How can I block Apache Ignite message "Possible too long JVM pause" in output console?-CodePudding

While debugging I'm flooded with this messages. More in general it is something I don't want in my development environment, while it's fine to have it in prod.

How can I disable such messaging?

2021-10-13 10:11:48.973  WARN 5072 --- [detector-worker] org.apache.ignite.internal.IgniteKernal  : Possible too long JVM pause: 1121 milliseconds.

CodePudding user response：

I can see that you have solved your problem, but the question remains relevant so I will answer anyway.

The warnings come from LongJVMPauseDetector and can be suppressed by changing the logging configuration to ERROR for the logger for that class. A better option would be to increase the threshold for when to warn. Set the system property IGNITE_JVM_PAUSE_DETECTOR_THRESHOLD to something higher than the default 500 ms, for example 120000 for 120 seconds. That will get rid of the unwanted warnings (unless you pause for more than two minutes, of course).
