sysdig是透過kernel driver達到監控資源的方式，因此，在使用sysdig前，必須要編譯安裝sysdig的driver(scap.ko)，步驟如下：
$ cd
$ git clone https://github.com/draios/sysdig
$ mkdir sysdig/build
$ cd sysdig/build
$ cmake ..
$ make -j4
$ sudo make install
$ sudo insmod ./driver/scap.ko
$ sudo sysdig

sysdig輸出的格式如下：
%evt.num %evt.outputtime %evt.cpu %proc.name (%thread.tid) %evt.dir %evt.type %evt.info
可以透過過濾條件讓sysdig輸出感興趣的事件，如下：
$ sudo sysdig fd.name contains /etc
