Overview#
This page describes how to use JProfiler Java Profiler on PKI server.
Installing JProfiler#
Download JProfiler:
$ wget https://download-gcdn.ej-technologies.com/jprofiler/jprofiler_linux_11_1_2.rpm
$ dnf install ./jprofiler_linux_11_1_2.rpm
JProfiler will be installed in /opt/jprofiler11 folder.
Alternatively:
$ wget https://download-gcdn.ej-technologies.com/jprofiler/jprofiler_linux_11_1_2.sh
$ sh jprofiler_linux_11_1_2.sh
JProfiler will be installed in ~/jprofiler11 folder.
Running JProfiler#
To run JProfiler:
$ /opt/jprofiler11/bin/jprofiler
Enabling JProfiler Agent#
Select a port for JProfiler agent (e.g. 8849). If SELinux is enabled, enable the SELinux port:
$ semanage port -a -t http_port_t -p tcp 8849
In PKI 10.9 or later, to run the server with JProfiler agent:
$ pki-server run --agentpath /opt/jprofiler11/bin/linux-x64/libjprofilerti.so=port=8849
JProfiler> Listening on port: 8849.
JProfiler> Enabling native methods instrumentation.
JProfiler> Can retransform classes.
JProfiler> Can retransform any class.
JProfiler> Native library initialized
JProfiler> VM initialized
JProfiler> Waiting for a connection from the JProfiler GUI ...
It will run the server in foreground.
Alternatively, edit /etc/sysconfig/pki-tomcat and define the JProfiler agent as follows:
JAVA_OPTS="-agentpath:/opt/jprofiler11/bin/linux-x64/libjprofilerti.so=port=8849,nowait"
Then restart the systemd service. If the service fails to start, check the systemd journal for errors.
Connecting to PKI Server#
Once the server is started, in JProfiler open Start Center -> Quick Attach, select On another computer. Select Direct connection to, then enter the hostname and JProfiler port.
