How to know the status of the monitors?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi, all:

    Is there any command or API can retrieve the status of all monitors?

    I use ‘ceph mon stat’ to get this information. However, the mon.e is not available (server is shutdown).

      2011-12-13 17:08:35.499022 mon <- [mon,stat]
   2011-12-13 17:08:35.499716 mon.1 -> 'e3: 5 mons at {a=172.16.33.5:6789/0,b=172.16.33.6:6789/0,c=172.16.33.7:6789/0,d=172.16.33.71:6789/0,e=172.16.33.72:6789/0}, election epoch 16, quorum 0,1,2,3' (0)
    
    Even I use ‘ceph mon dump’, I still cannot know if the monitor is alive or not.

		0: 172.16.33.5:6789/0 mon.a
		1: 172.16.33.6:6789/0 mon.b
		2: 172.16.33.7:6789/0 mon.c
		3: 172.16.33.71:6789/0 mon.d
		4: 172.16.33.72:6789/0 mon.e

    Please give some help. Thanks!
