Since these are unauthenticated, it might be the case that an
administrator wishes to completely disable these metrics endpoints.
Provide that option via pvc.conf through pvc-ansible's existing
enable_prometheus_exporters option and the new enable_prometheus
configuration flag.
Defaults to "yes" to provide all functionality unless explicitly
disabled, as the author assumes that the PVC API is secured in other
ways as well and that metric information is not completely sensitive.
Adds a new physical network interface stats parser to the node
keepalives, and leverages this information to provide a network
utilization overview in the Prometheus metrics.
Moves all tasks run by the Celery worker into a discrete package/module
for easier installation. Also adjusts several parameters throughout to
accomplish this.
For whatever reason, a Celery worker on <5.2.x was not picking these up.
Move them back to the root of the module so they are properly picked up
on these older versions but still prevents calling the routing functions
during an API doc generation.
Avoids calling unworkable functions when generating API docs etc. by
isolating them into a Celery startup function called by Daemon.py.
Also update to Celery 4+ settings format.
Updates all the example provisioner scripts to use the new functions
exposed by the VMBuilder class as an illustration of how best to use
them.
Also adds a wrapper fail() handler to ensure the cleanup of the script,
as well as the global cleanup, are run on an exception.
Full UUIDs were obnoxiously long, so switch to using just the first
8-character section of a UUID instead. Keeps the list nice and short,
makes them easier to copy, and is just generally nicer.
Could this cause uniqueness problems? Perhaps, but I don't see that
happening nearly frequently enough to matter.
