Enabling
|
||
|
|
--------
|
||
|
|
|
||
|
|
To check if the *iostat* module is enabled, run::
|
||
|
|
|
||
|
|
ceph mgr module ls
|
||
|
|
|
||
|
|
The module can be enabled with::
|
||
|
|
|
||
|
|
ceph mgr module enable iostat
|
||
|
|
|
||
|
|
To execute the module, run::
|
||
|
|
|
||
|
|
ceph iostat
|
||
|
|
|
||
|
|
To change the frequency at which the statistics are printed, use the ``-p``
|
||
|
|
option::
|
||
|
|
|
||
|
|
ceph iostat -p <period in seconds>
|
||
|
|
|
||
|
|
For example, use the following command to print the statistics every 5 seconds::
|
||
|
|
|
||
|
|
ceph iostat -p 5
|
||
|
|
|
||
