Features Overview

Runtime Monitoring

Besides logging this is the second main task of JMyra. It allows you to

• List all threads groups and all running threads
• View all defined system properties
• Look up where your classes are loaded from. This feature is especially useful if you suspect that your classes are loaded from an outdated jar-file.
• An InstanceCounter API helps you to keep track of the number of instances of your classes. You can take snapshots of the counts and compare them over time.
• Graphical runtime statistics like heap memory usage help you discover problems early.

A statistic API lets you generate statistic events in your application and write listeners to process these statistics. In JMyra Enterprise Edition you can use predefined listeners to graphically display your statistics online.

JMyre Enterprise Edition can also generate and graphically display system statistics like the utilization of the VM heap memory or the number of running threads.

Watchdog Threads

A set of watchdog threads can be started to monitor free memory and number of threads.
