jstat
is a command-line utility in the Java Development Kit (JDK) that provides monitoring and troubleshooting information about Java Virtual Machine (JVM) performance. It can display various statistics related to memory usage, garbage collection, and class loading, helping developers diagnose issues and optimize their applications. By using jstat
, you can gain insights into the JVM's behavior without needing to modify the application code.

In the context of JStat, "PAR" typically refers to parameters used in statistical models or analyses. It can denote a specific set of values that define the characteristics of a statistical distribution or model. Understanding these parameters is crucial for interpreting the results of statistical tests and models within JStat.
Well, honey, in the world of jstat, PAR stands for "Parallel GC" which is a garbage collector that runs in parallel with the application threads. It helps to improve garbage collection performance by utilizing multiple threads to clean up the trash. So, next time you see PAR in jstat, just remember it's there to help clean up the mess and keep things running smoothly.
In the context of the jstat command, which is used for monitoring Java Virtual Machine (JVM) statistics, "PRP" stands for "Promoted" space within the heap memory. It indicates the amount of memory that has been promoted from the Eden space to the old generation after garbage collection. This can help in assessing the efficiency of memory management and garbage collection processes in the JVM.
