Uptime Monitor

Check website availability and performance.

Capabilities

  • Uptime Check: Verify if a website is up or down
  • Response Time: Measure DNS, connect, TLS, and total response times
  • Status Codes: Report HTTP status codes and redirects
  • Bulk Check: Monitor multiple URLs at once
  • History: Repeated checks over time with summary

Usage

Ask the agent to:

  • "Is example.com up?"
  • "Measure response time for mysite.org"
  • "Check these 5 URLs and report status"
  • "Monitor api.example.com every 30 seconds for 5 minutes"

How It Works

Uses curl with timing output:

curl -o /dev/null -s -w "HTTP %{http_code} | DNS: %{time_namelookup}s | Connect: %{time_connect}s | TLS: %{time_appconnect}s | Total: %{time_total}s\n" https://example.com

Requirements

  • curl (pre-installed on most systems)
  • No API keys needed
