The CPUs / CPU Summary screen provides high level detail on the activity of each processor in the System.
Busy % breaks down the total CPU busy value into Idle, Interrupts, and Overhead. Idle is the percent of time the processor did nothing. Interrupts is the percent of time the processor serviced low-level disruptions to normal processing such as an I/O completion. Overhead is the percent of time the processor spent creating or deleting processes.
Create and Delete show the number of processes new to the system and removed from the system as seen by MOMI. This gives an indication as to the level of process turnover on the System. Typical Guardian-based processes usually start and stay started. A high process turnover may indicate a problem. OSS-type processes usually have a much higher turnover due to the nature of the UNIX-like environment.
Free CIDs are a MEASURE resource used to contain counters for measurements. Enough Free CIDs should be available to support current and additional measurements.
CPU Queues are reported as Instant, or what is in the queue right now, and Average, which is the queue over the Interval period. The Instant queue is a whole number of processes while the Average is a decimal value. The Average memory queue is only available (i.e. have a non-zero value) on older platforms.
I/Os / Second indicate the gross total disk I/O activity at the CPU level. The physical I/Os plus the I/Os satisfied from cache equal the total I/Os. The percent of cache hits indicates the overall effectiveness of the disk cache. High levels of I/Os with a low cache hit percentage may indicate insufficient cache allocated to disk.
