gtop

gtop is a lightweight terminal-based system monitoring dashboard for Linux, macOS, and Windows that displays real-time CPU, memory, and process metrics. It is installed via npm and runs as a command-line tool, offering an alternative to traditional system monitors like 'top' with a more modern terminal UI.

What gtop is

Written in JavaScript (Node.js >= v8), gtop provides a TUI (text user interface) for system resource monitoring with process sorting by PID, CPU, or memory usage. It requires host-level access to system metrics and can be containerized via Docker with appropriate net and pid namespace assignments.

Quickstart

Get the gtop source

Clone the repository and explore it locally.

terminalbash
git clone https://github.com/aksakalli/gtop.gitcd gtop# follow the project's README for install & configuration

Best use cases

Development environment monitoring

Quick system resource visibility during local development without switching to separate monitoring tools; useful for developers tracking process overhead.

Server performance triage

Lightweight on-demand monitoring via SSH or container access for rapid assessment of CPU/memory consumption without installing heavy agents.

Docker and containerized deployments

Official Docker image allows monitoring of containerized workloads with proper namespace configuration; useful in CI/CD pipelines or container orchestration debugging.

Implementation considerations

  • Requires Node.js v8 or later; verify runtime version in target environment.
  • Terminal encoding and color support may need explicit environment variables (LANG, TERM) on some systems per README troubleshooting.
  • For Docker deployment, must explicitly pass --net=host and --pid=host flags; requires elevated or privileged execution context.
  • Process sorting and display refresh is keyboard-driven; no batch/scripted data export for automation.
  • No built-in configuration file or programmatic API; interaction is CLI-only.

When to avoid it — and what to weigh

  • Enterprise-grade monitoring required — No alerting, historical data retention, centralized dashboards, or multi-host aggregation; better served by Prometheus, Datadog, or New Relic.
  • Windows as primary platform — README states only 'partial support' for Windows; Linux and macOS are primary targets.
  • Persistent metrics or audit trail — gtop is read-only and transient; it does not log, export, or persist metrics for compliance or historical analysis.
  • Low-maintenance long-term operations — Last release was August 2023 (v1.1.5) with 42 open issues; newer system kernels or Node.js versions may introduce compatibility gaps.

Security considerations

gtop requires access to /proc (Linux) or equivalent system APIs to read process and resource data; no authentication or encryption layer. When containerized, requires --pid=host and --net=host, which escalate container privileges. Review access controls and use only in trusted environments. No audit logging of data read. Regular updates recommended to address any kernel API changes.

Alternatives to consider

htop

Mature C-based alternative with broader platform support, more features, and active maintenance; terminal-based like gtop but without Node.js runtime dependency.

Prometheus + Grafana

Enterprise-grade monitoring with time-series storage, alerting, multi-host dashboards, and deep integrations; significant complexity trade-off for production use.

btop / bpytop

Modern terminal UI monitoring tools (C++ / Python) with lower resource footprint and richer visualizations than gtop; actively maintained.

gtop FAQ

Does gtop store or export metrics?
No. gtop is a real-time viewer only; it does not persist, log, or export metrics. For historical analysis or alerting, use a time-series database or monitoring platform.
Can I use gtop in production?
Not recommended as a primary monitoring solution. gtop is suitable for ad-hoc troubleshooting or lightweight dashboards. Production should use dedicated monitoring stacks (Prometheus, Datadog, etc.).
What are the resource overhead and runtime requirements?
gtop requires Node.js v8+. Overhead is low for a single-host tool; no background service. Startup time depends on npm resolution and Node.js interpreter load.
How does gtop compare to the 'top' command?
gtop provides a more modern, colored terminal UI and is installable via npm. 'top' is a native OS utility and lighter-weight; gtop trades a heavier runtime (Node.js) for usability.
