are you sure this executable prints to stdout, not stderr?
does these commands give the same output (on shell):
/usr/local/netsaint/libexec/check_http 127.0.0.1 -p some_port > std_out
/usr/local/netsaint/libexec/check_http 127.0.0.1 -p some_port 2> std_err
if not, it prints to stderr and it's stderr you need to redirect STDERR
to the file.
or you can do:
system("/usr/local/netsaint/libexec/check_http 127.0.0.1 -p $port
2>&1");
