I have seen a question in stackoverflow, and tried the DTrace script in my host
(Solaris 10):
#!/usr/sbin/dtrace -s
#pragma D option quiet
dtrace:::BEGIN
{
printf("%-20s %-12s %s\n", "TIME", "LATENCY(ms)", "HOST");
}
pid$target::getaddrinfo:entry
{
self->host = copyinstr(arg0);
self->start = timestamp;
}
pid$target::getaddrinfo:return
/self->start/
{
printf("%d", arg1);
this->delta = (timestamp - self->start) / 1000000;
printf("%-20Y %-12d %s\n", walltimestamp, this->delta,
self->host);
self->host = 0;
self->start = 0;
}
the output of arg1 isn't like 0 (success) nor error (fail), but likes a
pointer. Per my understanding, the arg1 should be the return value.
Could anyone help on this issue? Thanks very much in advance!
Best Regards
Nan Xiao
