第 4 章 show bgp 至 show cpu 命令
show cpu
Current control point elapsed versus the maximum control point elapsed for:
5 seconds = 99.0%; 1 minute: 99.8%; 5 minutes: 95.9%
CPU utilization of external processes for:
5 seconds = 0.2%; 1 minute: 0.0%; 5 minutes: 0.0%
Total CPU utilization for:
5 seconds = 0.2%; 1 minute: 3.3%; 5 minutes: 2.5%
注
“
Current control point elapsed versus the maximum control point elapsed for” 语句意味着在定义的时
间段内将当前控制点负载与看到的最大负载进行比较。这是一个比率而非绝对数。数字
99% 与 5
秒间隔对应意味着当前控制点负载为在此
5 秒间隔内可见的最大负载的 99%。如果负载一直继续
增加，则它会始终保持在
100%。但是，由于尚未定义最大绝对值，实际 CPU 可能仍然具有许多
可用容量。
以下示例展示如何显示多个模式下的系统情景的
CPU 利用率：
ciscoasa# show cpu context system
CPU utilization for 5 seconds = 9.1%; 1 minute: 9.2%; 5 minutes: 9.1%
以下示例展示如何显示所有情景的
CPU 利用率：
ciscoasa# show cpu usage context all
5 sec 1 min 5 min Context Name
9.1% 9.2% 9.1% system
0.0% 0.0% 0.0% admin
5.0% 5.0% 5.0% one
4.2% 4.3% 4.2% two
以下示例展示如何显示名为 “
one” 的情景的 CPU 利用率：
ciscoasa/one# show cpu usage
CPU utilization for 5 seconds = 5.0%; 1 minute: 5.0%; 5 minutes: 5.0%
以下示例激活分析器并指示其存储
1000 份采样。
ciscoasa# cpu profile activate
Activated CPU profiling for 1000 samples.
Use "show cpu profile" to display the progress or "show cpu profile dump" to interrupt
profiling and display the incomplete results.
以下示例展示分析的状态（正在进行中和已完成）：
ciscoasa# show cpu profile
CPU profiling started: 13:45:10.400 PST Fri Nov 16 2012
CPU profiling currently in progress:
Core 0: 209 out of 1000 samples collected.
Use "show cpu profile dump" to see the results after it is complete or to interrupt
profiling and display the incomplete results.
ciscoasa# show cpu profile dump
