What This Dashboard Monitors
This dashboard tracks essential JVM runtime metrics to help you:
- Monitor CPU Performance: Track CPU utilization and processing time
- Analyze Memory Usage: Monitor heap, non-heap, and memory pool utilization
- Track Garbage Collection: Monitor GC frequency, duration, and performance impact
- Monitor Thread States: Track thread counts and states for concurrency analysis
- Class Loading: Monitor class loading and unloading patterns
- Performance Optimization: Identify bottlenecks and optimize JVM performance
- Resource Management: Monitor memory pools and garbage collection efficiency
Metrics Included
CPU Metrics
- CPU Count: Shows number of available CPU cores
- CPU Time: Shows JVM CPU time consumption over time
- CPU Recent Utilization: Shows recent CPU utilization percentage
Memory Metrics
- Heap Usage: Shows heap memory usage over time
- Non-Heap Usage: Shows non-heap memory usage over time
- Old gen size: Shows G1 Old Generation memory pool usage over time
- Eden size: Shows G1 Eden Space memory pool usage over time
- Survivor size: Shows G1 Survivor Space memory pool usage over time
Thread Metrics
- Timed waiting threads: Shows count of threads in timed waiting state over time
- Blocked threads: Shows count of threads in blocked state over time
- Daemon threads: Shows count of daemon threads over time
- Runnable threads: Shows count of threads in runnable state over time
- Live threads: Shows count of live (non-daemon) threads over time
Garbage Collection Metrics
- GC Major & Minor Collection Time (p90): Shows 90th percentile garbage collection duration for major and minor collections over time
- GC Major & Minor Collection Count: Shows rate of major and minor garbage collection events over time
- GC - Duration: Shows garbage collection duration percentiles (p50, p90, p99) in table format
- GC - p90 Duration: Shows 90th percentile garbage collection duration over time
Class Loading Metrics
- Classes loaded: Shows number of classes loaded over time
- Classes loaded: Shows number of classes unloaded over time (second graph)
