  • 1.  SBCE Traffic Monitoring

    Posted 01-14-2021 03:18 PM
    Avaya SBCE 7.2

    What is available to monitor SBCE traffic/load - call volume, available SIP paths, SBC load, bandwidth, etc.?

    Context:
    Some SIP is running on the SBCE - local inbound/outbound - but the volume is low. The decision is being made to increase outbound calling over the SBCE from a dialer. 150 SIP paths are available from the carrier. The SBCE has 200 available sessions (licenses). Without a set threshold, the dialer will use every available path/session to send out calls, even if the paths/sessions are increased to 2000 which is not going to happen anytime soon. There needs to be some available paths for local/long distance calling. 

    I need to be able to monitor the call volume to see if capacity is/will be reached.

    (TraceSBC/traceSM is not what I'm looking for.)


    Thanks,
    Ted

    Are you looking to monitor traffic in real-time, or via historical reports?  Is monitoring really what you are after, or do you actually want to constrain the numbers of calls?

    If you want just a snapshot in real-time, on the EMS, you can go into the EMS, go to the Status menu on the top, and then SIP Statistics.  You can drill down by Entity, Link, URI group, Policy and more.  There is an option to have the stats streamed (updated like every 30 seconds), but I've found it didn't reliably update  on versions prior to 8.0.  

    If you want basic reporting on the number of calls, you can export the CDR logs from the SBC and re-construct it.  In that report, you can get when calls start and end, so you can use something like PowerBI or Tablau to build reports showing the number of sessions in use at any given moment.  

    If you are looking to constrain the number of calls -- that gets a bit trickier.  The most sure-fire way I've been able to do this is via the SIP trunks in CM (if that is what you are routing your calls through).  You can build a trunk with certain number of members and route calls from your dialer via that.  In theory, you could setup CAC on System Manager / Session Manager to manage the number of calls for you (via bandwidth constraints), but the bandwidth won't come into play until after the call is setup, so if you have a dialer that is spitting out a ton of calls at the same time, it will easily oversubscribe you (since the CAC bandwidth will be 0 until the call is pinned up).

    Hi,

    there are some options.
    1. via the EMS GUI
    2. using CDR - you will need an CDR Tool
    3. Using SNMP

    I am using SNMP to query every minute the SBC to provide some statistics. I am using https://checkmk.com/ for that. And then CheckMK will send every week an pdf report with some graphs. You can use nagios or any other IT Monitoring Software with SNMP support for that.
