[Valgrind-users] How to run Valgrind for a child process

[Shi, Y. <Yun...@ls...>]

Hi there,

I am trying to measure a process running by spawn fast cgi. Spawn fcgi will fork a child process to run my application. Like this:

spawn-fcgi -p 9001 -a 127.0.0.1 -F 1 ./restactivator

while restactivator is my application.

How to perform dynamic analysis using Valgrind in this case? I tried several thing, none of them works.

spawn-fcgi -p 9001 -a 127.0.0.1 -F 1 "valgrind --leak-check=yes ./restactivator > memoryCheck.txt"   // spawn-fcgi: child exited with: 2
spawn-fcgi -p 9001 -a 127.0.0.1 -F 1 valgrind --leak-check=yes ./restactivator // spawn can't recognize the parameters
spawn-fcgi -p 9001 -a 127.0.0.1 -F 1 "valgrind --leak-check=yes ./restactivator" // child exit 2

spawn-fcgi -p 9001 -a 127.0.0.1 -F 1 /usr/local/bin/valgrind --leak-check=yes /root/nxtcore-yshi/nxtcore/nxtrestfwk/restactivator
// parameter not recognized

spawn-fcgi -p 9001 -a 127.0.0.1 -F 1 "/usr/local/bin/valgrind --leak-check=yes /root/nxtcore-yshi/nxtcore/nxtrestfwk/restactivator"
// exit 2

Thank you,
Yuning
