集群的一个节点未显示在Ganglia web门户中

在Ganglia中，我配置了2个集群。集群A有2个节点，集群B分别有13个节点。集群B运行良好，而集群A仅显示1个节点。另一个节点具有完全相同的gmond.conf文件，如下所示：

globals {                    
  daemonize = yes              
  setuid = yes             
  user = ganglia              
  debug_level = 0               
  max_udp_msg_len = 1472        
  mute = no             
  deaf = no             
  host_dmax = 0 /*secs */ 
  cleanup_threshold = 300 /*secs */ 
  gexec = no             
  send_metadata_interval = 0     
} 

cluster { 
  #name = "unspecified" 
  name = "rpt" 
  owner = "unspecified" 
  latlong = "unspecified" 
  url = "unspecified" 
} 

host { 
  location = "unspecified" 
} 

udp_send_channel { 
  #mcast_join = 239.2.11.71 
  host = qt-dw-master
  port = 8557 
  ttl = 1 
} 

/*
udp_recv_channel { 
  #mcast_join = 239.2.11.71 
  port = 8557 
  #bind = 239.2.11.71 
  #bind = qt-dw-master
} 
*/

tcp_accept_channel { 
  port = 8557
}

data_source "rpt" 60 rpt0:8557 rpt1-db:8557

qt dw主机上的gmetad.conf如下所示：

globals {                    
  daemonize = yes              
  setuid = yes             
  user = ganglia              
  debug_level = 0               
  max_udp_msg_len = 1472        
  mute = no             
  deaf = no             
  host_dmax = 0 /*secs */ 
  cleanup_threshold = 300 /*secs */ 
  gexec = no             
  send_metadata_interval = 0     
} 

cluster { 
  #name = "unspecified" 
  name = "rpt" 
  owner = "unspecified" 
  latlong = "unspecified" 
  url = "unspecified" 
} 

host { 
  location = "unspecified" 
} 

udp_send_channel { 
  #mcast_join = 239.2.11.71 
  host = qt-dw-master
  port = 8557 
  ttl = 1 
} 

/*
udp_recv_channel { 
  #mcast_join = 239.2.11.71 
  port = 8557 
  #bind = 239.2.11.71 
  #bind = qt-dw-master
} 
*/

tcp_accept_channel { 
  port = 8557
}

data_source "rpt" 60 rpt0:8557 rpt1-db:8557

我尝试过使用多播，但不起作用。我还想找到gmond的日志文件，但失败了。有人可以帮助解决这个问题吗？

集群A中是否都运行gmond？使用commond service gmond status对其进行确认
