Hey Daniel,
If it is not explicitly listed in the Compatibility Matrix or Platform Support Matrix, it is not currently supported.
Support doesn't have roadmap information but someone from your account management team could look into this for you.
Reach out to your account manager to get that conversation started.
While it has not been tested, but I'd think you could work with some of the oracle- or solaris-capable probes (review the platform support matrix to see what probes work on which platforms).
While the architecture may be different on an Exalogic machine, some of the same metrics might be available.
