Enabling Jmx for Tomcat

Create (or append to) the file /opt/mas/tomcat/bin/setenv.sh

#!/bin/sh CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote.port=1701 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.local.only=false \  -Dcom.sun.management.jmxremote.password.file=/opt/mas/jmx/tomcat.password -Dcom.sun.management.jmxremote.access.file=/opt/mas/jmx/jmx.access"

then run the following commands:

chown tomcat:tomcat /opt/mas/jmx/tomcat.password /opt/mas/tomcat/bin/setenv.sh /etc/init.d/tomcat_8080 stop /etc/init.d/tomcat_8080 start

Enable JMX metrics for Spark.

Steps to enable JMX metrics for Spark.

1. For basic JVM metrics, append the following line to the file /etc/spark/conf.mas/spark-env.sh:

# Enable HistoryServer JMX connections on port 9991

HADOOP_JOB_HISTORYSERVER_OPTS="-Dcom.sun.management.jmxremote.port=9991 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.local.only=false -Dcom.sun.management.jmxremote.password.file=/opt/mas/jmx/mapred.password -Dcom.sun.management.jmxremote.access.file=/opt/mas/jmx/jmx.access"

2. For Spark Mater webUI update spark-env.sh

           export SPARK_MASTER_WEBUI_PORT=18080

       3.   For more metrics update metrics.properties

*.sink.jmx.class=org.apache.spark.metrics.sink.JmxSink

*.source.jvm.class=org.apache.spark.metrics.source.JvmSource

Configuring Zabbix Monitoring For All Hadoop Services (Zookeeper,Spark, namenode, datanode , job history server , hdfs journal node, hive and HBase)

Below info document Zabbix monitoring configuration for all Hadoop services like Zookeeper,Spark, namenode, datanode , job history server , hdfs journal node, hive and HBase with respect file changes.

For Zookeeper:
vi /etc/default/zookeeper
export SERVER_JVMFLAGS="-Dcom.sun.management.jmxremote.port=1703 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.password.file=/opt/shekhar/jmx/zookeeper.password -Dcom.sun.management.jmxremote.access.file=/opt/shekhar/jmx/jmx.access"
---------------------------------
Spark:
vi /etc/spark/conf/metrics.properties
*.sink.jmx.class=org.apache.spark.metrics.sink.JmxSink
*.source.jvm.class=org.apache.spark.metrics.source.JvmSource
---------------------------------
For namenode, datanode and job history server and hdfs journal node:
vi /etc/hadoop/conf/hadoop-env.sh
