Thingworks Composer warning information

[amittal-3]

Hello,

I am starting to get couple of warnings in Application log of Thingworx composer. And I would like to understand the implications and reasons for those warnings. I have a functionality where about 20 entities (10 Things and 10 ValueStreams) are created when I create a thing with my custom template as base template.

The warnings I am getting are:

1) "----> Security context stack is growing large : current size = [depth: 22]" 

Another warning is:

2) "Thingworx System Metrics_----------------------------------------------------------------------------_AlertProcessingSubsystem#,         maximumQueueSize= 50000.0, queueSize= 0.0, totalAlertsQueued= 0.0, thingWatcherTrainingService= 1.0, thingWatcherResultService= 1.0, enabledAnomalyAlert= 0.0, disabledAnomalyAlert= 0.0, thingsWithEnabledAnomalyAlert= 0.0, thingsWithDisabledAnomalyAlert= 0.0, anomalyAlertsInLastDay= 0.0, _EventProcessingSubsystem#,         corePoolSize= 16.0, maxPoolSize= 500.0, curentPoolSize= 16.0, activeThreads= 0.0, queueSize= 0.0, largestPoolSize= 16.0, submitedTaskCount= 4318.0, completedTaskCount= 4318.0, _FederationSubsystem#,              clientCount= 0.0, publishedCount= 0.0, updateInterval= 100.0, _FileTransferSubsystem#,            corePoolSize= 10.0, maxPoolSize= 10.0, curentPoolSize= 0.0, activeThreads= 0.0, queueSize= 0.0, largestPoolSize= 0.0, submitedTaskCount= 0.0, completedTaskCount= 0.0, _IntegrationSubsystem#,             numberOfConnectors= 0.0, requestCount= 0.0, _LicensingSubsystem#,               twx_composer= 36.0, twx_mashup_builder= 104.0, twx_named_user= 2.0, twx_things= 57.0, twx_utilities= 0.0, twx_utilities_scm_packages= 0.0, twx_utilities_workflows= 0.0, Mar 2018 license usage stats for (CHECK_IN,CHECK_OUT)= 31.0, DaysRemaining= 106.0, _MessageStoreSubsystem#,            corePoolSize= 10.0, maxPoolSize= 100.0, curentPoolSize= 0.0, activeThreads= 0.0, queueSize= 0.0, largestPoolSize= 0.0, submitedTaskCount= 0.0, completedTaskCount= 0.0, _PlatformSubsystem#,                eventQueueSize= 0.0, streamQueueSize-ThingworxPersistenceProvider= 0.0, valueStreamQueueSize-ThingworxPersistenceProvider= 0.0, memoryInUse= 9.25028456E8, totalMemoryAllocated= 1.073741824E9, thingCount= 180.0, _StreamProcessingSubsystem#,        maximumWaitTime= 10000.0, sizeThreshold= 1000.0, maximumBlockSize= 2500.0, scanRate= 5.0, maximumQueueSize= 250000.0, queueSize= 0.0, totalWritesQueued= 0.0, totalWritesPerformed= 0.0, numberOfProcessingThreads= 5.0, _TunnelSubsystem#,                  activeTunnelCount= 0.0, totalTunnelCount= 0.0, _UserManagementSubsystem#,          userCount= 4.0, _ValueStreamProcessingSubsystem#,   maximumWaitTime= 10000.0, sizeThreshold= 1000.0, maximumBlockSize= 2500.0, scanRate= 5.0, maximumQueueSize= 250000.0, queueSize= 0.0, totalWritesQueued= 1708.0, totalWritesPerformed= 1708.0, numberOfProcessingThreads= 5.0, _WSCommunicationsSubsystem#,        activeWebsockets= 1.0, _WSExecutionProcessingSubsystem#,   corePoolSize= 1000.0, maxPoolSize= 10000.0, curentPoolSize= 1000.0, activeThreads= 0.0, queueSize= 0.0, largestPoolSize= 1000.0, submitedTaskCount= 24430.0, completedTaskCount= 24430.0, _ThingworxServer#,                  systemRuntime= 6 hours,  memoryInUse = 0.925 GB,  totalMemoryAllocated= 1.074 GB,  activeUsers= 1, BoundConnectedThings= 2, UnBoundConnectedThings= 0_----------------------------------------------------------------------------_"

Refer Attachment for these warnings.

I also tried to look through one of the post - 

https://community.ptc.com/t5/ThingWorx-Developers/Security-context-stack-is-growing-large/td-p/513157

But I think that the warning in this context was because of non terminating loop, but I don't think same is the case with me.

Thanks and Regards

The first warning is when the application has a high number of embedded or nested service calls.  Basically if there is a service, that calls another service, that does a property update, that has an event subscription, that calls a service.  This would end up with a stack of 5 (service, service, property, event, service).  Typically nothing to worry about unless the depth number continues to grow, which may indicate a loop.

The second is really an informational message, but since the platform default for logging level is "warn" we log that information at that level.  

Thanks,
