Thanks Jose! Your response was very insightful.
We did encounter one hiccup: being able to have separate counts across different topics. The issue is when you receive a :DOWN event from a monitored pid, you don’t know which count to decrement. To solve this, we’ve decided to keep a basic key/value pair of pid to topic record in an ets table. Once you receive a :DOWN event, we’ll check which topic that pid belongs to, and then remove it from the ets table.
I’ll report back with some more code, or perhaps a gist of code for the benefit of future readers.
