Changing the Log Level of a Docker Container

In the administration application you have the possibility to change the log level for a Docker container. The functionality is currently available for the following service types:

• pas-nestjs = PAS services based on NestJS

• pas-service = PAS applications without UI

You have two options to open the input form where you can change the log level:

• Use action Change log level from the quick actions bar in the services' list. This will open a pop-up window.

• Open the details page of the service and scroll down to section Logs:

Changing the log level varies for the different service types. The details are explained below.

• Container logs: Log files inside all containers are deleted after 7 days.

• Log Analyzer (OpenSearch) logs:
