A post by Pandora FMS team about monitoring options for MongoDB:
If MongoDB goes wrong, all your apps will fail. So monitoring the
main variables and configuration parameters of your database is the
best option to make sure that your values are right and your users
The post talks about the tools that come with MongoDB (
mongostat, the stats available through the MongoDB shell, logfiles, etc.), but also introduces their PandoraFMS library. There’s no word about 10gen’s hosted MongoDB Monitoring Service, nor other MongoDB utilities for monitoring or the latest MongoMem collection memory usage library.
In terms of what are the most interesting stats, Simon Maynard’s 5 things to Monitor in MongoDB and these other 3 metrics should be a good start.
