Unable to deploy Azure Spatial Analysis container.

Ramesh Damma 0

I followed the instructions (thoroughly) mentioned in the Azure Spatial Analysis container installation guide (https://learn.microsoft.com/en-us/azure/ai-services/computer-vision/spatial-analysis-container) and eventually encountered an error - "invalid character 'l' after object key: value pair", when I checked the logs.

The container contains 5 modules --> $edgeAgent; $edgeHub; spatialanalysis; telegraf; diagnostics

"spatialanalysis" module returned "error" status in runtime.

As per the documentation there is a step wherein we need to configure IoT Deployment Manifest. I believe that I might have missed something in the configuration and maybe that's the reason for container deployment failure.

I used the DeploymentManifest.json file from below link and replaced the values for Billing and APIKEY with Computer Vision resource endpoint and key respectively. (https://go.microsoft.com/fwlink/?linkid=2152189)

Can anyone guide me on how to make the deployment work. Is there any step which is not mentioned in detail in the documentation. Or are there other things which needs to be set in the DeploymentManifest.json file. By going through different links I found a mention of Azure Container Registry, do we need to use it? Why do we need "telegraf" module and do we need to leave the required fields empty for it. [fields - "AZURE_TENANT_ID", "AZURE_CLIENT_ID", "AZURE_CLIENT_SECRET", "region", "resource_id"].

I am using a Standard NC4as T4 v3 (4 vCPUs, 28 GiB memory) VM.

Let me know if the logs would help.

@Ramesh Damma I think for Azure VM you need to use the following manifest file. In the documentation the hyperlink might be incorrect and it points to Azure Stack Edge manifest file instead. Try to use the one below:

https://github.com/Azure-Samples/cognitive-services-sample-data-files/blob/master/ComputerVision/spatial-analysis/DeploymentManifest_for_AzureVM.json

Also, you need to fill in all placeholders in the manifest file wherever you see "replace value" in the manifest file.

First of all thank you for the reply.

Could you please guide me how and what values to fill in all the placeholders for "telegraf", "diagnostics" modules. I believe that I first need to create related services under a resource group and probably then I might be able to get those placeholder values.

For example -

"diagnostics" module --> Upon researching I found out that for "diagnostics" module I may create "Log Analytics workspace" and create a "Azure Monitor for VMs" service from this "Log Analytics workspace" and then I can obtain the "LOGANALYTICS_WORKSPACE_ID"; "LOGANALYTICS_SHAREDKEY".

"telegraf" module --> I followed https://www.manageengine.com/ad-recovery-manager/help/account-configuration/finding-client-id-and-secret.html#:~:text=To%20find%20the%20client%20ID,in%20the%20upper%20right%20corner. to obtain the values for "AZURE_TENANT_ID"; "AZURE_CLIENT_ID"; "AZURE_CLIENT_SECRET"; and used the following command to get the "resource_id" - "az storage account show \ --name <storage-account> \ --resource-group <resource-group> \ --query id \ --output tsv"

Are the above 2 approaches correct? If not, then what all services shall I create in order to get the placeholder values for "telegraf" and "diagnostics" modules.

--> I have attached the error logs (telegraf_logs.txt) for "telegraf" module. Although I there are no error logs for "spatialanalysis" module.

--> I have attached the DeploymentManifest.txt file that I am using.

@Ramesh Damma For telegraf, it refers to the SP client and secret along with your tenant details. See this section from troubleshooting documentation.

For diagnostics, I think you can even configure a storage account, as mentioned here. It might be faster and easier to use storage account by just changing the env section to storage account connection string.

@romungi-MSFT Thank you for the response.

I followed the instructions mentioned for the "telegraf" module deployment but still I am getting the same error stating "instrumentation key is required". (telegraf_logs.txt).

Moreover [echo $display] command returns blank. Does this mean we need to install certain drivers since I am connecting with the VM using ssh only.

Also, the Reported Values are empty (against the Desired Values) for the "spatialanalysis" module as can be seen in image - spatialanalysis-container-module.png ; Spatial-Analysis-containers.png

Since I am using a local video, I uploaded it to the Azure Blob Storage account and am using the SAS URL (http). I have attached the updated DeploymentManifest.txt as well. Could you please help me in identifying are there any missing ends/mistakes in the Deployment Manifest. At the moment I am only concerned about Zone Crossing functionality.
