mongo_graph: a rrdtool graphing utility for MongoDB

Posted by & filed under Mongodb, Python.

I just uploaded a little utility that pulls performance data from MongoDB and loads it into rrdtool for trending and analysis.

I recently created some utility functions to startup, mount and stop Oracle via cx_Oracle and thought I would share them.
