ganglia中的“cpu_intr”和“cpu_sintr”是什么意思

Question

我在哪里可以看到这些解释指标？

cpu_ctxt, cpu_intr, cpu_sintr, cpu_aidle, cpu_steal

Answer 1

我假设cpu_ctxt 代表/proc/stat（参见manpage）或vmstat（csfield）报告的上下文切换的数量。

另外，man top 揭示了其他指标的含义：

       us, user    : time running un-niced user processes
       sy, system  : time running kernel processes
       ni, nice    : time running niced user processes
       id, idle    : time spent in the kernel idle handler
       wa, IO-wait : time waiting for I/O completion
       hi : time spent servicing hardware interrupts
       si : time spent servicing software interrupts
       st : time stolen from this vm by the hypervisor

地点：

• cpu_intr 映射到hi
• cpu_sintr 映射到si
• cpu_adle 映射到id
• cpu_steal 映射到st
