MySql monitoring and alarming: How to implement MySQL monitoring and alarming system

With the advent of the big data era, MySQL database, as an efficient data storage and management tool, has been widely used in various enterprises and organizations. However, due to data security and performance issues, MySQL's monitoring and alerting system has become increasingly important.

The role of MySQL’s monitoring and alarm system

MySQL’s monitoring and alarm system can detect the running status of the MySQL server in real time, including CPU load, memory usage, network traffic, disk space, and indexes Usage, query times and other aspects of the operation status, and provide timely warnings through alarms, and guide us to optimize the problem.

How to implement MySQL monitoring and alarm system

There are many ways to implement MySQL monitoring and alarm system. Below we will introduce a MySQL monitoring and alarm implementation solution based on Zabbix monitoring system.

1. Installing Zabbix

First, we need to install the Zabbix monitoring system. Zabbix is ​​an open source network monitoring software that can monitor many types of network devices and applications, including MySQL databases. Zabbix can be installed through the following code:

wget https://repo.zabbix.com/zabbix/5.2/ubuntu/pool/main/z/zabbix-release/zabbix-release_5.2-1+ubuntu18.04_all.deb

dpkg -i zabbix-release_5.2-1+ubuntu18.04_all.deb

apt update

apt install zabbix-server-mysql zabbix-frontend-php zabbix-apache-conf zabbix-agent

2. Configuring Zabbix monitoring

After the installation is complete, we need to configure Zabbix monitoring. You can configure it by following the steps below:

• Create a user with sufficient permissions on the MySQL server so that Zabbix can connect to the MySQL server and obtain monitoring data.
• Configure the MySQL template on the Zabbix server to enable it to monitor the MySQL server. You can add a MySQL server in the "Configuration -> Hosts" page, and then add a MySQL template in the "Templates" tab.
• Configure Zabbix Agent, start Zabbix Agent, and connect it to Zabbix server. This can be set in the "Administration -> Nodes -> Agents" page on the Zabbix server page. There you will find the zabbix_agentd.conf file, which contains the configuration of Zabbix Agent.

3. Configure alarm rules

When there is a problem with MySQL, we need to receive the alarm in time. We can set alarm rules on Zabbix to send alarm notifications when MySQL parameters reach preset thresholds. Alert rules can be set up by following the steps below:

• Configure triggers on the Zabbix server to trigger alerts when MySQL parameters reach specific thresholds.
• Configure the alarm media type: for example, you can send the alarm to an application such as email, SMS, or Slack.

4. Install Zabbix plug-in

Finally, we can use Zabbix plug-ins to further extend the functionality of Zabbix. For example, you can install the JMX plug-in to monitor JMX MBeans , or install the SNMP plug-in to monitor SNMP network devices.

Here, we chose Zabbix as our MySQL monitoring tool because Zabbix's monitoring function is powerful and easy to use and configure. Of course, in addition to Zabbix, there are other MySQL monitoring and alerting tools to choose from, such as Percona Monitoring and Management, Nagios, etc.

Summary:

As enterprise data continues to grow, the operation monitoring and alarm mechanism of the MySQL database is particularly important. Choosing appropriate monitoring and alerting tools can help us detect problems in time and solve them, thereby ensuring data security and system performance. The Zabbix monitoring and alarm solution introduced above is well worth a try for open source enthusiasts and technical engineers.
