Java Management Extensions (JMX) is a Java technology that supplies tools to manage and monitor applications

§ Allows for instrumentation level access to the application§ JConsole is a example of a clients that can connect to the JVM and view application

internals such as heap usage, threads, running argument, etc.§ PATROL Agents installed with Apache Tomcat and Generic Java Server KM acts as a

client that can leverage the instrumentation of the JVM to collect performance data

What is JMX


Ø Health of the Java processes§ Monitoring Java processes from an OS only gives a high level overview of the

memory usage§ When monitoring is done from inside the JVM this allows for details like Heap

utilization %§ Keeping an eye on the JVM will help your application running smoothly

Ø TrueSight application load validation§ Java is the heart of TrueSight Operations Manager and must monitor for health§ Monitoring the heap usage with thresholds is key to know when memory

adjustments are needed or deployment of addition components§ Monitoring the heap also is a indicator that the load on the server is exceeding the

scale of a component

Why monitor Java memory utilization


Ø File locationIn TSPS 11, make updates in the following directories:

Linux: /TrueSightPServer/truesightpserver/conf/custom/Windows: \TrueSightPServer\truesightpserver\conf\custom\

Ø Instrument csr.conf by adding the following linesvm.args.system.520=-Dcom.sun.management.jmxremote.port=3333

vm.args.system.521=-Dcom.sun.management.jmxremote.ssl=falsevm.args.system.522=-Dcom.sun.management.jmxremote.authenticate=false

Ø Instrument idxsrv.conf by adding the following linesvm.args.system.520=-Dcom.sun.management.jmxremote.port=3334

vm.args.system.521=-Dcom.sun.management.jmxremote.ssl=falsevm.args.system.522=-Dcom.sun.management.jmxremote.authenticate=false

How to instrument TrueSight Presentation Server for Java Monitoring


NOTE: In TSPS 10.x and earlier, the files are located here:Linux: /TrueSightPServer/truesightpserver/conf/services/Windows: \TrueSightPServer\truesightpserver\conf\services\

Ø File locationMake updates in the following directories:

Linux: /usr/pw/custom/confWindows: ..\pw\custom\conf

Ø Instrument pnagentcntl.conf by uncommenting the following lineCOMDefine A=B -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9010 -Dcom.sun.management.jmxremote.local.only=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Djava.rmi.server.hostname=127.0.0.1

Ø Instrument pnjserver.conf by uncommenting the following lineCOMDefine A=B -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9020 -Dcom.sun.management.jmxremote.local.only=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Djava.rmi.server.hostname=127.0.0.1

Ø Instrument pnrate.conf by uncommenting the following linesCOMDefine com.sun.management.jmxremote.port=8686COMDefine com.sun.management.jmxremote.ssl=false

COMDefine com.sun.management.jmxremote.authenticate=false

How to instrument TrueSight Infrastructure Manager for Java Monitoring

© Copyright 2019 BMC Software, Inc.NOTE: In TSIM 10.x and earlier, these lines will need to be added to the files

Ø File locationMake updates in the following directories:

Linux: ../agent/custom/confWindows: ...\agent\custom\conf

Ø Copy the pnagent.conf file from pw/conf to pw/custom/confAfter copying the file remove all lines after #Fixed Section

Ø Instrument pnagent.conf by adding the following lines before the #Fixed Section

COMDefine com.sun.management.jmxremote.port=8989

COMDefine com.sun.management.jmxremote.ssl=falseCOMDefine com.sun.management.jmxremote.authenticate=false

How to configure TrueSight Infrastructure Manager Integration Services for Java Monitoring


Ø Deploy PATROL Agent and “Apache Tomcat and Generic Java Server” KM to each of the TSPS Servers
