Overview
dtop is a blazing-fast Rust terminal dashboard for monitoring Docker containers across multiple hosts in real time. Built with Ratatui and Bollard, dtop delivers instant visibility into live CPU, memory, disk I/O, health checks, log streaming, container lifecycle actions (start/stop/remove), multi-host SSH/TLS support, tmux/Rex split panes (--panes), and deep Dozzle hyperlink integration without leaving your shell.
How It Works
dtop operates through structured, deterministic execution stages:
Multi-Host Docker Ingestion: Connects concurrently to local Docker Unix sockets, remote SSH tunnels, and mutual-TLS TCP endpoints without requiring the Docker CLI binary on the host.
Real-Time Ratatui Terminal Interface: Renders high-frequency CPU, memory, and container status telemetry in an interactive TUI at native terminal refresh rates with Nerd Font icons.
Split Pane Shell & Log Streaming: Launches native
--panes interactive container shells and live log streams in side-by-side tmux or Rex windows without disrupting the main monitor list.Dozzle Hyperlink Integration: Binds container names to clickable OSC 8 terminal hyperlinks, jumping directly to web log views with a single keystroke over remote SSH.

Key Technical Features & Capabilities
Real-Time Multi-Host Telemetry: Aggregates local Unix sockets,
ssh:// remote tunnels, tcp://, and mutual-TLS (tls://) hosts concurrently inside one crisp terminal UI.**Native Shell & Log Panes (
--panes)**: Spawns container interactive shells and live log streams in a side-by-side tmux or Rex terminal pane while preserving the container table view.Clickable OSC 8 Dozzle Hyperlinks: Renders container names as clickable links (
--hyperlinks auto) pointing directly to host Dozzle instances even over nested SSH sessions.Nerd Font Icons, Self-Update & Zero-Setup Config: Detects terminal glyph capability automatically (Ghostty, WezTerm, Rex, kitty), supports YAML filter rules, and updates cleanly via
dtop update.Architecture & Technology Stack

How to Use & Workflow
1
Launch Terminal Dashboard: Run
dtop locally or pass multiple remote endpoints: dtop --host local --host ssh://user@prod-server.2
Filter & Sort Workloads: Sort live by CPU, memory, uptime, or name (
-s cpu), apply stacked label/status filters (-f status=running), or press a for stopped containers.3
Inspect Logs & Shells in Panes: Run
dtop --panes inside tmux or Rex to pop interactive shell and log streams into an adjacent pane without blocking metrics.4
Update Binary: Execute
dtop update to check GitHub Releases and swap the binary in place safely.How to Use & Workflow

Troubleshooting & Common Issues
Issue: Icons render as empty boxes or replacement question marks.
*Cause*: Terminal emulator lacks a Nerd Font and could not auto-negotiate native glyphs.
*Resolution*: Install a Nerd Font or launch with
dtop --icons unicode (or set icons: unicode in config).**Issue:
--panes shell lacks DOCKER_HOST variables inside existing tmux session.***Cause*: tmux splits inherit the tmux server's global environment rather than transient shell exports.
*Resolution*: Pass target endpoints explicitly on launch via
dtop --panes --host ssh://user@host.How to Use & Getting Started
