<div>Hi,</div>
<div> </div>
<div>In the Kamailio OPENSER-MIB there is the counter
"openserTotalNumFailedDialogSetups". This is a Counter32.</div>
<div>The description is:</div>
<div> "The total number of calls that failed with an
error. The following codes define a failed call:" </div>
<div> </div>
<div><b>Question:</b></div>
<ul style="margin-top: 0pt; margin-bottom: 0pt; margin-left:
19pt;">
<li>I'm looking for the corresponding counter to
"openserTotalNumFailedDialogSetups" who counts successful
Dialog setups of Counter32 type. Does it exist?</li>
<li>If not, does it exist a work around?</li>
<li>Where in the code can the new suggested counter be added?</li>
<li>Something else????</li>
</ul>

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">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>
