JFR collects data from the JVM (through internal APIs) and from the Java application (through the JFR APIs). This data is stored in small thread-local buffers that are flushed to a global in-memory buffer. Data in the global in-memory buffer is then written to disk.

Stop a recording. The JFR.stop diagnostic command stops a running recording and has the option to discard the recording data. For example: thread_buffer_size: (Optional) Local buffer size for each thread in bytes if one of the following suffixes is not used: 'k' or 'K' for kilobytes or 'm' or 'M' for megabytes. Overriding this parameter could reduce performance and is not recommended.
