Hi Community, please see my question below. What product/components do you use and which version/fix level? Cumulocity Backend: 1013.0.260 UI: 1011.0.12 Are you using a free trial or a product with a customer license? License What are trying to achieve? Please describe in detail. I have a prob…

Hi Manfred, first of all I would basically mount the log directory to the host system, that way you can access the logs and the container itself does not get that big. -v PATH_OF_HOST:PATH_OF_CONTAINER_LOGS However the logging.xml seemed to be configured properly, although it does not delete the f…

Docker limits the size of a containers via “default docker storage” on docker/var/lib/ Link 1 Link 2 You can increase that, however I did not check about why docker sets that limit. This might have side effects.

Hi Murat, thank you for the answer. Yes, we still use thin-edge.io , so we can’t use another OPC-UA Agent. We will try to use our customized logging.xml and hopefully we can have a workaround with this. BR Manfred
