GCViewer is a Java-based tool that visualizes and summarizes verbose garbage collection logs from Sun/Oracle, IBM, HP, and BEA JVMs, including modern G1 and unified logging formats. It offers both a Swing GUI and a command-line mode that produces CSV summaries and chart images.
Use cases
- analyze java garbage collection logs
- visualize gc pause times and heap usage
- generate a csv summary from gc.log
- tune jvm garbage collector performance
- parse g1 collector logs
- chart gc activity from rotated log files
When to choose
- you need to diagnose GC pauses or memory pressure in a JVM application
- you want a free, offline tool to parse verbose:gc or -Xlog:gc output
- you need command-line GC log reports for automation
When to avoid
- you need real-time GC monitoring or alerting in production
- you use a JVM or logging format not listed as supported
- you want a modern web-based APM solution
