Parser for java garbage collection logs.
At least the output written by hotspot's -verbose:gc flag.
Your JVM died with OutOfMemoryError, ran depresingly slowly or perhaps with unpredictable latency.
The Java garbage collection handbook from Plumbr has an excellent write up of the concepts involved.
Use as a library from maven central:
<dependency>
<groupId>io.github.binaryfoo</groupId>
<artifactId>gclog-parser</artifactId>
<version>0.0.2</version>
</dependency>
Or Download as a command line tool to convert a garbage collection log to a .csv file.
Or use from lagotto to produce basic charts.
