Hadoop、HBase配置Ganglia指南（metrics1）-CFANZ编程社区

Server端：

yum install rrdtool ganglia ganglia-gmetad ganglia-gmond ganglia-web httpd php

Client端：

yum install ganglia-gmond

创建RRD目录

mkdir -p /var/lib/ganglia/rrds
chown ganglia:ganglia /var/lib/ganglia/rrds

编辑/etc/ganglia/gmond.conf

cluster {
 
 
 
DFS"
 
 
 

    owner = "unspecified"
 
 
 

    latlong = "unspecified"
 
 
 

    url = "unspecified"
 
 
 

  }
 
 
 

  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 = master.hadoop.test
 
 
 

    port = 8649
 
 
 

    ttl = 1
 
 
 

  }
 
 
 

   
 
 
 

  /* You can specify as many udp_recv_channels as you like as well. */
 
 
 

  udp_recv_channel {
 
 
 

    port = 8649
 
 
 

    bind = master.hadoop.test
 
 
 

  }
 
 
 

   
 
 
 

  /* 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 {
 
 
 

    bind = master.hadoop.test
 
 
 

    port = 8649
 
 
 

  }

编辑/etc/ganglia/gmetad.conf

DFS" master.hadoop.test:8649

安装ganglia-web

cd /var/www/html

wget http://softlayer-dal.dl.sourceforge.net/project/ganglia/ganglia-web/3.5.10/ganglia-web-3.5.10.tar.gz

tar zxvf ganglia-web-3.5.7.tar.gz

mv ganglia-web-3.5.7 ganglia

修改Apache配置

vim /etc/httpd/conf.d/ganglia.conf

Order deny,allow

Allow from all

</Location>

# 开机运行采集进程
chkconfig --levels 235 gmond on
# 开机运行数据存储进程
chkconfig --levels 235 gmetad on
# 开机运行apache服务
chkconfig --levels 235 httpd on

启动服务

service gmond start
service gmetad start
service httpd restart

修改hadoop配置：

vim $HADOOP_HOME/conf/hadoop-metrics.properties

# Configuration of the "dfs" context for ganglia

dfs.class=org.apache.hadoop.metrics.ganglia.GangliaContext31

dfs.period=10

dfs.servers=master.hadoop.test:8649

# Configuration of the "mapred" context for ganglia

mapred.class=org.apache.hadoop.metrics.ganglia.GangliaContext31

mapred.period=10

mapred.servers=master.hadoop.test:8649

# Configuration of the "jvm" context for ganglia

jvm.class=org.apache.hadoop.metrics.ganglia.GangliaContext31

jvm.period=10

jvm.servers=master.hadoop.test:8649

rpc.class=org.apache.hadoop.metrics.ganglia.GangliaContext31

rpc.period=10

rpc.servers=master.hadoop.test:8649

重启Hadoop

修改HBase配置：

hbase.class=org.apache.hadoop.metrics.ganglia.GangliaContext31
hbase.period=10
hbase.servers=master.hadoop.test:8649

jvm.class=org.apache.hadoop.metrics.ganglia.GangliaContext31
jvm.period=10
jvm.servers=master.hadoop.test:8649

rpc.class=org.apache.hadoop.metrics.ganglia.GangliaContext31
rpc.period=10
rpc.servers=master.hadoop.test:8649

rest.class=org.apache.hadoop.metrics.ganglia.GangliaContext31
rest.period=10
rest.servers=master.hadoop.test:8649

重启Hbase
