10 Nov/15 - Trick: Get More Accurate Memory Statistics By Zone On Solaris

TeamQuest CMIS (Agent Technology) offers the capability to collect Zone related data like %cpu, lioch, rss etc... The “rss” parameter represent the resident set size (real memory) in kilobytes of all running processes at the end of the interval. If a process ends within the sampling interval.

When looking at this parameter on servers that run Oracle databases we see that this value can become very large due to the fact that shared memory segments are counted several times. We wrote a small User Table Agent that will provide you with more accurate memory related statistics by using the command "prstat" on Solaris 5.10 and "zonestat" on Solaris 5.11, feel free to download the  white paper & bits here.
