dirstat && home-sizes-prom

home-sizes-prom

A textfile collector for node-exporter. It outputs the summarized sizes of subdirectories under a given folder (default: /home) in Prometheus exporter metrics format.

It provides optional cache mechanism based on modification date of files. It can be used by a metric monitor to quickly estimate the used space without scanning the whole disk every time. You can tune the analyzing depth and threshold of durations to make it more accurate.

Usage

Analyze /home

    $ home-sizes-prom

Analyze /data

    $ home-sizes-prom /data

Analyze /home with cache

    $ home-sizes-prom /home -c /var/lib/home-sizes/home.msgpack

Analyze /home with cache, depth limit and reliable estimation duration

    # Set depth=3 and regard those folders modified 1 months ago in cache as reliable sizes
    $ home-sizes-prom /home -c /var/lib/home-sizes/home.msgpack -d 3 -t 30
