What is Uptime Monitor?
The Uptime Monitor is a technical utility designed for developers and system administrators who need to track the health and responsiveness of web services. By utilizing standard system tools, this skill provides granular metrics on the various stages of an HTTP request, including DNS lookup, TCP connection, and TLS handshake timings. Integrating this into your collection of Openclaw Skills empowers your AI agent to perform real-time diagnostic checks and maintain high availability for critical infrastructure.
Uptime Monitor Use Cases
- Real-time monitoring of production website availability.
- Benchmarking server latency across different environments or geographic regions.
- Automated bulk health checks for a list of service endpoints.
- Debugging slow response times by isolating DNS or TLS handshake delays.
- Generating periodic status reports for stakeholder communication.
How Uptime Monitor Works
- The user specifies a target URL or a set of URLs to investigate.
- The skill executes a curl command configured with specific write-out variables to capture detailed timing data.
- The tool follows redirects automatically to ensure the final destination is reachable.
- For bulk or repeated checks, the skill iterates through the targets and records HTTP status codes and total durations.
- The results are analyzed against latency thresholds to categorize the site as Up, Slow, or Down.
- A structured Markdown report is produced, summarizing the performance of all monitored endpoints.
Uptime Monitor Setup
The Uptime Monitor requires curl to be installed on your system. No external API keys or complex dependencies are needed, making it one of the most portable Openclaw Skills available.
# Basic command to check a single URL with timing metrics
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" -L --max-time 10 https://example.com
Uptime Monitor Data Schema & Taxonomy
The skill organizes monitoring data into a clear tabular format for easy analysis:
| Field | Description |
|---|---|
| URL | The web address being monitored. |
| Status | The health state (🟢 Up, 🟡 Slow, 🔴 Down). |
| Code | The HTTP status code (e.g., 200, 404, 500). |
| DNS | Duration of the DNS resolution phase. |
| Connect | Duration of the TCP connection phase. |
| TLS | Duration of the SSL/TLS handshake phase. |
| Total | The cumulative time taken for the entire request. |
Performance Thresholds:
- 🟢 Up: Response time < 1s
- 🟡 Slow: Response time between 1s and 3s
- 🔴 Down: Response time > 3s or connection error.
Uptime Monitor Advanced Features
- Bulk monitoring capabilities for checking multiple URLs in a single execution.
- Configurable timeout settings using the --max-time flag to prevent agent hang-ups.
- Repeated monitoring loops with customizable intervals for continuous tracking.
- Detailed error identification, distinguishing between DNS failures and HTTP errors.
- Redirect tracking to ensure that health checks reach the final intended destination.
