Configuring anomaly detection on thingworx 8.3

[olatz]

Hi,

I've configured an anomaly detection alert but it is getting "failed" status after being on "calibration" status for a long time.

My environment is:

- Thingworx platform 8.3 and H2 on Ubuntu 

- Anaylitics Server 8.3 on Ubuntu in a different virtual machine

Analytics is working ok because I've created some models before.

I am following the link https://www.ptc.com/en/support/article?n=CS265488 but it is a little bit confusing because it is explained on a windows and without having analytics server installed before.

I am getting confused with the ports. In the video expains that it is using 8080,8081,8090, 8091. But in my case results models are on 8900 and training on 9400. 

I can't find the resolution because I couldn't find where the problem it is. I will appreciate any help. Thanks in advance.

Hi @olatz 

Thank you for the details. I understand your confusion.

The thing is, until and including release 8.3, the anomaly detection does not use ThingWorx Analytics Server. Only starting with release 8.4 does anomaly detection uses ThingWorx Analytics Server.

This is why the video you saw in the article https://www.ptc.com/en/support/article?n=CS265488   do not use ThingWorx Analytics Server.

As indicated in the video Deploying Training and Results microservices, you need to download the  ThingWorx-Analytics-ThingWatcher-8-3-0 media from PTC Software Download page, then follow the steps on the video.

The steps are very similar between Linux and Windows.

Hope this helps

Kind regards

Christophe

Thanks for the information cmorfin. After installing and configuring thingwatcher as it explains in the videos, anomaly detection doesn't work on my system. Anomaly alert ends in "failure" status. 

I'm getting the following errors:

- training log: 

"ERROR [2020-01-07 08:30:26,075] com.thingworx.analytics.ccc.job.local.AsynchronousMemoryJobExecutor:    Call to TrainingJob [20200107] failed due to:

Thanks in advance for your help.

Hi @olatz 

Given the error you are getting, I would recommend you check https://www.ptc.com/en/support/article?n=CS270006.

Also https://www.ptc.com/en/support/article?n=CS292986 could lead to similar error, but the first article was definitely more common in 8.3.

Hope this helps

Kind regards

Thanks for the information. After setting the file.storage.path parameter in microservice.properties file it seems that it is working becase, finally, it has passed to monitoring status. 

But an error remains in results log:

"192.168.243.87 - - [08/Jan/2020:07:43:22 +0000] "POST /results/models HTTP/1.1" 201 1024 "-" "Jersey/2.23.2 (HttpUrlC onnection 1.8.0_92)" 595

! javax.ws.rs.NotFoundException: HTTP 404 Not Found
! at org.glassfish.jersey.server.ServerRuntime$2.run(ServerRuntime.java:323)...."

Any idea of what is it? The alert is in Monitoring status but, after this error, I am not convince it it is working properly.

Thanks in advance.

Hi @olatz 

You can ignore this error. As you can see it is reported as INFO only and it is a trace we do get when accessing the /results/models or /training url the first time.

If your alert is in monitoring state, this indicates that it is functioning.

Kind regards
