Is there a limit on the number of action groups a subscription can have? Looking at the pricing page of Azure Monitor, there is a line saying that:
There is a configuration limit of 5000 metric time-series alert rules, 100 activity log alert rules, and 10 action groups per subscription. Contact Azure support to increase the limit.
However, upon testing within our subscription, we found that we could create more than 10 action groups. Also, Azure subscription limits and quota page does not indicate whether there is a subscription level limit on the number of action groups.
