问题导读：
1、如何安装Ganglia监控Hadoop及Hbase集群？

2、它的效能如何？





1. 在主节点上安装ganglia-webfrontend和ganglia-monitor
  1. sudo apt-get install ganglia-webfrontend ganglia-monitor
复制代码
在主节点上安装ganglia-webfrontend和ganglia-monitor。在其他监视节点上，只需要安装ganglia-monitor即可
将ganglia的文件链接到apache的默认目录下
  1. sudo ln -s /usr/share/ganglia-webfrontend /var/www/ganglia
复制代码

2. 安装ganglia-monitor
在其他监视节点上，只需要安装ganglia-monitor
  1. sudo apt-get install ganglia-monitor
复制代码

3. Ganglia配置
gmond.conf
在每个节点上都需要配置/etc/ganglia/gmond.conf,配置相同如下所示
  1. sudo vim /etc/ganglia/gmond.conf
复制代码

修改后的/etc/ganglia/gmond.conf
  1. globals {                    

  2.   daemonize = yes  ##以后台的方式运行            

  3.   setuid = yes             

  4.   user = ganglia     #运行Ganglia的用户              

  5.   debug_level = 0               

  6.   max_udp_msg_len = 1472        

  7.   mute = no             

  8.   deaf = no             

  9.   host_dmax = 0 /*secs */ 

  10.   cleanup_threshold = 300 /*secs */ 

  11.   gexec = no             

  12.   send_metadata_interval = 10     #发送数据的时间间隔

  13. } 

  14. 

  15. /* If a cluster attribute is specified, then all gmond hosts are wrapped inside 

  16.  * of a <CLUSTER> tag.  If you do not specify a cluster tag, then all <HOSTS> will 

  17.  * NOT be wrapped inside of a <CLUSTER> tag. */ 

  18. cluster { 

  19.   name = "hadoop-cluster"         #集群名称

  20.   owner = "ganglia"               #运行Ganglia的用户

  21.   latlong = "unspecified" 

  22.   url = "unspecified" 

  23. } 

  24. 

  25. /* The host section describes attributes of the host, like the location */ 

  26. host { 

  27.   location = "unspecified" 

  28. } 

  29. 

  30. /* Feel free to specify as many udp_send_channels as you like.  Gmond 

  31.    used to only support having a single channel */ 

  32. udp_send_channel { 

  33.   #mcast_join = 239.2.11.71     #注释掉组播

  34.   host = master                 #发送给安装gmetad的机器

  35.   port = 8649                   #监听端口

  36.   ttl = 1 

  37. } 

  38. 

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

  40. udp_recv_channel { 

  41.   #mcast_join = 239.2.11.71     #注释掉组播

  42.   port = 8649 

  43.   #bind = 239.2.11.71 

  44. } 

  45. 

  46. /* You can specify as many tcp_accept_channels as you like to share 

  47.    an xml description of the state of the cluster */ 

  48. tcp_accept_channel { 

  49.   port = 8649 

  50. } 
复制代码

gmetad.conf
在主节点上还需要配置/etc/ganglia/gmetad.conf,这里面的名字hadoop-cluster和上面gmond.conf中name应该一致。　
/etc/ganglia/gmetad.conf
  1. sudo vim /etc/ganglia/gmetad.conf
复制代码
修改为以下内容
  1. data_source "hadoop-cluster" 10 master:8649 slave:8649

  2. setuid_username "nobody"

  3. rrd_rootdir "/var/lib/ganglia/rrds"

  4. gridname "hadoop-cluster"

  5. 注:master:8649 slave:8649为要监听的主机和端口,data_source中hadoop-cluster与gmond.conf中name一致
复制代码


4. Hadoop配置
在所有hadoop所在的节点，均需要配置hadoop-metrics2.properties，配置如下：

复制代码


5. Hbase配置
在所有的hbase节点中均配置hadoop-metrics2-hbase.properties,配置如下:
  1. # syntax: [prefix].[source|sink].[instance].[options]

  2. # See javadoc of package-info.java for org.apache.hadoop.metrics2 for details

  3. 

  4. #*.sink.file*.class=org.apache.hadoop.metrics2.sink.FileSink

  29. 

  30. 

  31. *.sink.ganglia.class=org.apache.hadoop.metrics2.sink.ganglia.GangliaSink31  

  32. *.sink.ganglia.period=10  

  33. 

