It would be very nice to be able to read /proc /sys values via the agent, actually any file, by row and field number.

Something like: file.read(/proc/meminfo, 10, 2) to get line 10, field 2 of meminfo.

This way we can get lots of stats the agent can't get, including memory, kernel, disk, etc.

A more advanced version would include the ability to use a macro or key such as hda for things like /sys/block/$drive/queue or even add up using /sys/block/*/queue. Have to think more about how that could be used.

For now we use a custom script to get this, but it would provide a powerful way to extend the agent.
