Three common issues and how Monitis can help:
- Too many connections: Open connections consume resources. Too many open connections can take down your entire instance even if they are not running any queries.
- More data than RAM: Keeping an eye on the “virtual memory” is the best way to gauge the performance of your Mongo instances.
- Timeouts: With a custom Monitis Monitor reading the HTTP Console you can find out if your database is throwing timeouts.
Monitis is for those running their own monitoring infrastructure. But if you want a hosted monitoring solution there are a couple of options available too: 10gen’s MongoDB Monitoring Service, Boxed Ice Server Density, and probably more that I’m forgetting right now.
