The article outlines JVM tuning fundamentals, categorizing common issues, presenting six optimization principles, detailing key JVM parameters, and introducing the jps command‑line tool to help developers diagnose and improve Java application performance while maintaining stability.
This guide explains how to use JDK command-line utilities such as jps, jstat, jinfo, jmap, jhat, and jstack to monitor JVM processes, inspect memory usage, generate heap dumps, and diagnose performance issues, providing command syntax, options, and practical examples.
This article introduces the jps tool for listing Java processes, explains its common options and usage examples, then provides a detailed overview of jstack, including its purpose, command syntax, thread‑state definitions, sample outputs, and practical tips for detecting deadlocks, counting threads, and diagnosing high CPU usage in Java applications.
This guide explains where Java's command‑line tools reside, why they are small wrappers around tools.jar, and provides detailed usage, options, and examples for the most common diagnostics utilities—including jps, jstat, jinfo, jmap, jhat, and jstack—helping developers monitor and troubleshoot JVM processes effectively.
This tutorial explains the three main categories of JVM parameters—standard, X, and XX—demonstrates how to view, modify, and verify them using command‑line tools such as java, jps, and jinfo, and provides step‑by‑step hands‑on labs for each type.
This guide introduces essential JVM performance monitoring tools—including jps, jstack, jmap, jhat, jstat, and hprof—explains their command syntax, demonstrates step‑by‑step usage with real‑world examples, and shows how to interpret their output to diagnose memory leaks, thread issues, GC behavior, and CPU hotspots.
This article introduces the most common JVM performance problems in enterprise Java applications and provides a practical guide to using core monitoring and tuning tools such as jps, jstack, jmap, jstat and hprof, complete with command syntax, sample outputs and step‑by‑step troubleshooting examples.
