ngx-active-reqs error

yekeqiang

我的环境：

CentOS 5.8

elfutils-0.149

systemtap-2.6

运行这个的时候发生如下错误

sudo ./ngx-active-reqs -p 5965

ERROR: MAXACTION exceeded near keyword at <input>:32:13

Tracing 5965 (/apps/svr/nginx-lua/sbin/nginx)...

WARNING: Number of errors: 1, skipped probes: 0

WARNING: /opt/stap/bin/staprun exited with status: 1

Pass 5: run failed. [man error::pass5]

运行下面这个没有问题：

sudo ./ngx-req-distr -c -m `cat /apps/logs/nginx/nginx.pid`

所以运行第一个命令出现错误是什么原因？

这个错误是指脚本超出了 systemtap 自身的 MAXACTION 这个保护限制，所是只是一个小问题而已。解决办法是自己调大这个上限，比如

    sudo ./ngx-active-reqs -p 5965 -a 'MAXACTION=200000'
