# Chamado Health
|
|
|
|
Simple health check script for Healthchecks.io, designed to run every minute using a systemd timer.
|
|
|
|
## Installation
|
|
|
|
### 1. Install Git
|
|
|
|
```bash
|
|
# Debian/Ubuntu
|
|
sudo apt update && sudo apt install -y git python3
|
|
|
|
# RHEL/CentOS/Fedora
|
|
sudo dnf install -y git python3
|
|
```
|
|
|
|
### 2. Configure Git identity
|
|
|
|
```bash
|
|
git config --global user.name "Your Name"
|
|
git config --global user.email "you@example.com"
|
|
```
|
|
|
|
### 3. Clone the repository
|
|
|
|
```bash
|
|
mkdir -p ~/src
|
|
git clone https://github.com/SantosFC/health-check.git ~/src/health-check
|
|
cd ~/src/health-check
|
|
```
|
|
|
|
### 4. Run the setup script
|
|
|
|
```bash
|
|
bash setup.sh
|
|
```
|
|
|
|
The script will:
|
|
1. Ask for your `HEALTHCHECK_URL` (Healthchecks.io ping endpoint) and validate it.
|
|
2. Ask for a `DEVICE_NAME` to identify this machine.
|
|
3. Save the configuration to `~/.config/health-check`.
|
|
4. Install and enable the systemd timer.
|
|
5. 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:
|
|
> ```bash
|
|
> HEALTHCHECK_URL=https://hc-ping.com/<your-uuid> DEVICE_NAME=my-machine bash setup.sh
|
|
> ```
|
|
|
|
## Configuration
|
|
|
|
The configuration file is `~/.config/health-check`:
|
|
|
|
```
|
|
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:
|
|
|
|
```bash
|
|
./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:
|
|
|
|
```bash
|
|
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.
