Alerting

Alerting services are available in the hopit Edge service and in the hopit Portal. E-Mail alerting on Data Lake level or Grafana alerting on Dashboard level is available respectively. Complex alerting queries can be added based on the data in the Edge Data Lake or based on the Data Lake in the hopit Portal.

hopit Edge Alerting

Hopit Edge Alerting can be enabled and configured in the Edge settings:

Corresponding Edge configuration and Device Twin definition to activate the Edge Alerting service:

      "SmtpPassword": "<PASSWORD>",
      "SmtpHost": "<HOST>:<Port>",
      "Recipients": [
          "office@heap-engineering.at"
      ],
      "Enabled": true
  }
}

The alerting rules are hard coded and includes:

• Service down (for all running services like VPN, Data Lake, ...)
• Windows Service down (hopit. Edge service, TwinCAT services and the VPN service)
