JDK-6933402 - RFE: Improve PrintSafepointStatistics output to track cleanup time
Description
Customer complains seeing long application stop time and want to know more details about how that was introduced. We speculate that might be due to long safepoint. However, the log file from PrintSafepointStatistics does not give sufficient information regarding that. Particularly for clean up tasks such as deflate the contended monitors. It would be more useful to print out that data along with the current safepoint statistics. Also, give out the maximum vm operation time might also be helpful.
Comments
EVALUATION I forgot this RFE completely and filed another one 6933402. So close this one.
