MongoMem: Memory Usage by Collection in MongoDB

MongoMem, a Python tool, by Wish Tech team:

Today, we’re releasing the first of these tools, MongoMem. MongoMem solves the age-old problem of figuring out how much memory each collection is using. In MongoDB, keeping your working set in memory is pretty important for most apps. The problem is, there’s not really a way to get visibility into the working set or what’s in memory beyond looking at resident set size or page faults rate.
