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.
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.
Sometimes clashing log entries would print on the same line, likely due
to some sort of race condition in Python's print() built-in.
Instead, add a newline to our actual message and print without an end
character. This ensures atomic printing of our log messages.
If the health daemon starts too soon during a node bootup, it will
generate generate tons of erroneous faults while the node starts up.
Adds a conditional wait for the current node daemon to be in "run"
state before the health daemon really starts up.
