Thanks for your reply, Eric
I found the systemDataLoader.sh may be the new one like systemMetrics.sh in 0.3.0 And which shell is used to collect hadoop metrics in 0.3.0 I installed chukwa on one agent without hadoop environment, can i use systemMetrics.sh to collect system information with the configure to collect hadoop metrics, need to configure like 1. Copy CHUKWA_HOME/conf/hadoop-log4j.properties file to HADOOP_HOME/conf/log4j.properties 2. Copy CHUKWA_HOME/conf/hadoop-metrics.properties file to HADOOP_HOME/conf/hadoop-metrics.properties 3. Edit HADOOP_HOME/conf/hadoop-metrics.properties file and change @CHUKWA_LOG_DIR@ to your actual CHUKWA log dirctory (ie, CHUKWA_HOME/var/log) But when restart the start-mapred.sh , catch the exception log4j:ERROR Could not instantiate class [org.apache.hadoop.chukwa.inputtools.log4j.ChukwaDailyRollingFileAppender]. xx1-19: java.lang.ClassNotFoundException: org.apache.hadoop.chukwa.inputtools.log4j.ChukwaDailyRollingFileAppender xx1-19: at java.net.URLClassLoader$1.run(URLClassLoader.java:202) xx1-19: at java.security.AccessController.doPrivileged(Native Method) xx1-19: at java.net.URLClassLoader.findClass(URLClassLoader.java:190) xx1-19: at java.lang.ClassLoader.loadClass(ClassLoader.java:307) xx1-19: at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) xx1-19: at java.lang.ClassLoader.loadClass(ClassLoader.java:248) xx1-19: at java.lang.Class.forName0(Native Method) xx1-19: at java.lang.Class.forName(Class.java:169) But the daemon can still work, does this matter in running hadoop? 2010-03-03 00:58:17，"Eric Yang" <ey...@yahoo-inc.com> wrote： >Hi, > >/var/message is not stored into mysql.
