Constructor Detail

UnifiedG1GCParser

public UnifiedG1GCParser()

Method Detail

eventsProduced

public Set<EventSource> eventsProduced()

Specified by:

eventsProduced in interface DataSourceParser

getName

public String getName()

Specified by:

getName in class GCLogParser

process

protected void process(String line)

Specified by:

process in class GCLogParser

endOfFile

public void endOfFile(GCLogTrace trace,
                      String line)

heapSize

public void heapSize(GCLogTrace trace,
                     String line)

heapRegionSize

public void heapRegionSize(GCLogTrace trace,
                           String line)

other

public void other(GCLogTrace trace,
                  String line)

evacuateCSetPhase

public void evacuateCSetPhase(GCLogTrace trace,
                              String line)

postEvacuatePhaseDuration

public void postEvacuatePhaseDuration(GCLogTrace trace,
                                      String line)

toSpaceExhausted

public void toSpaceExhausted(GCLogTrace trace,
                             String line)

parallelCount

public void parallelCount(GCLogTrace trace,
                          String line)

regionSummary

public void regionSummary(GCLogTrace trace,
                          String line)

The trace indicates number of active regions before and after the collection. This is then used to provide an extremely coarse estimate of the amount of live data.

Parameters:

trace - A chunk of GC log that we are attempting to match to a known GC log pattern

line - The log line corresponding to the trace

unifiedMetaData

public void unifiedMetaData(GCLogTrace trace,
                            String line)

youngDetails

public void youngDetails(GCLogTrace trace,
                         String line)

metaNonClassClassSpace

public void metaNonClassClassSpace(GCLogTrace trace,
                                   String line)

Record contains Metaspace broken out to class and non-class space. Since Metaspace = class space + non-class space, we can ignore the non-class space information (for now) The space size before the collection can be determined by inspecting the previous record (ignore for now)

Parameters:

trace - A chunk of GC log that we are attempting to match to a known GC log pattern

line - The log line corresponding to the trace

accepts

public boolean accepts(Diary diary)

Specified by:

accepts in interface DataSourceParser

publishTo

public void publishTo(JVMEventChannel bus)

Specified by:

publishTo in interface DataSourceParser

Overrides:

publishTo in class GCLogParser
