Applicationinsights-js: How to set cloud_rolename to monitor multi role apps.

Created on 27 Oct 2017 · 6Comments · Source: microsoft/ApplicationInsights-JS

I have the same angular frontend deployed several times with different AppServices. I want to be able to distinguish them as each connects to a single AppService using the approach mentioned here: https://docs.microsoft.com/en-us/azure/application-insights/app-insights-monitor-multi-role-apps.

So I assume I need to set the cloud_rolename clientside as well but I can't seem to find any reference on how to do this. My AppServices already show up using the cloud rolename.

To set a customer cloud_rolename you need to write a telemetryInitializer function and set an ai.device.roleName tag on each envelope.

For a full list of tags check ContextTagKeys.ts.

Thank you.

I've edited my code as such:

AppInsights.queue.push(() => {
    AppInsights.context.addTelemetryInitializer((envelope: Microsoft.ApplicationInsights.IEnvelope) => {
                    envelope.tags['ai.device.roleName'] = "MyClientApp";
                });
});

When analysing the page views I can now select the filter 'Cloud role name' which matches 'MyClientApp'.

And I know this is probably not the place for it :) but the application does not show up in the Application Map overview.

I'm glad to hear that it's working. Sorry, I can't help with the App Map, could you ask this question in the MSDN forum - https://social.msdn.microsoft.com/Forums/en-US/home?forum=ApplicationInsights,

Btw, thanks for sharing your code, I added the question to our FAQ section.

This seems no longer valid! :(
