Might the theory be if R783IIPB is large relative to R893IIFS, maybe you have an issue?
According to this: https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.1.0/com.ibm.zos.v2r1.erbb200/erbb200209.htm RMF calculates "Percent I/O processor busy" as (IIPB * 100) / (IIPB + IIPI) Which would make sense if those are samples of some type. Looking across a several customers, I do see that they tend to be about 240 samples per second, within about +/- 1%. So it does seem like they're samples of some type. I see very few intervals with an I/O processor more than 10% busy in the customers I sampled though, which matches my historical understanding that most customers don't have an issue with SAP capacity.
