I used Kamailio and recommend using it sine it has the latest
commits for stability.<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>
Cheers,<br>

<br>
the dialog module counts the number of processed dialogs, see:<br>
<a moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://kamailio.org/docs/modules/stable/modules_k/dialog.html#id2966360">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>
