7.9.1 Overview of the output format of extended verbosegc information

The extended verbosegc information is output when a copy garbage collection occurs and also when a full garbage collection occurs.

When a copy garbage collection occurs, 'GC' is output as the type of garbage collection. When a full garbage collection occurs, 'Full GC' is output as the type of garbage collection. After the type, area-length-before-the-garbage-collection -> area-length-after-the-garbage-collection (allocated-area-size) is output for the respective areas.

Example of output of extended verbosegc information when a full garbage collection occurs is shown hereafter. The factors responsible for occurrence of the garbage collection and the CPU time of the GC thread are also output to the extended verbosegc information.

For details about the output format of the extended verbosegc information and the respective options, see 16. Start Option of JavaVM in the uCosminexus Application Server Definition Reference Guide.
