Memory Utilization
previous next
SarCheck identifies a shortage of memory in several different ways to make sure that you won't buy additional memory unless you really need it. In this case, SarCheck analyzed the CPU utilization of processes whose activity is associated with memory pressure.

 

At least one indication of a memory shortage was seen in the following statistics: Data collected with ps -elf shows that the sched daemon used 4 seconds of CPU time. This indicates a possible memory shortage. Data collected with ps -elf shows that the vhand daemon used 4 seconds of CPU time. This indicates a possible memory shortage, which is confirmed by other statistics related to memory utilization. The swap out rate peaked at 1.04 per second from 10:45:00 to 10:50:01. Peak resource utilization statistics can be used to help understand performance problems. If performance was worst during the period of peak swap out activity, then a performance bottleneck may be a memory shortage.
