Hi @Anonymous ,
It seems that there is no out-of-the-box alerting capabilities on Azure Subscription Limits.
Still, since you can get the usage / quota information on any Resource Type you are running in your subscriptions, you can query that data (through PowerShell to generate alerts / send that information to an Azure Log Analytics Workspace) and then generate an Azure Monitor Alert when your defined threshold is breached on one of the Resource Types.
The process of achieving that is presented in the following article:
- Create a PowerShell Azure Automation Runbook that reads details about each resource type quota and usage and writes this data in Log Analytics Workspace
- Azure Monitor executes an Alert Rule by running a query on that Workspace and triggering alerts when quota defined thresholds are breached

I hope it helps!
