index analyzer for mongodb
Step 1: In the db you'd like to analyze, from the mongo shell, run db.setProfilingLevel(2);
(be careful if you're doing this in a production system, because it will affect performance)
Step 2: So far this only has a couple of hours put into it--a lot more to come. For now, you can copy the javascript in
indexStats.js into the mongo shell, and then run db.indexStats()
. It will provide you with a list of indexes that aren't being used,
as well as a list of queries that aren't using any indexes (which might not be the end of the world).
