Uptime

Overview

The Uptime Component periodically checks if a site is up or down. It sends a message when the site's availability status changes (i.e., the site goes from up to down or vice versa).

Usage

Input Parameters

Parameter	Type	Description
target	string	The URL of the site to check for uptime. Must start with http:// or https://.

Output Ports

Port	Description
up	Triggered when the site becomes available. Returns the target URL, status code, and downtime details.
down	Triggered when the site becomes unavailable. Returns the target URL and status code.

Instructions

1. Set the Target URL

   • Provide a valid URL in the target field.

2. Monitoring Behavior

   • The component periodically checks the status of the target site.

   • If the site is down, it triggers the down port.

   • When the site comes back up, it triggers the up port with downtime duration details.

3. Ensure Proper Protocol

   • Only URLs with http:// or https:// are allowed.

Notes

• Status Codes Handling:

  • A 5xx response is considered a down status.

  • Successful responses indicate the site is up.

• State Persistence:

  • The component remembers the last known state of the site to detect status changes.

• Time Tracking:

  • When a site goes down, the downtime duration is recorded and sent once it comes back up.
