  • 1.  EM collector log filling up with postgres error

    Posted May 31, 2016 06:59 AM

    Hi - running APM 9.5.2 - Introscope only.

     

    Our EM logs are filling up with this error - I can't see anything in KB or online for this. Any ideas what we need to do to fix ?

    Hi Dave,

     

    As discussed, the problem is as a result of each collector in the cluster trying to run the CEM processes and create the partitions. This is because the installations were cloned rather than individually installed. If you clone the installation you need to delete the file EMHOME/config/internalserver/tess.internal.properties before starting teh collector (or cloning) as this contains the unique identifier which the APM database holds against the system responsible fro running the various service. On startup the file will be regenerated if not present and so that way each collector will be truly unique and the processing will only be run on one collector in the cluster and so this clash should not take place.

     

    cheers

    Mike

    Hi Dave:

    It looks like Mike has answered your question. May we mark this thread as closed? Or are there followup questions?

     

    Thanks
