Collect and monitor general performance metrics of Jetty application server
Usage protocol: JMX
Pre-monitoring Operations
You need to enable the
JMX
service in the JVM application. HertzBeat uses the JMX protocol to collect metrics for the JVM.
Jetty application server opens JMX protocol steps
Refer to official documentation
Start the JMX JMX-REMOTE module in Jetty
java -jar $JETTY_HOME/start.jar --add-module=jmx
java -jar $JETTY_HOME/start.jar --add-module=jmx-remoteSuccessful command execution will create
${JETTY_BASE}/start.d/jmx-remote.ini
configuration fileEdit the
${JETTY_BASE}/start.d/jmx-remote.ini
configuration file to modify the JMX IP port and other parameters.localhost
needs to be modified to expose the IP## The host/address to bind the RMI server to.
# jetty.jmxremote.rmiserverhost=localhost
## The port the RMI server listens to (0 means a random port is chosen).
