I am new to Eclipse Hono. I have installed eclipse hono, using Helm chart and kubernetes(https://www.eclipse.org/hono/docs/getting-started), it is up and running and I am sending the messages from MQTT with AMQP Network. Here are my some doubts and questions.
- Where all the messages are get storing, and how to get access and see the data.
- How to change the Hono's database to postgresql
- Where are the Eclipse Hono files are stored.
Where all the massages are get storing, and how to get access and see the data.
The messages are not stored by the Hono. Hono just forwards the messages from the device to the back end application. In order to get the message send by the device you have to connect to the AMQP (Kafka) network. For test purposes there is Hono command line client that acts as application. It could be downloaded from https://www.eclipse.org/hono/downloads
How to change the Hono's database to postgresql
You could check the configuration at https://www.eclipse.org/hono/docs/admin-guide/jdbc-device-registry-config/. The helm chart has properties to configure external jdbc database. Basically you need deviceRegistryExample.type=jdbc and check the values for hono.jdbcBasedDeviceRegistry at https://github.com/eclipse/packages/blob/master/charts/hono/values.yaml. The PotgresSQL itself has to be deployed externally.
Where are the Eclipse Hono files are stored.
The source code is located at https://github.com/eclipse-hono/hono. Is that what you are you looking for?
