Description
A new GC performance counter has been added for pauses during the concurrent phase. This counter will be listed by `jstat` under the CGC (concurrent GC) heading. This information is only available for GCs with a concurrent phase and is GC specific: * G1 includes remark and cleanup pauses * CMS includes initial mark and remark pauses For CMS, these pauses were previously included in the time listed by `jstat` under the FGC (full GC) heading. The information is also available via the `jcmd` by using `PerfCounter.print`.
