gping — real-time ping graph

💬 "gping command"

gping is a real-time ping graph that visualizes ping response times as a live graph. See latency trends at a glance inside your terminal.

Renders real-time graphs in your terminal using ANSI. Monitors multiple hosts simultaneously.

• Concept: Renders real-time graphs in your terminal using ANSI.
• Key Features: Monitors multiple hosts simultaneously.
• Advantage: Displays markers on the graph when a ping fails.
• Usage: Supports TCP ping (measuring latency per port).

Installation and Download

gping can be installed via a package manager or the official script.

To verify the installation, use gping --version.

Commonly Used Options

3 Essential Command Combinations

• gping google.com — Basic ping graph
• gping 8.8.8.8 1.1.1.1 — Compare both DNS servers
• gping --tcp myserver.com 443 — Check HTTPS port response latency

💬 "Show me an example of using gping on an actual server"

Here is a step-by-step breakdown of a common situation encountered on production servers.

Step 1 · Verify Installation

Check if it is installed.

gping --version || cargo install gping

Step 2 · Compare DNS

Spin up both DNS servers.

gping 8.8.8.8 1.1.1.1

Step 3 · Port Ping

Add a port ping to the target server.

gping --tcp myserver.com 443

Actual Execution Screen

This is the ping graph comparing both DNS servers.

How It's Used in Practice

1. Identifying Network Bottlenecks

Situation — Compare the gateway, DNS, and target simultaneously.

gping 8.8.8.8 1.1.1.1

Result — If only the gateway is slow, it's a VPN issue; if only the target is slow, it's a remote server issue.

Key Point — Narrow down the cause by comparing multiple targets.

2. Catching Intermittent Disconnections

Situation — Record network disconnections at night.

gping --tcp myserver.com 443

Result — Disconnection times and graph markers are recorded.

Key Point — Run it inside tmux for continuous monitoring.

Actual Execution Screen

This graph shows port latency checked via TCP ping.

Points of Caution

• gping uses ICMP or TCP ping. If ICMP is blocked by a firewall, the graph will be empty.
• If the terminal width is narrow, the graph resolution will decrease. A minimum of 60 columns is recommended.
• TCP ping only checks port response, unlike ICMP ping. A successful ping does not mean all ports are open.
