Re: [cobalt-users] CPU Heavily Loaded

> Does anyone have a script like this handy?

hi i had the same problem and am running the below script (cant remember where
i got it)
it logs to a file in the same directory called 'loadstat'
seems to work a treat then i check the ip address against my access file as

cat /var/log/httpd/access | grep 1111.1111.1111 > highiplog

this extracts the ip 1111.111.1111.111 to a file called highiplog

sort of messy but has allowed me to find the cgi that are high load

my top line
`top -n 2 >>topout`;

isent working will have a look not perfect yes a shell script that grabbed the
processes with a high load would be better but this did the trick for me.b w

 #!/usr/bin/perl
# check lode above 1 say
my $load = 1;
my $trace = "/bin/netstat -natu | grep -E \"(ESTABLISHED|TIME_WAIT|CLOSE_WAIT)\"";
my $log = "loadstat"; while(1) {
    $_ = `cat /proc/loadavg`;
    /(\d+)\.(\d\d)\s.*/;
    if($1 >= $load) {

## do top stuff
`top -n 2 >>topout`;

        open(FH, ">>$log") || die "Cannot open log file $log: $!\n";
        my $time = localtime();
        my $info = `$trace`;
        print FH $time, " load $1.$2\n", $info;
        close(FH);
    }
    sleep(60);
}
