Ultra-light docker monitor
=========================

This light tool permits:
 - to export docker container memory usage in a JSON file `stats.json`
 - display curves of the memory usages using the JSON file

The export and the display are two different parts. This allow to run the display in another machine.



Setup the stats export
----------------------

To add it to the cron tab:

	crontab -e

The add new line (to run the check once per hour)

	*/10 * * * * /path.io/docker-stats-histo/save_docker_stats.sh >>/dev/null  2>&1


**Note:**
 - Normaly cron send task outputs (echo) via mail. As the MTA (Mail Transfert Agent), may not be set up,
the crontab line redirect the outputs into `/dev/null`. Can also be a path to a log file.
 - No sudo is needed, crontab is called with current user.


Display stats
