Cacti is a graphical analysis tool for network traffic monitoring based on PHP, MySQL, SNMP and RRD Tool. Cacti provides a quick poller, advanced chart templates, multiple data collection methods, and user management features. All of this is packaged in an intuitive, easy-to-use interface that makes sense for local area network and complex networks of thousands of devices.

However, in order not to miss important threshold alerts, email notifications are often insufficient, and telephone notifications are often the most direct way. When an important alarm is generated, the alarm call can be received at the first time, so that the user can handle it at the first time. Cloud Alert, the intelligent alert platform of Ruixiang Cloud, can realize telephone alert simply and quickly. Next, let's talk about how to realize it!

There are three main steps:

1. Integrated application-that is, integrating Cacti into Ruixiang Cloud intelligent alarm platform

2. Set Dispatch Policy-Sets who notifies when an alarm occurs

3. Set Notification Policy-Set how your phone is notified

I. integrated application

1. Go to www.aiops.com and log in

2 . Create a Cacti app in Cloud Alert, click Integration-Monitoring Tools- Cacti

3. Fill in "App name" and click "Save and get app key"

4. Install and configure thold plug-ins, configure email alerts

5. Modify thold plugin to support CloudAlert access

(1)Open {cacti_home}/plugins/thold/thold_functions.php For example:

vim /var/www/html/cacti/plugins/thold/thold_functions.php

Go to function thold_mail:

/* Sends a group of graphs to a user */

function thold_mail($to, $from, $subject, $message, $filename, $headers = '') {

global $config;

thold_debug('Preparing to send email');

include_once($config['base_path'] . '/plugins/settings/include/mailer.php');

include_once($config['base_path'] . '/plugins/thold/setup.php');

$subject = trim($subject);

$message = str_replace('', $subject, $message);

...... //omitted here

}

After $message = str_replace ('', $subject, $message) ; add the following code and replace the appkey parameter:

function onealert_for_cacti($msg, $subject) {

$fields = array(

"app" => "--", fill in the appkey generated when you create an app

"subject" => $subject,

"msg" => $msg

);

$fieldsdate = json_encode($fields);

$ch = curl_init("http://api.aiops.com/alert/api/event/cacti/new");

curl_setopt($ch, CURLOPT_HEADER, "Content-type: application/json");

curl_setopt($ch, CURLOPT_POST, 1);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_POSTFIELDS, $fieldsdate);

$output = curl_exec($ch);

if(curl_errno($ch)){

print curl_error($ch);

}

curl_close($ch);

echo $output;

}

onealert_for_cacti($message,$subject);

(2)Restart SNMP

service snmpd restart

(3)Restart httpd

service httpd restart

(4)Configure Cacti to trigger alerts and check Cloud Alert and Mail Alerts

II. Set dispatch policy

1. Click Configure-Assignment Policy-New Assignment

2. Enter the name of the dispatch policy-select Apply-set the dispatcher (the person to notify when an alarm occurs), and click Save
