Monitoring tools are not included in JRE so if you can’t install a JDK the following files can be copied to the JRE.
Note! The JDK must match the JRE version.
All platforms
<JDK_ROOT>/lib/tools.jar –> <JRE_ROOT>/lib/tools.jar <JDK_ROOT>/lib/jconsole.jar –> <JRE_ROOT>/lib/jconsole.jar
Ubuntu 12.04
<JDK_ROOT>/jre/lib/amd64/libattach.so –> <JRE_ROOT>/bin/libattach.so <JDK_ROOT>/bin/jconsole –> <JRE_ROOT>/bin/jconsole <JDK_ROOT>/bin/jmap –> <JRE_ROOT>/bin/jmap <JDK_ROOT>/bin/jps -> <JRE_ROOT>/bin/jps
Windows
<JDK_ROOT>\bin\jconsole.exe –> <JRE_ROOT>\bin attach.dll – <JRE_ROOT>\bin jmap.exe – <JRE_ROOT>\bin jps.exe - <JRE_ROOT>\bin
