memmon

memmon

An sqlite database populated by cron, ps and awk

Made easy with writable views

Designed to be loaded into grafana (see the .json files herein) and filtered easily by process name via dashboard variables

Uses a recursive CTE to get around unhelpful var interpolation in the sqlite data source (see here)

Installation

Plop the contents into /opt/memmon, chown -R grafana:grafana /opt/memmon

add to root's crontab to run it (I do every minute like so):

* * * * * /opt/memmon/gather_rss.sh

From there, install the provided dashboard.json in this directory and observe charts.
