如何正确配置Unicast中的Ganglia？

Question

我在和Ganglia一起工作，顺便说一句，这是个很棒的工具！我正在尝试使这个拓扑学，一些节点运行centOS 6.4，centOS 5.9。

为此，我尝试为GMetad进行此配置(其余为默认配置)：

##########################################################################
Head Monitor Cluster (GMetad + Gmond > mute no > deaf no + GWeb ) | centOS 6.4 (desktop)
##########################################################################
data_source "head monitor clusters" 10 192.168.1.100 # 192.168.1.100 == localhost
data_source "monitor cluster" 10 192.168.1.51:8649
gridname "Company"
authority "http://192.168.1.100/ganglia/"



##########################################################################
Monitor Cluster (GMond > mute no > deaf no ) | centOS 6.4 (minimal)
##########################################################################

globals {
  daemonize = yes
  setuid = yes
  user = ganglia
  debug_level = 0
  max_udp_msg_len = 1472
  mute = no
  deaf = no
  allow_extra_data = yes
  host_dmax = 86400 /*secs */
  cleanup_threshold = 300 /*secs */
  gexec = no
  send_metadata_interval = 5 /*secs */
}

cluster {
  name = "Monitor"
  owner = "unspecified"
  latlong = "unspecified"
  url = "unspecified"
}

/* The host section describes attributes of the host, like the location */
host {
  location = "unspecified"
}

udp_send_channel {
  host = 192.168.1.51 # send the data collect to itself
  port = 8649
  ttl = 1
}

udp_send_channel {
  host = 192.168.1.100 #send the data to 
  port = 8649
  ttl = 1
}


/* You can specify as many udp_recv_channels as you like as well. */
udp_recv_channel {
  port = 8649
}

/* You can specify as many tcp_accept_channels as you like to share
   an xml description of the state of the cluster */
tcp_accept_channel {
  port = 8649
}


##########################################################################
Node (Gmond > mute no > deaf yes ) | centOS 5.9 (minimal)
##########################################################################

/* This configuration is as close to 2.5.x default behavior as possible
   The values closely match ./gmond/metric.h definitions in 2.5.x */
globals {
  daemonize = yes
  setuid = yes
  user = ganglia
  debug_level = 0
  max_udp_msg_len = 1472
  mute = no
  deaf = yes
  host_dmax = 86400 /*secs */
  cleanup_threshold = 300 /*secs */
  gexec = no
}

cluster {
  name = "Monitor"
  owner = "unspecified"
  latlong = "unspecified"
  url = "unspecified"
}

/* The host section describes attributes of the host, like the location */
host {
  location = "unspecified"
}

/* Feel free to specify as many udp_send_channels as you like.  Gmond
   used to only support having a single channel */
udp_send_channel {
  host=192.168.1.51 #send to monitor cluster
  port = 8649
  ttl = 1
}

/* You can specify as many udp_recv_channels as you like as well. */
udp_recv_channel {
#  mcast_join = 239.2.11.71
  port = 8649
#  bind = 239.2.11.71
}

/* You can specify as many tcp_accept_channels as you like to share
   an xml description of the state of the cluster */
tcp_accept_channel {
  port = 8649
}

就是这样。但是这个配置不起作用，我已经设置了9台虚拟机来完成这个任务，但是到目前为止还没有。I disabled iptables, ip6tables and selinux。我日日夜夜都在做这件事，似乎什么都没有.我想在这方面得到一些帮助，求你了，我求你了。在阅读了那么多关于Ganglia的教程和O‘really的书之后，我真的不明白为什么这个配置不起作用。知道吗？还是帮忙？

是的，如果我知道的话:从192.168.1.1008649 telnet 192.168.100 8649，所收集的全部数据将显示出来。。

同样的事情发生在192.168.1.51上，来自192.168.1.100，但是这个不显示在Ganglia中。它的图表总是-nan.。

知道吗？谢谢!

Answer 1

我解决了这个问题。由于某种原因，ganglia-gmond 5.*是EPEL包附带的gmond-3.0.7，但是我添加了rpmforge存储库，可以找到支持单播配置的3.1.7版本，现在一切正常。

谢谢!
