Documentation
Comprehensive guide for monitoring and managing Java applications using the JMX Console platform.
Overview
What is JMX Console?
JMX Console provides an intuitive web-based interface for monitoring and managing Java applications using JMX (Java Management Extensions). It allows real-time oversight of system performance, configuration adjustments, and access to detailed diagnostic information.
Who Should Use It?
- System Administrators
- Java Developers
- Performance Engineers
Key Features
MBean Browser
Explore and interact with JMX MBeans in real-time. Access attributes, operations, and notifications for detailed diagnostics.
Dynamic Configuration
Modify application configurations on-the-fly using JMX operations without interrupting service operation.
Performance Monitoring
Visualize metrics such as heap usage, thread count, and GC pauses in real-time with interactive charts.
Security Management
Configure authentication and access control policies through secure JMX credentials and role-based management.
Metrics Dashboard
Visualize real-time JVM metrics including CPU, memory, and thread usage with animated data representations.
Remote Monitoring
Connect to remote Java applications securely using JMX remote connectors with encryption support.
Setup Guide
1. Enable JMX in Java Applications
java -Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=12345
-Dcom.sun.management.jmxremote.authenticate=true
-Dcom.sun.management.jmxremote.ssl=true
-Dcom.sun.management.jmxremote.ssl.config.file=ssl.config
-jar your-application.jar
2. Configure Authentication
Create a `jmxremote.access` file and `jmxremote.password` file with proper permissions.
MonitorUser readonly
AdminUser readwrite
3. Connect via JMX Console
Access the JMX Console web interface and enter your JMX connection details:
Host:
localhost
Port:
12345
Credentials:
AdminUser/password
