  • 1.  AMP issue

    Posted Jan 31, 2013 02:19 PM

    My Airwave platform showed all APs down. This was not in fact true. I rebooted the server, now I cannot connect with a browser.

    Any help appreciated. Thanks.

    What version of AMP was your server running?  This may be the symptom of a larger issue.

     

    Check the server health:

    -disk space (is the / volume full?)

         # df -h

    -memory (is the server hitting swap?)

         # top -c

    -amp disabled? (if this file exists, it means AMP disabled itself)

         # ls /etc/amp_disabled

     

    Other files worth checking:

    /var/log/low_level_service_watcher

    /var/log/service_watcher

    /var/log/httpd/error_log

     

    If nothing obvious stands out, then please open a support case.  Support techs should be able to start a web meeting to diagnose the issue quickly.

    Thanks for the commands, very useful.

     

    The server came up yesterday afternoon.

    I can browse into my AMP application but the only device it sees up is the Standby Controller(VRRP Master/Standby).

    All my APs and the Master are down in AMP, but up and running in reality......bizarre...

    Does System -> Status show all daemons are up in 'green' state?  Or are any items in the 'red'?

     

    Also, what's System -> Performance showing?  Usage of swap?  High database I/O?

    I upgraded to 7.6.2.

    Now I can't get into the server from the browser....

    I ran cat low_level_service_watcher

    This isn't something we've been seeing in our lab during testing.  I've got time to take a look if you're available.  Sending you my contact info in a private message.  You'll be able to access the message by clicking on the envelope next to your name at the top of the Airheads page.

    Thanks for your help Rob!

     

     

     

    AMP restore of 7.5.5 on 7.6.2 code needed to run through database upgrade
    a.       This was accomplished by running # root; make
    b.      We saw the AMP come back online viewing # wd (alias for # watch daemons)
     
    SNMP string had been reconfigured without my knowledge.
