There are two ways to access the admin socket:

1. Using the Ceph daemon-name:

        $ sudo ceph daemon {daemon-name} {option} 

2. The default location is /var/run/ceph. Using the absolute path of the socket file:
   

        $ sudo ceph daemon {absolute path to socket file} {option}

We will now try to access the Ceph daemon using the admin socket:

1. List all the available admin socket commands for the OSD:

        # ceph daemon osd.0 help

2. Similarly, list all the available socket commands for MON:

        # ceph daemon mon.ceph-node1 help

3. Check the OSD configuration settings for osd.0:

        # ceph daemon osd.0 config show

4. Check the MON configuration settings for mon.ceph-node1:

        # ceph daemon mon.ceph-node1 config show

5. To get the current config value for osd, use the _recover_max_chunk parameter for the osd.0 daemon:

        # ceph daemon osd.0 config get osd_recovery_max_chunk

6. To change the osd_recovery_max_chunk value for osd.0, execute the following command:

        # ceph daemon osd.0 config set osd_recovery_max_chunk 1000000
