Hi,

I created a remotething in new composer by binding tag from kepservex,and added a anomly alert, then I go to mashup Anomaly_Dashboard to monitoring my newly created thing, but it always failed of training.

Here is error log:

Hello, Tom.

We found some internal documentation which suggest trying the following:

  • Use the fully qualified hostname or ip address of the results micro service server in the results.destination.uri property in microservice.properties, for example
results.destination.uri=results://myserver.mydomain.com:8096/results/models
  • Restart the training and results microservices
  • Then reset the alert using the RetrainAlert service or  DisableAlertsForProperty /  EnableAlertsForPropertyservices of the monitored Thing

Can you try this and let us know the results?

Thanks,

-- Craig A.

Hi Craig,

Thanks for your help, here is my configruation of  microservices.properties

dataset.webservices.url=

dataset.app.id=

dataset.app.key=

results.destination.uri=results://192.168.31.202:8090/results/models

file.storage.path=tempStorage

I can access http://192.168.31.202:8090/results/models​ in browser at Thingworx server. And I already restart Tomcat of Thingworx, and restart the training and results microservices.  Then using RestartAnomalyAlert service to retrain,but I got the same error. I doubt something wrong with my database.


It seems I can't use DisableAlertsForProperty or EnableAlertsForProperty services in  AnomalyServices, because it doesn't accept parameter of thing name. Also I can't use service of RetrainAnomalyAlert, it says:

JavaException: com.thingworx.common.exceptions.InvalidRequestException: Attempted to retrain ThingWatcher [Thing4Anomaly2-Simulation_Examples_Functions_Ramp1-amomalydemo2] that is in an unsupported state [FAILED] (RetrainAnomalyAlert#38)


Thanks & Best Regards

Tom

Hi Tom

Could you provide some more details as below:

- are you deploying the microservices as docker or jar file ?

- could you provide the full command you execute to start the microservices or docker run command

- could you send a screenshot of AlertProcessingSubsytem > Configuration page

- are ThingWorx and microservices on the same machine or different ?

- what is the OS of ThingWorx server and microservices server ?

Could you uplaod:

- ThingWorxStorage/logs/ApplicationLog.log

- Tomcat/logs from ThingWorx machine

Note to reset the alert you can maybe try the disableAllAlert and EnableAllAlert service instead for the time being.

Thanks

Christophe
