Uptime Tool — System Uptime & Load Monitor

Display how long the system has been running since last boot, current user sessions, and CPU load averages. Essential for health checks, reboot verification, and capacity monitoring.

Quick Start

# Show system uptime
uptime-tool

# Show uptime plus JSON output for monitoring
uptime-tool --json

Usage

uptime-tool [OPTIONS]

Options:
  --json       Output as structured JSON
  --pretty     Human-readable format with emojis (default)
  --since      Show boot time timestamp
  --seconds    Show uptime in seconds only
  --compare    Compare with last-known value (requires --state-file)
  --watch N    Monitor continuously, N second intervals
  --alert N    Alert if uptime < N seconds (short uptime = recent reboot)

Examples

# Standard uptime output
uptime-tool

# Machine-readable JSON for monitoring
uptime-tool --json

# Show boot time
uptime-tool --since

# Watch every 30 seconds
uptime-tool --watch 30

# Alert if system just rebooted (< 60 seconds uptime)
uptime-tool --alert 60

# Uptime in seconds for scripts
uptime-tool --seconds
