• gmond.confの編集

  [root@testserver19_0 ~]# vim /etc/ganglia/gmond.conf
  
  # ommit
   
  cluster {
    name = "MyCluster"
    owner = "unspecified"
    latlong = "unspecified"
    url = "unspecified"
  }
  
  # ommit
  
  udp_send_channel {
    #bind_hostname = yes # Highly recommended, soon to be default.
                         # This option tells gmond to use a source address
                         # that resolves to the machine's hostname.  Without
                         # this, the metrics may appear to come from any
                         # interface and the DNS names associated with
                         # those IPs will be used to create the RRDs.
    #mcast_join = 239.2.11.71
    host = 192.168.0.1
    port = 8649
    ttl = 1
  }
  
  # ommit
  
  udp_recv_channel {
    #mcast_join = 239.2.11.71
    port = 8649
    #bind = 239.2.11.71
    #retry_bind = true
    # Size of the UDP buffer. If you are handling lots of metrics you really
    # should bump it up to e.g. 10MB or even higher.
    # buffer = 10485760
