CPU分布不均

1.查看系统中断信息:

 cat /proc/interrupts

2.查看软中断信息：

cat /proc/softirqs

3.查看可用时钟源:

cat /sys/devices/system/clocksource/clocksource0/available_clocksource

4.查看当前时钟源:

cat /sys/devices/system/clocksource/clocksource0/current_clocksource

5.查看网卡支持多少队列

awk '$NF~/eth/{print $1,$NF}' /proc/interrupts  
37: eth0-TxRx-0 
38: eth0-TxRx-1 
39: eth0-TxRx-2 
40: eth0-TxRx-3 
41: eth0-TxRx-4 
42: eth0-TxRx-5 
43: eth0-TxRx-6 
44: eth0-TxRx-7 

cat /proc/irq/37/smp_affinity 
01 
cat /proc/irq/38/smp_affinity_list  
01

6.查看大业信息：

 
ps -eo pid,tty,user,comm,lstart,etime | grep khugepaged
