Getting Started with MMS by Kristina Chodorow.
From the post:
Telling someone “You should set up monitoring” is kind of like telling someone “You should exercise 20 minutes three times a week.” Yes, you know you should, but your chair is so comfortable and you haven’t keeled over dead yet.
For years*, 10gen has been planning to do monitoring “right,” making it painless to monitor your database. Today, we released the MongoDB Monitoring Service: MMS.
MMS is free hosted monitoring for MongoDB. I’ve been using it to help out paying customers for a while, so I thought I’d do a quick post on useful stuff I’ve discovered (documentation is… uh… a little light, so far).
MongoDB folks will find this post quite useful.
