     13眾所周知， hadoop 是運行在分佈式的集群環境下，同是是許多用戶或者組共享的集群，因此任意時刻都會有很多用戶來訪問 NN 或者 JT ，對分佈式文件系統或者 mapreduce 進行操作，使用集群下的機器來完成他們的存儲和計算工作。當使用 hadoop 的用戶越來越多時，就會使得集群運維人員很難客觀去分析集群當前狀況和趨勢。比如 NN 的內存會不會在某天不知曉的情況下發生內存溢出，因此就需要用數據來得出 hadoop 當前的運行狀況。
     14
     15Chukwa 就是利用了集群中的幾個進程輸出的日誌，如 NN,DN,JT,TT 等進程都會有 log 信息，因為這些進程的程序裡面都調用 log4j 提供的接口來記錄日誌，而到底日誌的物理存儲是由 log4j.properties 的配置文件來配置的，可以寫在本地文件，也可以寫到數據庫。 Chukwa 就是來控制這些日誌的記錄，由 chukwa 程序來接替這部分工作，完成日誌記錄和採集工作。 Chukwa 由以下幾個組件組成：
     16
     17 || Agents ||  run on each machine and emit data. || 收集各個進程的日誌，並將收集的日誌發送給 collector ||
     18 || Collectors  ||   receive data from the agent and write it to stable storage.|| 收集 agent 發送為的數據，同時將這些數據保存到 hdfs 上 ||
     19 || MapReduce  jobs ||  parsing and archiving the data.|| 利用 mapreduce 來分析這些數據 ||
     20 || HICC || the Hadoop Infrastructure Care Center; a web-portal style interface for displaying data.|| HICC 將數據展現出來 ||
     21
     22 * !DumpTool 將結果下載保存到 mysql 數據庫
     23搭建、運行Chukwa要在Linux環境下，要安裝MySQL數據庫，在Chukwa/conf目錄 中有2個SQL腳本 aggregator.sql、database_create_tables.sq l 導入MySQL數據庫，此外還要有Hadoo的HDSF運行環境，

    123 Configuring and starting the Collector
    124 
    125    1. Copy conf/chukwa-collector-conf.xml.template to conf/chukwa-collector-conf.xml
    126    2. Edit conf/chukwa-collector-conf.xml and comment out the default properties for chukwaCollector.writerClass, and chukwaCollector.pipeline. Uncomment block for HBaseWriter parameters, and save.
    127    3. If you're running HBase in distributed mode, copy your hbase-site.xml file to the collectors conf/ directory. At a minimum, this file must contain a setting for hbase.zookeeper.quorum.
    128    4. Copy conf/chukwa-env.sh-template to conf/chukwa-env.sh.
    129    5. Edit chukwa-env.sh. You almost certainly need to set JAVA_HOME, HADOOP_HOME, HADOOP_CONF_DIR, HBASE_HOME, and HBASE_CONF_DIR at least.

    148191The local agent speaks a simple text-based protocol, by default over port 9093. Suppose you want Chukwa to monitor system metrics, hadoop metrics, and hadoop logs on the localhost:
    149192
    150193   1. Telnet to localhost 9093
    151    2.

     199   4. Type [without quotation marks] "add SocketAdaptor Hadoop 9096 0"
    160200   5. Type "list" -- you should see the adaptor you just started, listed as running.
    161201   6. Type "close" to break the connection.
    … …  
    164204      If you don't have telnet, you can get the same effect using the netcat (nc) command line tool.

    168208For data analytics with pig, there are some additional environment setup. Pig does not use the same environment variable name as Hadoop, therefore make sure the following environment are setup correctly:
    … …  
    170210   1. export PIG_CLASSPATH=$HADOOP_CONF_DIR:$HBASE_CONF_DIR
    171211   2. Setup a cron job for "pig -Dpig.additional.jars=${HBASE_HOME}/hbase-0.20.6.jar:${PIG_PATH}/pig.jar ${CHUKWA_HOME}/script/pig/ClusterSummary.pig" to run periodically
    172 
    173 Set Up HICC
    174 
    175 The Hadoop Infrastructure Care Center (HICC) is the Chukwa web user interface. To set up HICC, do the following:
    176 
    177    1. bin/chukwa hicc

    179 Data visualization
    180 
    181    1.
    182 
    183       Point web browser to http://localhost:4080/hicc/jsp/graph_explorer.jsp
    184    2. The default user name and password is "demo" without quotes.
    185    3. System Metrics collected by Chukwa collector will be browsable through graph_explorer.jsp file.
