I had set the crontab to run reporter.

maybe my data have error or data less than 5 hours( and mysql uptime only 15 hours):

I modfity thekontroll-stats-gather-5.0.x_linux-x86-2.0.1.pl script, disable the error data to “-1″ like below,because it's unable to continue.

….

    debug_report(”## process start”);
    parse_data($xml_file,$server_id,$active_status);

$varlist{'max_binlog_cache_size'} = “-1″;
$varlist{'max_join_size'} = “-1″;
$varlist{'max_seeks_for_key'} = “-1″;
$varlist{'max_write_lock_count'} = “-1″;
$varlist{'sql_max_join_size'} = “-1″;
$varlist{'sql_select_limit'} = “-1″;

    insert_data() or error_report(”$h [fail]“);

….
