What about sysstat that provides sar (and iostat). I have this logging every minute in some environments and I can look back and find the root cause of performance issues over multiple devices and networks. kSar can graph this quickly.
vmstat is essential in it's own way, the run queue is critical in threaded environments like weblogic with osb/soa where a default install on a 2 vCPU instance won't perform.
Also; dtrace for linux and osx.
- mprovost 13y agoIf you're still using sar have a look at atop instead. It's great, it's like top crossed with Time Machine, you can log your system's performance like sar but then look at it like top and rewind until you find the performance problem.
