有一些进程,例如nginx会重写cmdline:
[root@vm-vm114 falcon-agent]# ps aux|grep nginx
root 14811 0.0 0.0 108964 1884 ? Ss 19:18 0:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf
nginx 14812 0.0 0.1 109388 2736 ? S 19:18 0:00 nginx: worker process
nginx 14813 0.0 0.1 109388 2656 ? S 19:18 0:00 nginx: worker process
root 15182 0.0 0.0 103336 864 pts/2 S+ 19:57 0:00 grep nginx
[root@vm-vm114 falcon-agent]#
[root@vm-vm114 falcon-agent]# xxd /proc/14811/cmdline
0000000: 6e67 696e 783a 206d 6173 7465 7220 7072 nginx: master pr
0000010: 6f63 6573 7320 2f75 7372 2f73 6269 6e2f ocess /usr/sbin/
0000020: 6e67 696e 7820 2d63 202f 6574 632f 6e67 nginx -c /etc/ng
0000030: 696e 782f 6e67 696e 782e 636f 6e66 inx/nginx.conf可以看到,原本看起来应该是0x00的地方,却用0x20(空格字符),falcon-agent在使用这个库获取到的进程含有空格,会导致cmdline无法匹配上。
