Munin Mongodb Plugin Not Showing. . . ?

Question

I have installed munin and munin-node on my monitoring server and installed munin-node on my mongodb server, I have set them both up and all is working great. But, the mongodb plugins aren't showing on my monitoring server. I see the node listed and "Disk, Network, Processes, System", but not the mongo stuff. If I execute one of the plugins directly on the mongo server "python /usr/share/munin/plugins/mongo_btree" it returns output, but nothing shows on the monitoring server.

Answer 1

Upon further inspection, the "munin" user was receiveing errors when trying to access the simplejson module. This was cause due to the munin user using an older pre 2.6 instance of python.

Fixed by adding the correct version to munin's bash_profile.
