Public bug reported: I've noticed today that collectd tracks disk usage of every version of every snap, since those are squashfs mounts. There are rather a lot of those:
$ ls -ld /var/lib/collectd/rrd/$(hostname -f)/df-snap*|wc -l 262 I suggest adding FSType squashfs to the <Plugin df> block in the default /etc/collectd/collectd.conf.
