grapicli

A command-line tool for querying the Graylog REST API, built with Typer and Rich.

Features

• 🔍 Search logs by source host, message content, or any combination
• 🕐 Flexible time ranges — relative (last N minutes) or absolute (--since / --until)
• 📋 Configurable result limits with --limit
• 🔑 Token-based authentication loaded automatically from a .env file
• 🖥️ Rich terminal output — results displayed in a colour-coded table

Installation

pip install grapicli

Or with Poetry:

poetry add grapicli

Configuration

Create a .env file in your working directory (or project root) with your Graylog credentials:

export GRAYLOG_URL=https://your-graylog-server
export GRAYLOG_TOKEN=your_api_token_here

Note: Never commit your .env file to version control.

Finding your API token

1. Log in to the Graylog web interface.
2. Go to System → Users and Teams → Edit Profile → API Tokens.
3. Create a new token and copy the value into your .env file.
