Hi, In the Kamailio OPENSER-MIB there is the counter "openserTotalNumFailedDialogSetups". This is a Counter32. The description is: "The total number of calls that failed with an error. The following codes define a failed call:" Question: * I'm looking for the corresponding counter to "openserTotalNumFailedDialogSetups" who counts successful Dialog setups of Counter32 type. Does it exist? * If not, does it exist a work around? * Where in the code can the new suggested counter be added? * Something else???? Suggestion for the new counter is a name like: "openserTotalNumSucceededDialogSetups". It has a counter32. Description: "The total number of calls that succeeded" 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. Rationale: 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. /Stefan PS. Ask if anything is unclear and I need an answer rapidly.
