I have been playing quite a bit with MongoDB lately. MongoDB is a nosql type database. It’s different than a simple k/v store however. It allows sorting, secondary indexes and such. It’s format is BSON a binary representation of JSON with some additions.
Anyway.. Wow what a mind bender working in the ‘schema-less’ nosql type databases is.
One of the things I needed in order to evaluate performance is a tool similar to pgstat2 and/or iostat for mongodb performance. So yet again, I created a tool, and posted it up on github. It’s still just beta and quite simple. Feel free to give feedback on github.
