PSUtils extensions to metrics logging
metlog-psutils is a plugin extension for Metlog <http://github.com/mozilla-services/metlog-py>. metlog-psutils provides details about network connections, memory usage, cpu usage and even some thread details.
This plugin works best on Linux. Running the plugin under OSX will skip some functionality and will require root privileges.
