The old "(below)" text is not accurate, the service spec definition is
not in the same file at this point in time. This commit adds a ref link
to the actual service specification section.

Add the ability to dump labeled perf counters
for a daemon. Labeled perf counters are stored
in a CephContext's PerfCountersCollection.
Labeled and unlabeled perf counters are dumped
to the admin socket via `counters dump` command.
The schema for labeled and unlabeled perf
counters are dumped to the admin socket via
`counters schema` command.
This commit includes docs and additional unit tests

The string returned by get_system_type() for RHEL 8.4 recently wasn't
one of the strings that xfstests_dev.py expects. The string returned
this time was instead "rhel". Add this string to the list of strings
that xfstests_dev.py expects for Red Hat OS family so that this failure
won't occur again in future. Also log the detected distro and version so
that it is easier to debug when this issue occurs next time.

The previous attempt to fix this issue
(https://github.com/ceph/ceph/pull/50207) was not successful, since the
PIP syntax for compatible versions (~=) behaves differently compared to
other package management tools (e.g.: npm).
In this case, package~=x.y.z equasl to package>=x.y.z;package==x.y.*,
instead of the desired package>=x.y.z;package==x.*.

Otherwise the setting doesn't take effect. While at it, replace

This commit adds unit test coverage to the read balancing
feature, including small vs. large osdmap scenarios,
random osdmap scenarios, and scenarios that involve
tweaking primary affinity on an OSD.
Signed-off-by: Laura Flores <lflores@redhat.com>
This commit adds the capability to balance reads on a
given osdmap with the osdmaptool. The user has the option
of performing a "dry run" of read balancing OR taking it a
step further and applying the results to a live cluster.
Performing a "dry run" would involve simply running an
osdmaptool command and inspecting the results.
The template for the command is:
`osdmaptool <osd map file> --read <file for command output> --read-pool <pool name>`
An example command a user might run is:
`osdmaptool om --read out.txt --read-pool default.rgw.control`
This commit also adds a `--vstart` flag that allows a user to print ceph
commands in the outfile formatted for a vstart cluster. An example command
a user might run is:
`./bin/osdmaptool om --vstart --read out.txt --read-pool default.rgw.control`
The out.txt file would contain ceph commands prefixed with `./bin/`.
The `--vstart` flag may also be applied to an `--upmap` osdmaptool command.
If the user wants to apply read balancing results from their dry run to a
live cluster, they may either manually apply the ceph commands from the out
file, or run `source <outfile>`.
