The System Requirements documents do not list Exadata as a supported platform, although Exadata uses some form of Oracle Linux. The cartridges do support Oracle Linux versions listed below.
Foglight for Infrastructure 22.214.171.124 is supported on the same platforms as Foglight Agent Manager 5.8.1 and higher.
So no testing has been done to determine if Exadata can be monitored with the IC agent. Perhaps consider checking with Oracle support on what version of Linux is used in Exadata.
