The services ORA <SID> Performance IO Stats Bytes and ORA <SID> Performance IO Stats Requests crashed with TypeError: unsupported operand type(s) for -: 'NoneType' and 'int' if the Oracle agent plug-in reported a file I/O statistics counter that is not an integer.

The affected counter is now reported as UNKNOWN, for example Temp File Large Write: Oracle reported no integer value, counter skipped, and the other counters are monitored as before.
