Configuring Heartbeat
After installing, you will need to configure Heartbeat to start monitoring specific services or endpoints. Let’s walk through the configuration process:

heartbeat.monitors:
- type: http
name: MyWebApp
schedule: '@every 60s'
urls: ['https://mywebapp.example.com']
check.response:
status: 200
# Save and exit
In the configuration above, Heartbeat is set to check the specified URL every 60 seconds and expect a 200 HTTP status response.
Test the Configuration
Verify your configuration by ensuring that Heartbeat successfully pings your service:

sudo journalctl -u heartbeat.service. - Firewall Settings: Ensure your firewall allows outbound HTTP/S requests from the server.

heartbeat.ymlfor syntax errors.
