I'm trying to install HPjmeter console on centos 7 desktop in order to monitor my web app GC status . I've follwed all the steps mentioned on the official user guide but when executing this command line in order to launch the console:

/opt/hpjmeter/bin/hpjmeter

I'm getting this message:

Please check that a display is available and the appropriate display variable is set

I changed the value of $DISPLAY variable as localhost:0.0 but still getting the same message.

can any one help me please to fix it.

Thanks
