## What it is
jvmtop is a lightweight top-like console application that monitors all accessible running JVMs on a machine, displaying JVM internal metrics such as heap memory, CPU, and GC usage. It also includes a console CPU profiler for Java processes.

## Use cases
- monitor all running java processes on a server from the terminal
- find which jvm is consuming the most cpu
- profile a java application's cpu usage from the command line
- watch heap memory usage of a tomcat or resin instance
- debug gc activity across multiple jvms
- quickly inspect jvm metrics without a gui

## When to choose
- you need a lightweight, terminal-based alternative to jconsole or visualvm
- you want a top-like view of all JVMs on a Linux, Solaris, FreeBSD, or Windows host
- you need a quick console CPU profiler without installing heavy tooling

## When to avoid
- you need rich GUI dashboards, historical charts, or alerting
- you only have a JRE installed - a full JDK is required
- you need actively maintained tooling with recent fixes and modern JDK support

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: monitoring, benchmarking, developer-tools, terminal-ui
- domain: developer-tools, monitoring, performance
- platform: windows, cli, jvm
- tags: jvm-monitoring, profiler, top-like, java-processes, console-profiler, command-line, linux, macos
