MyPerf4J is a high-performance Java application performance monitoring (APM) tool implemented as a non-intrusive JavaAgent using ASM bytecode instrumentation. It collects per-method response time metrics (RPS, TP50-TP100 percentiles) and JVM metrics in real time with second-level granularity and minimal overhead.
Use cases
- monitor java application performance without code changes
- find performance bottlenecks in high-concurrency java services
- collect jvm metrics like gc, memory and threads in real time
- profile method response times with percentile statistics
- export java metrics to influxdb and grafana dashboards
- diagnose latency issues in low-latency microservices
When to choose
- you need zero-intrusion javaagent-based monitoring with nanosecond-level recording overhead
- you want second-level, full-coverage response time statistics for java methods
- you prefer a lightweight alternative to heavyweight APM suites
When to avoid
- you need distributed tracing across services rather than single-JVM metrics
- your stack is not on the JVM
- you require a full commercial APM with alerting and UI out of the box
