line notify for cacti 1.x 20200921更新版

1. vim thold_functions.php 找到「function thold_mail」這個 Function，在最後的「return '';」上方加入以下程式碼：
2.把 your_line_token 改成自己使用的 token
/* LINE訊息告警 */

thold_debug("LINE alert-----------------");

$ttime=date("Y/m/d h:i:sa");

$content = trim("$subject")."\n"."\n".$ttime;

if ($data != '') {

    foreach ($data as $val) {

        $ffile = fopen("/tmp/qq.png","w+");

        fwrite($ffile,$val);

        fclose($ffile);

        $linefields = array('message' => $content,

                            'imageFile' => curl_file_create('/tmp/qq.png'));

        line_notify($linefields);

        unlink('/tmp/qq.png');

    }

}else{

    $linefields = array('message' => $content);

    line_notify($linefields);

}

thold_debug("LINE alert-----------------");

/* LINE訊息告警 */

3.一樣在「function thold_mail」這個 Function裡面找到
$attachments[] = array(
    'attachment' => rrdtool_function_graph($val['local_graph_id'], '', $graph_data_array, ''),
    'filename' => 'graph_' . $val['local_graph_id'] . '.png',
    'mime_type' => 'image/png',
    'local_graph_id' => $val['local_graph_id'],
    'local_data_id' => $val['local_data_id'],
    'inline' => 'inline'
);
下面一行加上
/* LINE訊息告警 */
$data1 = @rrdtool_function_graph($val['local_graph_id'], '', $graph_data_array);
array_push($data, $data1);
/* LINE訊息告警 */


4.在function thold_mail」這個 Function，在最後的「return '';」下方加入以下程式碼

/* LINE訊息告警 */

function line_notify($linefields){

    $ch = curl_init();

    $lineurl="https://notify-api.line.me/api/notify" ;

    $linehead=array("Content-Type: multipart/form-data",

                        "Authorization: Bearer your_line_token");

    curl_setopt($ch, CURLOPT_URL, $lineurl);

    curl_setopt($ch, CURLOPT_HEADER, true);

    curl_setopt($ch, CURLOPT_HTTPHEADER, $linehead);

    curl_setopt($ch, CURLOPT_NOBODY, false);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    curl_setopt($ch, CURLOPT_POST, true);

    curl_setopt($ch, CURLOPT_POSTFIELDS, $linefields);

    curl_exec($ch);

    curl_close($ch);

}

/* LINE訊息告警 */
