JConsole - able to monitor one service but not another

3351427Nov 22 2016 — edited Dec 12 2016

Hi,

I'm trying to monitor JVM for VMWare services using Jconsole.

I'm able to connect to one of the VMWare Java services by adding these parameters in wrapper.conf and server.xml. The other files in this folder are tomcat.version, tomcat-users.xml etc. This is the only VMWare service that has these tomcat files.

wrapper.java.additional.10="-Dcom.sun.management.jmxremote"

wrapper.java.additional.11="-Dcom.sun.management.jmxremote.port=1104"

wrapper.java.additional.12="-Dcom.sun.management.jmxremote.ssl=false"

wrapper.java.additional.13="-Dcom.sun.management.jmxremote.authenticate=false"

wrapper.java.additional.14="-Djava.rmi.server.hostname=11.168.x.x"

wrapper.java.additional.15="-Dcom.sun.management.jmxremote.rmi.port=1104"

I try to add the same above parameters in another VMWAre Java service which only has the wrapper.conf in its C:\Program Files\VMware\vCenter Server\vapi\wrapper\conf folder. The bin folder has wrapper.exe, heapsize_wrapper.bat, InstallApp-NT.bat and UnInstallApp-NT.bat

The same parameters doesn't work when trying to connect with Jconsole.

This is the log messages in jconsole for successful connection .

Also for the failure case,. this is displayed showing connection is successful.

PS U:\> netstat -an | Findstr 1102

TCP 0.0.0.0:1102 0.0.0.0:0 LISTENING

TCP 11.168.x.x:1102 11.248.x.x:61754 ESTABLISHED

TCP 11.168.x.x:1102 11.248.x.x:61755 ESTABLISHED

TCP [::]:1102 [::]:0 LISTENING

I have opened a case ticket with VMWare also for this issue, but they are unable to solve. I would like to dig deeper as to what might be the cause of this issue. I have doubt that somethings are not getting bound properly like hostname or port when the service starts,. I would like to know how I can find that out? Please let me know of any commands and your thoughts,.

Thanks,
