In default/profile configurations for the events we have these:
<event name="jdk.JavaMonitorInflate">
<setting name="enabled">false</setting>
<setting name="stackTrace">true</setting>
<setting name="threshold" control="locking-threshold">20 ms</setting>
</event>
There is a threshold for inflate event. But the operation that is covered by that event is very fast, and often lock-free, so the threshold would filter many events. This would be important as we add deflation event (JDK-8351142), which should match inflations.
