Would any one know where/how this information is then used? I.e, that’s OK that it’s collecting information, but what is being done with this information? I know it isn’t being sent anywhere—so what on my installation is using this gathered information? If nothing, can I disable sysstat?
I’ve checked the sysstat website and man sysstat, but it only says what it does—not what is done with the information. Would anyone know?
Linux servers come with lots of system monitoring utilities preinstalled. However, RHEL-based servers don’t include the sysstat collection. Among others, sysstat includes sar and iostat .
nowhere, you decide what to do with that information for personal purpose, and test system performance.
I know it’s maybe useful, but the fact that I’ve never looked at the data it collects says that I won’t use it. So I’ve gone ahead and uninstalled it from my machines now
I used to use sar regularly when I was concerned with potentially overloading my system. That was while I was using a 2 core machine with no hyper-threading. Have not used it recently but probably should to monitor my continuous heavy (80+%) cpu loads even on my 6 core 12 thread system.
