getting error while running BuildAndRunSimulation

[barnstee]

Looks like you ran BuildAndRunSimulation twice, instead of calling StopSimulation in between?

Hi @barnstee

I have ran only once, if I delete all the containers and Run the file will it resolve? or any other solution to resolve this?

[barnstee]

Stop simulation will clean up everything, so yes. Then simply run BuildAndRunSimulation afterwards.

Hi @barnstee ,

I found the issue there were two network with same name each, i deleted all the networks and rebuilt it,

now except these containers all other are working, these containers are keep on restarting

[barnstee]

Check the logs of ua-cloudcommander and also verify that you have replaced all the occurrences of ENTER_IOT_HUB_HOSTNAME_HERE, ENTER_UACOMMANDER_DEVICE_NAME_HERE and ENTER_UACOMMANDER_DEVICE_KEY_HERE in the BuildAndRunSimulation.cmd file.

Hi @barnstee

Thanks for the support, I made mistake instead of primary key I used primary connection string, now everything is running but unable to monitor the telemetry using Azure IoT Explorer

this is the error I'm getting port 8081 is in use

I can see one of the containers already using this

I have tried using the VS code monitor the built-in endpoint but no data is getting displayed , but from Azure metric I can see messages are getting populated

There are my queries regarding this

1. How to view the telemetry data?
2. How get the view of the digital twin model and twin graph, do need to setup it manually?
3. Is it mandatory to store the data in ADX to get the complete view?

You can simply change the port of the publisher in question in the following file:
https://github.com/digitaltwinconsortium/ManufacturingDTDLOntologies/blob/aa1d5e9f7f880b02cf68d1cf6d6f10c032040727/FactorySimulation/BuildAndRunSimulation.cmd#L92

Regarding visualization, I recommend ADX dashboards. ADX can be configured using this writeup:

Just ignore the bits in relation to configuring the publisher as you have already done that.

There are also sample ADX visualization queries here:

Thanks @barnstee

Coming to digital twin, we need to setup those twin models and model graph, I can see two DTDL files in the folder, do you have any documentation how to setup ?

[barnstee]

Use Azure Digital Twin Explorer to upload them. You can also upload the entire graph in one go.

closing since issue was resolved.
