修改下面内容
cluster { name = "server" owner = "unspecified" latlong = "unspecified" url = "unspecified" } udp_send_channel { #mcast_join = 239.2.11.71 host = master port = 8649 ttl = 1 } 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 }
修改HTTP访问配置
vi /etc/httpd/conf.d/ganglia.conf
修改下面内容
Alias /ganglia /usr/share/ganglia <Location /ganglia> Order deny,allow Allow from all #Require local # Require ip 10.1.2.3 # Require host example.org </Location>
设置ganglia监控程序链接到指定目录
ln -s /usr/share/ganglia/ /var/www/html/ganglia
修改apache配置
vi /etc/httpd/conf/httpd.conf
将Directory里的内容改为
# 修改80端口为10080，防止后面与nginx端口冲突 Listen 10080 <Directory /> AllowOverride none Order Allow,Deny Allow from all #Require all denied </Directory>
systemctl start httpd.service
systemctl start gmetad
systemctl start gmond
systemctl enable httpd.service
systemctl enable gmetad
systemctl enable gmond
启动服务
rrdcached /usr/bin/rrdcached -p /var/run/ganglia/hdp/rrdcached.pid -m 664 -l unix:/var/run/ganglia/hdp/rrdcached.sock -m 777 -P FLUSH,STATS,HELP -l unix:/var/run/ganglia/hdp/rrdcached.limited.sock -b /var/lib/ganglia/rrds -B -t 4 -w 3600 -f 7200 -z 1800 -F
设置开机启动
vi /etc/rc.local
在尾部添加下面配置
/usr/bin/rrdcached -p /var/run/ganglia/hdp/rrdcached.pid -m 664 -l unix:/var/run/ganglia/hdp/rrdcached.sock -m 777 -P FLUSH,STATS,HELP -l unix:/var/run/ganglia/hdp/rrdcached.limited.sock -b /var/lib/ganglia/rrds -B -t 4 -w 3600 -f 7200 -z 1800 -F
在其他服务器上做下面操作
vi /etc/ganglia/gmond.conf
修改下面内容
cluster { name = "server" owner = "unspecified" latlong = "unspecified" url = "unspecified" } udp_send_channel { #mcast_join = 239.2.11.71 host = master port = 8649 ttl = 1 } udp_recv_channel { #mcast_join = 239.2.11.71 port = 8649 #bind = 239.2.11.71 #retry_bind = true }
vi /usr/local/hadoop/etc/hadoop/hadoop-metrics2.properties
将里面的值全部注释掉，然后替换成下面配置
# for Ganglia 3.1 support *.sink.ganglia.class=org.apache.hadoop.metrics2.sink.ganglia.GangliaSink31 *.sink.ganglia.period=10 # default for supportsparse is false *.sink.ganglia.supportsparse=true *.sink.ganglia.slope=jvm.metrics.gcCount=zero,jvm.metrics.memHeapUsedM=both *.sink.ganglia.dmax=jvm.metrics.threadsBlocked=70,jvm.metrics.memHeapUsedM=40 namenode.sink.ganglia.servers=master:8649 # host请参考gmond.conf中的定义 datanode.sink.ganglia.servers=master:8649 resourcemanager.sink.ganglia.servers=master:8649 nodemanager.sink.ganglia.servers=master:8649 mrappmaster.sink.ganglia.servers=master:8649 jobhistoryserver.sink.ganglia.servers=master:8649 # 注意下面参数，如果修改可能会造成数据量过大，ganglia的磁盘空间迅速占满。 # Switch off container metrics *.source.filter.class=org.apache.hadoop.metrics2.filter.GlobFilter nodemanager.*.source.filter.exclude=*ContainerResource*
vi /usr/local/hbase/conf/hadoop-metrics2-hbase.properties
将里面的值全部注释掉，然后替换成下面配置
*.sink.file*.class=org.apache.hadoop.metrics2.sink.FileSink # default sampling period *.period=10 *.source.filter.class=org.apache.hadoop.metrics2.filter.GlobFilter *.record.filter.class=${*.source.filter.class} *.metric.filter.class=${*.source.filter.class} hbase.sink.ganglia.record.filter.exclude=*Regions* hbase.sink.ganglia.class=org.apache.hadoop.metrics2.sink.ganglia.GangliaSink31 hbase.sink.ganglia.tagsForPrefix.jvm=ProcessName *.sink.ganglia.period=20 hbase.sink.ganglia.servers=master:8649 # host请参考gmond.conf中的定义
systemctl start gmond
systemctl enable gmond
在master服务器上重启hadoop与hbase服务 访问http://192.168.10.90:10080/ganglia/ 查看监控页面
在master服务器输入命令查看监控服务运行状态
gstat –a
systemctl status gmetad –l
当遇到无法查看到监控信息时，可用上面的命令查看运行状态，如果gmetad与gmond服务都正常运行，却在网页端没有图形数据，可以在master服务器输入systemctl restart gmetad重启监控服务，在三个服务器都输入systemctl restart gmond重启监控收集服务。
