Appreciate you have removed cmon and solved the problem; however, in having
a more leisurely look at the cmon source I see there already s the ability
for the user to add mounts to the ignore list via the ignored_mounts config
option. If the ignore list is not specified by the user the default ignore
list (hard coded in cmon.py) is used, ignored_mounts is specified then that
list is used in lieu of the default. Furthermore, when checking a given
mount point against the ignore list, the check used is whether the mount
point in question starts with any of the entries in the ignore list. So
using '/var/lib/docker' in the ignore list *should* work and cause all
docker overlays to be ignored (the source used by cmon as the mount points
universe on a system is the contents of /proc/mounts with the mount points
being the second entry on each line). For info, the entries in the default
ignore list are '/lib/init/rw',
'/proc', '/sys', '/dev', '/afs', '/mit', '/run', '/var/lib/nfs'. So
something like:
[ComputerMonitor]
....
ignored_mounts =
'/lib/init/rw', '/proc', '/sys', '/dev', '/afs', '/mit', '/run',
'/var/lib/nfs',
'/var/lib/docker'
should work. Note, the apostrophes should not be required but leaving them
in won't hurt.
My apologies for the earlier mis-information.
