Gap in graphs following CAPC upgrade from 2.7 to 2.8

  • 1.  Gap in graphs following CAPC upgrade from 2.7 to 2.8

    Posted 10-11-2016 03:21 AM

    We have just upgraded our CAPC instance from v2.7 to v2.8. This was our very first upgrade since we have CAPC.

    We are very surprised (and unhappy) to see now a gap in the graphs, that is 20 minutes long.

    What is causing that gap and how can we prevent it to occur in the future upgrade.

    To be clear: we had no gap before the upgrade, and there are no more gaps after the upgrade. But it seems that Data Collector stopped collecting data during 20 minutes at the time of the upgrade. Why so long ? Why does it stop at all ?

    Thanks,

    Veronique

    Hello Veronique,

     

    During the upgrade the data collector stops both activemq and the dc ( java process) and this means we dont collect any data from the devices during this time and thats most likely the reason why you are not seing any data during the upgrade time.

    If you look at the install log it will show you all the upgrade tasks being carried out. 

    /opt/IMDataCollector/Logs

    CA_Performance_Management_Data_Collector_Install_

    It definetely depends on the resources available.

    Yes, the upgrade took less than one minute. Why does the data collection stop for more than 1 minute then ?

    Thanks again,

    Veronique

    You can also check the DC install log and see when the installation started and when it ended.

     

    Example 

    Installed Feature(s) Application, Help of CA Performance Management Data Collector

    Install Begin: OCTOBER 7, 2016 10:41:58 AM EDT
    Install End: OCTOBER 7, 2016 10:44:38 AM EDT

     

    You can attach the Latest install log for all the components during the upgrade

    Install Begin: OCTOBER 11, 2016 8:29:19 AM CEST

    Install End: OCTOBER 11, 2016 8:30:07 AM CEST

     

    So, why do we have a 20 minute gap in the data ?

    Thanks,
