We've deployed Azure Functions on Linux to an Azure Container Instance.
Unfortunately, the application insights logging is not displaying my cloud_RoleName at all using the default ILogger. In order to query logs by container, I need to set the cloud_RoleName to the name of the container image.
How can I set this telemetry property without having to use the Telemetry Client directly?
As stated in kudu we managed to set the cloud_RoleName property by adding this environment variable to our ARM template in the Microsoft.ContainerInstance/containerGroups section in the ContainerProperties EnvironmentVariable array:
{
"name": "WEBSITE_SITE_NAME",
"value": "[parameters('containerGroups_name')]"
}
Now the logs in AppInsights contain the value set in the WEBSITE_SITE_NAME variable and we can easily query our logs as follows:
traces | where cloud_RoleName == "containerName"
This might also work for the cloud_RoleInstance by setting the WEBSITE_INSTANCE_ID environment variable.
