5 min Azure Functions compute with powershell log analytics workspace

https://learn.microsoft.com/en-us/azure/azure-functions/functions-monitor-log-analytics?tabs=python

Use logging like this

So we followed the tutorial and created a log analytics workspace

Then we added that workspace to the function app to store logs for 7 days

The we can do query’s on logs

We can now set up the logging in the app

example, logging.info(“ALERTMSG-COIN”)

Then we can set up an alert and trigger for that word.

Select

Email/SMS message/Push/Voice: Send various notification types to specific recipients.

The above language is Kusto.

After you have configured it, you will get a mail.

Now we test with injecting that logging statement in the code and publish and wait.

        ]
