any help on how can i use strace to get valuable information?
I tried this
strace -p <pid of squid child>
It started a non-ending trace like this ...
[root@gateway102 ~]# strace -p 7934
Process 7934 attached - interrupt to quit
gettimeofday({1260262793, 691159}, NULL) = 0
gettimeofday({1260262793, 691246}, NULL) = 0
epoll_wait(6, {}, 16384, 10) = 0
gettimeofday({1260262793, 700780}, NULL) = 0
<snip repeated epoll_wait>
is this of any use? Or i need to use another swithc combination to make
it useful?
Not sure of the strace controls myself. But that trace has already been
of some use, that process was doing nothing but idling along waiting for
some network traffic to arrive.
Time to look at any other squid processes around and see if they are
doing something.
The parent process can be expected to be idling also waiting on signals,
or doing nothing at all. Any others ...
