AW: check_http question?

[Helmut Januschka]

I did such a plugin:

you also need a perl script within you plugins dir, returns downloaded bytes and time in seconds how long it took
just run check_site.sh -h , and enyjoy :)
:
image_leecher.pl:
#!/usr/bin/perl
use HTTP::Request;
use LWP::UserAgent;
use POSIX;

$BYTES=0;
while(<>) {
        $BYTES += length($_);

                        if($_ =~ /^.*"(.*?).gif".*$/) {
                                downloadPic($1 . ".gif");
                        }

                        if($_ =~ /^.*'(.*?).gif'.*$/) {
                                downloadPic($1 . ".gif");
                        }


                        if($_ =~ /^.*"(.*?).jpg".*$/) {
                                downloadPic($1 . ".gif");
                        }

                        if($_ =~ /^.*'(.*?).jpg'.*$/) {
                                downloadPic($1 . ".gif");
                        }


}
sub downloadPic {
        $myPic = shift;
        if($myPic !~ /^http:.*$/) {
                $myPic = "http://wcm.krone.at" . $myPic;
        }
        if($GOT_P{$myPic} != 1) {
                $ua = LWP::UserAgent->new(agent => 'Nagios Plugin Browser :)');
                $request = HTTP::Request->new(GET => $myPic);
                $response = $ua->request($request);
                $BYTES += length($response->content);

        }
        $GOT_P{$myPic}=1;
}
print ceil($BYTES/1024);

Trying /usr/lib/nagios/plugins/check_http -h

It'll show these options:
-w, --warning=INTEGER
Response time to result in warning status (seconds)
-c, --critical=INTEGER
Response time to result in critical status (seconds)

This allows you to use check_http to send warnings or critical messages 
based upon response time. It won't give you anything that you can use 
for reporting though.
