问题监控 hadoop 响应

Question

我正在使用 ganglia 来监控 Hadoop。 gmond 和 gmetad 运行很好。当我在 gmond 端口 (8649) 上远程登录以及在其 xml 应答端口上远程登录 gmetad 时，我没有获得 hadoop 数据。怎么可能？

cluster {
  name = "my cluster"
  owner = "Master"
  latlong = "unspecified"
  url = "unspecified"
}

host {
  location = localhost
}

udp_send_channel {
  #bind_hostname = yes 
  #mcast_join = 239.2.11.71
  host = localhost
  port = 8649
  ttl = 1
}

udp_recv_channel {
  #mcast_join = 239.2.11.71
  port = 8649
  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
}

tcp_accept_channel {
  port = 8649
  # If you want to gzip XML output
  gzip_output = no
}

我发现问题了。它与 hadoop 指标属性有关。我在 hadoop-metrics.properties 中设置了 ganglia 但我必须设置 hadoop-metrics.properties 配置文件。现在 ganglia 抛出正确的指标。
