If you need to do some reasonably complicated parsing of the returned 
page,
you could create a Perl plugin something like this:

    use LWP::Simple;
    #   ^^^--- Enables you to do HTTP GETs straight out of Perl
 
    #         (All the other 
    #        plugin boilerplate
    #             here)
 
    my $report = get($the_url_you_want);
 
    # $report now contains the whole page, do some
    # pattern matching to decide how to respond
    # This gets as sophisticated as your patterns.
 
    unless ($report) {
        print "Couldn't read report page";
        exit $ERRORS{'UNKNOWN'};
    }
    if ( $report =~ /bad bad bad/ ) {
        print "db2 is bad bad bad!";
        exit $ERRORS{'CRITICAL'};
    }
    if ( $report =~ /not so good/ ) {
        print "db2 is not so good";
        exit $ERRORS{'WARNING'};
    }
    if ( $report =~ /happy happy/ ) {
        print "db2 is happy happy!";
        exit $ERRORS{'OK'};
    }
 
    # We get here if we got data but no patterns matched
    print "Couldn't understand the report page";
    exit $ERRORS{'UNKNOWN'};

Anyway, you get the idea.

Cheers,
Roger
