The MODES class record contains data describing time spent in each of the processor modes. The MODES class record has a record type of 2; its size depends on the number of active CPUs on the system being monitored. The size, in bytes, is calculated by adding the size of the class header, the class prefix, and the data blocks contained in the record. This is shown in the following formula, which assumes that all CPUs are active:
13 + 8 + (33 * MNR_SYI$B_MPCPUS) |
Figure H-16 illustrates the format of the MODES class record.
