Was ist das Dashboard?

Das Dashboard ist die interaktive Benutzeroberfläche von SOLECTRUS, die über einen Webbrowser verwendet wird.

Über den Port 3000 ist das Dashboard im Browser erreichbar. Die Adresse lautet dann beispielsweise http://raspi:3000. Der Port kann bei Bedarf geändert werden.

Das Dashboard benötigt Zugriff auf die drei Datenbanken (InfluxDB, PostgreSQL und Redis).

Logging

Das Dashboard schreibt ein Protokoll ins Docker-Log, das im Normalfall so aussieht:

Das Protokoll kann über folgenden Befehl abgerufen werden:

docker compose logs dashboard

Bei Problemen oder Fehlern wird dies ebenfalls protokolliert. Es empfiehlt sich daher unbedingt, im Zweifelsfall zuerst das Protokoll zu prüfen.
