Your program was a good start. I cleaned it up and made it loop:
#!/usr/bin/perl -w
use strict;
open(LOAD, "/proc/loadavg") or die "couldn't open /proc/loadavg: $!\n";
$_ = <LOAD>;
s/^(.*?) .*/$1/;
if ( $_ > 9 ) {
print "The Enterprise, NCC-1701D, may not go faster than warp 10.\n"
# (And if a Voyager shuttle goes warp 10, you get one crappy episode.)
##`/sbin/service httpd restart`;
}
sleep 1; # NB: The kernel won't update the loadavg more than once a second
exec $0;
You can stop it from looping by pressing control-c.
I suggest that you consider turning off Apache when the load is above 9
and don't turn it back on until the load drops below 9.
