Logging

Log messages of the hopit Edge devices can be seen in the Edge web-interface.

If the Log Collector service is enabled, all log messages are indexed and sent to the hopit Portal.

Edge Log view on the Edge and in the Portal:

Edge-UI

The Log page shows the live hopit Edge application log. In version 1.7.0 it also merges messages from the background Updater, so package download and installation progress can be inspected in one view.

https://localhost:5050/Log

Portal-UI

The log messages can be seen in the Monitoring dashboards: hopit Portal -> Edge Devices -> Monitor.

https://<server>.hopit.at/device/Edge-97223/Monitor

Portal-UI aggregated

Aggregated log messages of all Edge devices can be seen at hopit Portal -> Monitoring.

Device Twin

The Log sections controls the log level for the Edge Device and the LogCollector enables the log synchronization to the hopit Portal.

{
  "Log": {
      "LogLevel": "Information"
  },
  "LogCollector": {
      "Enabled": true
  }
}

Updater log

Package operations run in a separate Updater process. Its messages are forwarded to the same Log page as the main application log. If the web application temporarily disconnects during an update, the Updater replays its recent history after the connection returns, allowing you to review progress and errors that occurred during the interruption.

To change the log level, open the Settings page on the Edge device or update the Device Twin and select one of the following options:

• Trace
• Debug
• Information
• Warning
• Error
• Critical
• None

The default log level is Information.
