Python module for ganglia 3.1.

This module allows you to collect memory metrics that have been left out of stock Ganglia gmond. For example I have it memory dirty and memory writeback. These are values that are collected from

/proc/meminfo

Copy mem_stats.py from python_modules to your python modules directory e.g.

/usr/lib64/ganglia/python_modules

and mem_stats.pyconf to

/etc/ganglia/conf.d/

Restart Gmond and you should be set. If you would like additional memory stats collected look through mem_stats.py for the metric you want then add it to mem_stats.pyconf e.g. if you wanted to keep track of unevictable memory you would add

metric { name = "mem_unevictable" title = "Unevictable memory" value_threshold = 1.0 }

Restart Gmond and you are done.
