog module counts the number of processed dialogs, see:<br>
<a class="moz-txt-link-freetext"
href="http://kamailio.org/docs/modules/stable/modules_k/dialog.html#id2966360"
moz-do-not-send="true">http://kamailio.org/docs/modules/stable/modules_k/dialog.html#id2966360</a><br>
<br>
There is no counter currently inside dialog module exporting
exactly the number of successfully setup dialogs, it should
not be hard to do it, though. Using the above and the number
of failed and expired dialogs, you can actually get the number
of successful dialogs.<br>
<br>
Dialog module being the one that tracks SIP dialogs, therefore
being able to count them, now I don't know if snmpstats module
exports all the counters from dialog module. I setup snmpstats
just few weeks ago and works perfect on Ubuntu/Debian servers,
but I had no need to check dialog module counters.<br>
<br>
Note that you can get the list of all internal statistics via
kamctl:<br>
- kamctl fifo get_statistics all<br>
<br>
Or via XMLRPC if you need them remotely in another
application.<br>
<br>
Another option is to define your statistics with statistics
module. Knowing that in SIP a successful call dialog means
200ok reply to an INVITE transaction, you can count it in the
onreply_route[abc] that you arm for relayed transactions with
t_on_reply("abc").<br>
<br>
Hope these help you,<br>

<div>Suggestion for the new counter is a name like:
"openserTotalNumSucceededDialogSetups". It has a
counter32. Description: "The total number of calls that
succeeded" </div>
<div> </div>
<div>I know that there are the counters
openserCurNumDialogs, openserCurNumDialogsInProgress and
openserCurNumDialogsInSetup but these are of Gauge type
who only reflects the current situation. These Gauge
counters can't be used together with a Counter32
counter. That don't mix. The calculation done for the
counter "openserCurNumDialogsInProgress" should be used
where every new dialog setup is added to the new
suggested counter. A counter of 32 should cover a great
deal of connections. These counters are usually read, if
used, every 15 minutes or 1 hour.</div>
<div> </div>
<div> </div>
<div><b>Rationale:</b></div>
<div>The reason for the new counter is that a calculation
between succeeded and failed dialog setups can be done
and be used for SLA agreements. Without this, its hard
to make any customer versus provider agreements.</div>
