Mem Input Plugin

The mem plugin collects system memory metrics.

For a more complete explanation of the difference between used and actual_used RAM, see Linux ate my ram.

Configuration:

# Read metrics about memory usage
[[inputs.mem]]
  # no configuration

Metrics:

Available fields are dependent on platform.
