-# cpu.sh - measures CPU usage at a configurable sample interval
-#
-# Usage: cpu.sh INTERVAL_IN_SECONDS
-#
-# This script will emit the following tags on stdout (N is the number
-# of logical CPUs):
-#
-#  Name   Type
-#  --------------------
-#  cpu    range 0-100
-#  cpu0   range 0-100
-#  cpu1   range 0-100
-#  ...
-#  cpuN-1 range 0-100
-#
-# I.e. ‘cpu’ is the average (or aggregated) CPU usage, while cpuX is a
-# specific CPU’s usage.
-#
-# Example configuration (update every second):
-#
-#  - script:
-#      path: /path/to/cpu.sh
-#      args: [1]
-#      content: {string: {text: "{cpu}%"}}
