Adds additional polled information on node cpu, memory, and network
bandwidth for the node running the test. This should provide additional
useful information about the results of the test.
Also bumps the test format to 2 to ensure clients can handle the changes
properly.
Allows an imported volume to be scanned for stats independently.
Designed to be used as part of a snapshot import via API, to allow the
"create" to happen before the real import (to check for available space,
etc.) and then run this import after when the RBD volume actually
exists.
Moves VM autobackups from being in-CLI to being handled by the
pvcworkerd system on the primary coordinator. Turns the CLI autobackup
command into an actual API client endpoint rather than having its logic
in the CLI.
In addition, modifies the new autobackup to leverage the new "pvc vm
snapshot" function set, just with special snapshot names. This helps
automate this within the new snapshot scaffolding.
We supported creating snapshots, but not doing anything with them. This
removes the manual task of restoring a snapshot and replace it with a
PVC abstraction of rolling back to a snapshot.
While Ceph recommends cloning a snapshot instead of rolling back, due to
the time taken, in our usecase I don't think that is an optimal
strategy, as it will leave dangling clones that we'd then have to
manage.
Closes#183
Adds a check that a volume creation or resize won't violate the 80% full
rule for the storage cluster. This ensures a cluster won't get too full
if a storage volume fills up.
Also adds a force flag throughout the pipeline to override this check,
should an administrator really want to do so.
Closes#177
Adds a new flag to VM metadata to allow setting the VM live migration
max downtime. This will enable very busy VMs that hang live migration to
have this value changed.
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.
