Chamado Health

Simple health check script for Healthchecks.io, designed to run every minute using a systemd timer.

Installation

1. Copy the systemd unit files to /etc/systemd/system/:

   sudo cp systemd/chamado-health.service /etc/systemd/system/
   sudo cp systemd/chamado-health.timer /etc/systemd/system/
   

2. Update the HEALTHCHECK_URL in the service unit or set it in /etc/default/chamado-health.

3. Reload systemd and enable the timer:

   sudo systemctl daemon-reload
   sudo systemctl enable --now chamado-health.timer
   sudo systemctl status chamado-health.timer
   

Configuration

• HEALTHCHECK_URL must be set to your Healthchecks.io ping endpoint.

• You can also pass the URL as a command-line argument to the script:

  ./healthcheck.py https://hc-ping.com/<your-uuid>
  

Script behavior

• Sends an HTTP GET to the configured Healthchecks.io URL.
• Exits with code 0 when the request succeeds with 2xx.
• Logs diagnostic errors to journal if the request fails.
