check-http-status

check-http-status is a CLI tool written in Go that monitors the HTTP status code of a specified website at regular intervals. It can log the results to a file and supports configurable timeouts and intervals.

Features

• Monitors HTTP status codes of a target URL.
• Configurable interval for sending requests.
• Optional logging of results to a file.
• Supports request timeouts to avoid hanging on unresponsive servers.
• Gracefully handles termination via Ctrl+C.

Sample output

Timestamp=2024-12-17_22-44-18, Response time=223.767ms, Status=200 OK
Timestamp=2024-12-17_22-44-28, Response time=99.739ms, Status=200 OK
Timestamp=2024-12-17_22-44-38, Response time=87.543ms, Status=200 OK

After interrupting by command+c, we can get summary:

----------Summary----------
Total Requests: 3
Successful Responses: 3 (100.00%)
Failed Responses: 0 (0.00%)
Average Response Time: 207.722333ms

Example

Monitor the HTTP status code of https://example.com every 30 seconds and log results to a file:

check-http-status https://example.com -i 30 -c

Flags

Flag	Shorthand	Description	Default
--interval-seconds	-i	Interval in seconds between HTTP requests.	10
--create-log-file	-c	Create a log file to save the results. The log file name format is check-http-status_<timestamp>.log.	false
--timeout-seconds	-t	Timeout in seconds for each HTTP request. If no response is received within this time, the request is considered failed.	30

Handling Interruptions

The tool handles interruptions gracefully. Press Ctrl+C to terminate the monitoring process.
