This article explains what a deadlock is, demonstrates a simple Java deadlock example with code, outlines the four necessary conditions, and introduces four practical tools—jstack, jconsole, jvisualvm, and jmc—for diagnosing and resolving deadlocks in Java applications.
This guide walks through using JDK's native command‑line and GUI utilities—such as jps, jinfo, jvisualvm, jstat, jstack, and jcmd—to monitor JVM performance, inspect GC behavior, analyze thread dumps, and troubleshoot memory configuration problems in Java programs.
This article explains how to optimize Spring Boot's embedded Tomcat settings, tune JVM parameters, configure remote debugging in IDEA, and connect to JVM tools like JConsole and JVisualVM remotely, while also providing practical code snippets and deployment tips for backend services.
JVisualVM, bundled with JDK, provides a visual interface to monitor JVM threads, memory, and CPU usage, allowing installation of plugins for GC, thread, and memory analysis, demonstrating how to simulate memory leaks, capture heap dumps, compare snapshots, trace object references, and set up remote Tomcat monitoring via JMX.
This article explains how to conduct stress testing using JMeter, monitor Java applications with jconsole and jvisualvm, optimize gateway and microservice performance, improve database query speed with indexing, and tune garbage collection by enlarging the Eden space, providing step‑by‑step instructions and results.
This article introduces JVisualVM, explains how to install and use its plugins for monitoring threads, CPU, memory and GC, demonstrates a Java memory‑leak simulation with code and JVM options, shows step‑by‑step analysis of heap dumps, and describes remote Tomcat monitoring via JMX.
This guide introduces JVisualVM, explains its installation and plugin system, demonstrates how to create a memory‑leak example, use VisualGC and sampling tools to identify leaking objects, and shows step‑by‑step remote monitoring of a Tomcat server via JMX, providing practical screenshots and code snippets.
JVisualVM, bundled with JDK, offers a visual interface to monitor JVM threads, memory, CPU usage, and perform heap dumps, enabling developers to detect memory leaks, analyze object references, and remotely monitor applications such as Tomcat, with step-by-step installation, plugin usage, and code examples.
