How this was being done didn't work, as the backup volume was already
unmounted when we tried to read the backups from it. Instead, populate
the backup summary earlier in the run, during the actual backup.
1. Use the actual response code from the server on error, or 504 on
timeouts instead of 500.
2. Retry GET requests 3 times and only error if the last fails
Shows each subarg of the task_args as its own element, if applicable,
and fits the width to the terminal using MAX_CONTENT_WIDTH instead of an
arbitrary value.
Found an instance where two of these fired too close together, and
caused a fatal error. Use a write lock, and then catch the schema.apply
function in case it fails anyways.
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.
Major improvements to autobackup and backups, including additional
information/fields in the backup JSON itself, improved error handling,
and the ability to email reports of autobackups using a local sendmail
utility.
Adds additional information about failures, runtime, file sizes, etc. to
the JSON output of a VM backup.
This helps enable additional reporting and summary information for
autobackup runs.
Allows an administrator to easily generate a Prometheus file service
discovery configuration via the CLI for all clusters they have
configured. Assumes that all the various connection details are correct,
and due to the limits of the file SD config does not include the scheme
or SSL verification options (as these are global in Prometheus).
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.
