Windows has a Performance Counters infrastructure. The OS provides some common counters, and I can go add my own. What is the corresponding concept in Linux/Unix?
回答1:
Take a look at:
- OProfile
- perfctr
- perfmon2
回答2:
There is also PAPI and PerfSuite.
回答3:
Several applications exist which periodically check system performance.
- iostat, vmstat, and netstat - Run these commands once to get a snapshot of activity.
- sysstat - This runs periodically and maintains a history of statistics such as the above.
- Munin - As sysstat, but with pretty web graphs.
