Manage configuration key. It uses some additional subcommands.
-Subcommand ``del`` deletes configuration key.
+Subcommand ``rm`` deletes configuration key.
Usage::
- ceph config-key del <key>
+ ceph config-key rm <key>
Subcommand ``exists`` checks for configuration keys existence.
ceph config-key get <key>
-Subcommand ``list`` lists configuration keys.
+Subcommand ``ls`` lists configuration keys.
Usage::
Usage::
- ceph heap dump|start_profiler|stop_profiler|release|stats
+ ceph heap dump|start_profiler|stop_profiler|stats
+
+Subcommand ``release`` to make TCMalloc to releases no-longer-used memory back to the kernel at once.
+
+Usage::
+
+ ceph heap release
+
+Subcommand ``(get|set)_release_rate`` get or set the TCMalloc memory release rate. TCMalloc releases
+no-longer-used memory back to the kernel gradually. the rate controls how quickly this happens.
+Increase this setting to make TCMalloc to return unused memory more frequently. 0 means never return
+memory to system, 1 means wait for 1000 pages after releasing a page to system. It is ``1.0`` by default..
+Usage::
+
+ ceph heap get_release_rate|set_release_rate {<val>}

ceph osd pool stats {<name>}
+Subcommand ``application`` is used for adding an annotation to the given
+pool. By default, the possible applications are object, block, and file
+storage (corresponding app-names are "rgw", "rbd", and "cephfs"). However,
+there might be other applications as well. Based on the application, there
+may or may not be some processing conducted.
+
+Subcommand ``disable`` disables the given application on the given pool.
+
+Usage::
+
+ ceph osd pool application disable <pool-name> <app> {--yes-i-really-mean-it}
+
+Subcommand ``enable`` adds an annotation to the given pool for the mentioned
+application.
+
+Usage::
+
+ ceph osd pool application enable <pool-name> <app> {--yes-i-really-mean-it}
+
+Subcommand ``get`` displays the value for the given key that is assosciated
+with the given application of the given pool. Not passing the optional
+arguments would display all key-value pairs for all applications for all
+pools.
+
+Usage::
+
+ ceph osd pool application get {<pool-name>} {<app>} {<key>}
+
+Subcommand ``rm`` removes the key-value pair for the given key in the given
+application of the given pool.
+
+Usage::
+
+ ceph osd pool application rm <pool-name> <app> <key>
+
+Subcommand ``set`` assosciates or updates, if it already exists, a key-value
+pair with the given application for the given pool.
+
+Usage::
+
+ ceph osd pool application set <pool-name> <app> <key> <value>
