Chamado Health

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

Installation

Run the setup script:

bash setup.sh

The script will:

Ask for your HEALTHCHECK_URL (Healthchecks.io ping endpoint) and validate it.
Ask for a DEVICE_NAME to identify this machine.
Clone the repository to ~/src/health-monitor.
Save the configuration to ~/.config/health-monitor.
Install and enable the systemd timer via install_systemd.sh.
Run a test ping to confirm everything works.

Both HEALTHCHECK_URL and DEVICE_NAME can be pre-set as environment variables to skip the interactive prompts.

Configuration

The configuration file is ~/.config/health-monitor:

HEALTHCHECK_URL=https://hc-ping.com/<your-uuid>
DEVICE_NAME=my-machine

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

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

Systemd units

The unit files installed to ~/.config/systemd/user/ are:

health-check.service
health-check.timer

To reload and restart after changes:

systemctl --user daemon-reload
systemctl --user restart health-check.timer
systemctl --user list-timers --all | grep health-check
journalctl --user -u health-check.service -n 10 --no-pager

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.
