安装systemtap

#debuginfo-install kernel

安装完成后，通过下述方法确认systemtap安装完成

[root@db systemtap-2.4]# stap -ve 'probe begin{ log("hello systemtap!") exit() }'

使用

           目前个人对于Systemtap的时候主要依赖于其默认的示例文件，示例文件存放于/usr/local/share/doc/systemtap/examples/中，主要包含general、interrupt、io、locks、memory、network、process、profiling、stapgames、virtualization这些内容。
