[mk_oracle] Flex ASM redundancy configuration

I want to monitor a Flex ASM instance. When I do so, I get an error message regarding Flex redundancy (please ignore the metric about usage):

However, I can’t find the requirements for this check anywhere, or how I might adjust the corresponding metric. The check has no available configuration options regarding redundancy.

How can I configure this check, or what kind of configuration is expected?

Thanks and best regards
Marcel
