5 Aug 2019 Most Java sampling profilers rely on "Java Virtual Machine Tool Interface (JVM as a call tree. jfr: Java Flight Recording with Method Profiling Sample events ( Thread Local Allocation Buffer) callbacks, which ca

the JFR run time stores the event data in thread-local buffers, eliminating the need to synchronize between threads for every event, which greatly improves throughput. Once a thread-local buffer has been filled, the data is transferred to a global buffer. When this happens, synchronization is necessary

Overriding this parameter could reduce performance and is not recommended. Long. 8192. threadbufferstodisk. Flag for allowing thread buffers to write directly to disk if the buffer thread is blocked.

So whenever we collect the thread dump then we should collect at least 5-6 thread dumps. In some interval like collect 5-6 thread dumps in 10 seconds interval. Like that we will get around 5-6 thread dumps in 1 minute.
