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)

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

Installation

Plop the contents into /opt/memmon

add a crontab entry to run it (I do every minute like so):
