I'm currently studying for my AZ-104 exam, and I've mostly worked with Azure in a pretty focused way. I've just come across the difference between 'Alert Rules' and 'Alert Processing Rules' in Azure Monitor, and I'm trying to wrap my head around it.
Initially, I thought Alert Rules could be very powerful for SRE or DevOps roles because of their potential to utilize runbooks, functions, and webhooks. However, I found that Alert Processing Rules, while also applicable to these roles, seem more oriented towards administrative and notification tasks post-event.
Since both types of rules can trigger action groups, I'm wondering how they can coexist without causing issues—like if an admin suppresses alerts and it leads to a system failure. I'm uncertain how these tools are intended to be used and managed at scale in real-world scenarios. Are people generally using one rule for one purpose and a different tool for others, or is there a way to integrate both effectively?

A practical use case for Alert Processing Rules is to suppress alerts during maintenance periods, like when you’re patching systems. If you know when machines will reboot, you can set these rules up to mute alerts during that time, preventing a flood of notifications. Just be careful with this approach—coordinate closely with those managing the Alert Rules to ensure seamless operations!
Alert Rules define what alerts to create, while Alert Processing Rules determine when and how to handle those alerts. You might want to check out Azure Monitor baseline alerts for more insights! They're designed to help differentiate these roles better.
