Sensu Extension to collect metrics in /proc/net/snmp

Hi sensu-users,

I’ve just released sensu-extensions-proc-net-snmp extension1 on rubygems. This is like the great system_profile2 extension but for collecting metrics in /proc/net/snmp. Installation instructions and example output are available in the README.md3.

I’m not an experienced Ruby programmer. Please file an issue or send a PR if you find any issues.

I hope someone find it useful.
