There was a problem hiding this comment.
LGTM, but needs another approval from someone from the insights team I think.

Summary
The filesystem collector's exclude filters have gaps that let container runtime
mounts through. This inflates series count on and added noise to the Droplet Insights Disk Usage chart.
overlayfsdoesn't show up in mount tables, butoverlaydoes, and was seen in Insights disk usage charts. Changing this tooverlaywill also matchoverlayfs.containerdadded alongside docker inignoredMountPointsas precaution to catch any containerd mounts whose type isn'toverlay.Verified that the Droplet Insights disk chart groups no longer shows extraneous mounts by deploying a prerelease image on a live Kubernetes node and confirmed the excess mounts are gone from Insights chart on the Droplet.
