    I am using CA APM 10.5.1. Currently we have a problem with team center that showing no data.

    Experience View No Data

    Map View No Data

    It happened intermittently, and in the IntroscopeEnterpriseManager.log I see some exceptions like this:


    8/18/17 11:55:50.654 AM ICT [WARN] [Central Fast Correlation incubator queue consumer thread] [Manager.AppMap] Exception when processing Central Fast Correlation incubator
    8/18/17 11:55:54.399 AM ICT [WARN] [Central Slow Correlation incubator queue consumer thread] [Manager.AppMap] Exception when processing Central Slow Correlation incubator


    And there are many message saying vertex association not found like this:


    8/20/17 02:48:18.978 AM ICT [WARN] [AppMapAsyncExecutor-7] [Manager.AppMap] Vertex association not found: 12858
    8/20/17 02:48:20.293 AM ICT [WARN] [AppMapAsyncExecutor-8] [Manager.AppMap] Vertex association not found: 14066


    I found the KB about that message: What does the "Vertex association not found" [WARN] message in the IntroscopeEnterpriseManager.log mean?  But we didn't change the data source for team center. I attached the enterprisemanager log file. Any suggestions?

    Hi Yan,


    I noticed some other exceptions in the log, "[Manager.AppMap] Error happened during controller invocation!
    com.wily.introscope.appmap.rest.exceptions.RestApiException: ACCESS_FORBIDDEN", but there is only 1 on August 18 (previous August 1) and that was for  the "guest" user who might have no access.


    As the problem is intermittent the root cause may be related to the MOM/cluster performance.
    Have you noticed high heap usage from the MOM java process? (the perflog.txt might also show symptoms of that)
    Can you enable DEBUG on the MOM to see if the EM log shows more useful information?

    The log starts around mid-May but does not have the last restart timestamp so I cannot see exact 10.5.1.x version/Build. Do you know if this is 10.5.1 GA ( or 1HF1 ( or later HotFix version?
    Ultimately this maybe a scenario that is best handled by a support case where more detailed research can be done.

    Follow up: Yan has raised a support case (00822834) for these symptoms as it is impacting Production Environment 


    On Team Center UI also seeing: Error reading data from polling URL: ../apm/appmap/private/permission: Retrying in 60000 ms. Attempt 1 

    Stopping WebView, clearing its osgi cache (WEBVIEW_HOME\product\webview\configuration EXCEPT config.ini) & restart did not help

    Only after the MOM itself was restarted was the problem resolved (last restart was mid May). At this stage root cause not known & will post here if determined **

    Hi Lynn,


    Let me give the detailed steps to solve this issue.


    1 - Stop the webview follow by EM
    2 - Go to the \product\webview\configuration directory
    3 - Go to the \product\enterprisemanager\configuration directory
    Delete all directories only : ( do NOT delete the config.ini )
    4 - Go to the \work directory and delete its contents.
    5 - Clear the appropriate browser cache.
    6 - Start EM, follow by webview


    And yes, I still need to know what is the root cause of this issue.

    Are you having a similar problem and you want to try the above steps?

    Do you mean how to perform just the stop and start steps?

    What OS platform are your EM and WebView running under?

    The start stop procedure for the EM is documented here


    Start or Stop the Enterprise Manager - CA Application Performance Management - 10.7 - CA Technologies Documentation 


    similarly on Linux there is a WVCtrl.sh script and windows service if that is ho wit was configured during installation.
