此篇仅作为入门。

# vi /etc/gmetad.conf
modify:
data_source "your_cluster_name" 192.168.88.*
# service gmetad restart

# vi /etc/gmond.conf：
modify:
cluster {
  name = "your_cluster_name"
  owner = "user_name"     
  latlong = "unspecified"  
  url = "unspecified"
}
# service gmond restart

 

note:
in RHEL4 or higher version operating systems
disable SElinux ;if it's not effective then
edit /etc/selinux/targeted/contexts/files/file_contexts

and add
/var/lib/ganglia/rrds(/.*)?    

system_u:object_r:httpd_sys_script_exec_t
then run: setfiles file_contexts /var/lib/ganglia/rrds/
that's all.
