    Are they showing a metric collection error? If so, I just ran into this problem. The issue was that the /home/cellmonitor/.ssh directory didn't have the correct permissions:
    [root@dm03cel01 ~]# ls -al /home/cellmonitor/.ssh
    total 12
    drwx------ 2 root root 4096 Jan 11 12:42 .
    drwx------ 3 cellmonitor cellmonitor 4096 Jan 11 12:42 ..
    -rw-r--r-- 1 root root 3726 Jan 13 09:57 authorized_keys
    This is incorrect. We had to change the ownership and permissions of the /home/cellmonitor/.ssh directory, and the /home/cellmonitor/.ssh/authorized_keys file:
    [root@dm03cel01 ~]# chown -Rf cellmonitor:cellmonitor /home/cellmonitor/.ssh
    [root@dm03cel01 ~]# chmod 700 /home/cellmonitor/.ssh
    [root@dm03cel01 ~]# chmod 600 /home/cellmonitor/.ssh/authorized_keys
    [root@dm03cel01 ~]# ls -al /home/cellmonitor/.ssh
    total 16
    drwx------ 2 cellmonitor cellmonitor 4096 Jan 18 09:12 .
    drwx------ 3 cellmonitor cellmonitor 4096 Jan 18 09:04 ..
    -rw------- 1 cellmonitor cellmonitor 4551 Jan 18 09:03 authorized_keys
    You can test the connectivity by running "ssh cellmonitor@<cell_hostname> cellcli -e list cell" from the database server that is monitoring the cell. If it asks for a password, you still have a connectivity issue.
