    Hi,

     

    We recently upgraded nas version and post which we have nas probe down. On checking the logs I can see

     

    May 19 10:03:00:403 [10288] nas: Subscriber destroyed...

    May 19 10:03:00:419 [10288] nas: Destroying NameService...

     

     

    What these messages signify and what is a way to restore services. We even tried to downgrade the version which again shows the same error.

     

    Thanks,

    did you deactivate and re activate the probe otherwise maybe a restart of the hub would work.

    Hi Neal,

    Thanks for the update. I managed to bring the probe up and running. It was down because of alarm_enrichment as we are not using it in our environment. But I would still be interested in knowing the significance of the log messages generated.
    Thanks again.

    Thanks,

    Makes sense nas needs alarm_enrichment as it initially excepts the alarm Q then forwards to alarm2 which the nas attaches to.

    We also dont use the alarm-enrichment, and switched the Q's so alarm_enrichment can run, and is found on updates but doesnt do anything (just talking to itself). Perhaps a workaround for next time ;->

     

    cheers

    I've also disabled alarm_enrichment as I don't use it and it's an unstable component. Also, I really don't like anything that intercepts messages before they get to NAS.

     

    I recommend you contact support if you decide to disable, as it is not quite so straight forward as "normal" probes. It's important to disabled alarm_enrichment properly, as it changes the alarm and alarm2 queues at startup.

    Sometimes I feel I'm the only person in the world using alarm_enrichment. Not sure if it makes me proud or scared.