  34. hbase.sink.ganglia.period=10  

  35. hbase.sink.ganglia.servers=master:8649
复制代码


6. 启动hadoop、hbase集群
  1. start-dfs.sh

  2. start-yarn.sh

  3. start-hbase.sh
复制代码


7. 启动Ganglia
先需要重启hadoop和hbase 。在各个节点上启动gmond服务，主节点还需要启动gmetad服务。
使用apt-get方式安装的Ganglia，可以直接用service方式启动。
  1. sudo service ganglia-monitor start（每台机器都需要启动）

  2. 

  3. sudo service gmetad start（在安装了ganglia-webfrontend的机器上启动）
复制代码


8. 检验
登录浏览器查看：http://master/ganglia，如果Hosts up为9即表示安装成功。
若安装不成功，有几个很有用的调试命令：
以调试模式启动gmetad：gmetad -d 9
查看gmetad收集到的XML文件：telnet master 8649

  1. # This is an example of a Ganglia Meta Daemon configuration file

  2. #                http://ganglia.sourceforge.net/

  3. #

  4. #

  5. #-------------------------------------------------------------------------------

  6. # Setting the debug_level to 1 will keep daemon in the forground and

  7. # show only error messages. Setting this value higher than 1 will make 

  8. # gmetad output debugging information and stay in the foreground.

  9. # default: 0

  10. # debug_level 10

  11. #

  12. #-------------------------------------------------------------------------------

  13. # What to monitor. The most important section of this file. 

  14. #

  15. # The data_source tag specifies either a cluster or a grid to

  16. # monitor. If we detect the source is a cluster, we will maintain a complete

  17. # set of RRD databases for it, which can be used to create historical 

  18. # graphs of the metrics. If the source is a grid (it comes from another gmetad),

  19. # we will only maintain summary RRDs for it.

  20. #

  21. # Format: 

  22. # data_source "my cluster" [polling interval] address1:port addreses2:port ...

  23. # 

  24. # The keyword 'data_source' must immediately be followed by a unique

  25. # string which identifies the source, then an optional polling interval in 

  26. # seconds. The source will be polled at this interval on average. 

  27. # If the polling interval is omitted, 15sec is asssumed. 

  28. #

  29. # If you choose to set the polling interval to something other than the default,

  30. # note that the web frontend determines a host as down if its TN value is less

  31. # than 4 * TMAX (20sec by default).  Therefore, if you set the polling interval

  32. # to something around or greater than 80sec, this will cause the frontend to

  33. # incorrectly display hosts as down even though they are not.

  34. #

  35. # A list of machines which service the data source follows, in the 

  36. # format ip:port, or name:port. If a port is not specified then 8649

  37. # (the default gmond port) is assumed.

  38. # default: There is no default value

  39. #

  40. # data_source "my cluster" 10 localhost  my.machine.edu:8649  1.2.3.5:8655

  41. # data_source "my grid" 50 1.3.4.7:8655 grid.org:8651 grid-backup.org:8651

  42. # data_source "another source" 1.3.4.7:8655  1.3.4.8

  46. rrd_rootdir "/var/lib/ganglia/rrds"

  49. #

  50. # Round-Robin Archives

  51. # You can specify custom Round-Robin archives here (defaults are listed below)

  52. #

  53. # Old Default RRA: Keep 1 hour of metrics at 15 second resolution. 1 day at 6 minute

  54. # RRAs "RRA:AVERAGE:0.5:1:244" "RRA:AVERAGE:0.5:24:244" "RRA:AVERAGE:0.5:168:244" "RRA:AVERAGE:0.5:672:244" \

  55. #      "RRA:AVERAGE:0.5:5760:374"

  56. # New Default RRA

  57. # Keep 5856 data points at 15 second resolution assuming 15 second (default) polling. That's 1 day

  58. # Two weeks of data points at 1 minute resolution (average)

  59. #RRAs "RRA:AVERAGE:0.5:1:5856" "RRA:AVERAGE:0.5:4:20160" "RRA:AVERAGE:0.5:40:52704"

  62. #-------------------------------------------------------------------------------

  63. # Scalability mode. If on, we summarize over downstream grids, and respect

  64. # authority tags. If off, we take on 2.5.0-era behavior: we do not wrap our output

  65. # in <GRID></GRID> tags, we ignore all <GRID> tags we see, and always assume

  66. # we are the "authority" on data source feeds. This approach does not scale to
