The Job output of the Support Diagnostics often contained ERROR lines, that actually didn't indicate errors. With this werk, these lines are now WARNING and INFO messages.

For example, on RedHat based systems, the Dpkg packages information reported "ERROR - No information" because the dpkg command is missing there. This will produce an "INFO - No data", now.

Also, when creating the "Performance graphs of Checkmk Server", and the Checkmk server itself was not a monitored host, the error "ERROR - No Checkmk server found" was shown. This will be shown as "WARNING - No Checkmk server found", now.
