Comparison of database monitoring and management of MySQL and TiDB

Comparison of database monitoring and management between MySQL and TiDB

Introduction:
With the advent of the big data era, efficient management and monitoring of databases has become an indispensable need for enterprises and individuals. In the two databases of MySQL and TiDB, we compare and discuss their database monitoring and management respectively, hoping to bring some valuable information and enlightenment to readers.

1. MySQL database monitoring and management
MySQL is a commonly used relational database management system and is widely used in the Internet industry. Below we will introduce the main methods and tools for MySQL database monitoring and management, including command line tools and graphical interface tools.

1.1 Command line tools
MySQL provides a series of command line tools for monitoring and managing databases. The most commonly used are the mysqladmin and mysqlshow commands.

The mysqladmin command can perform some common database management operations, such as creating databases, deleting databases, viewing database status, etc. The following is a simple example:

$ mysqladmin -u root -p create mydb
Enter password: *****
Database created

The mysqlshow command is used to display database information, including database list and table list. The following is an example:

$ mysqlshow -u root -p
Enter password: *****
+--------------------+
|     Databases      |
+--------------------+
| information_schema |
| mydb               |
| mysql              |
| performance_schema |
| sys                |
+--------------------+

1.2 Graphical interface tools
In addition, MySQL also has some graphical interface tools, such as phpMyAdmin and MySQL Workbench, which can provide a more intuitive and convenient database management interface. .

phpMyAdmin is a web-based database management tool that can access the database through a browser and perform various operations. The following is an example of the interface of phpMyAdmin:

MySQL Workbench is a cross-platform database management tool that provides rich functions such as database design, query, backup and Recovery etc. The following is an example of the MySQL Workbench interface:

2. TiDB database monitoring and management
TiDB is a distributed database system that has both Advantages of traditional relational databases and NoSQL databases. Below we will introduce the main methods and tools for TiDB database monitoring and management, including Prometheus and Grafana.

2.1 Prometheus
Prometheus is an open source monitoring and alerting tool dedicated to distributed systems. TiDB integrates Prometheus, through which the status of the database can be monitored in real time. The following is an example of a Prometheus configuration file:

global:
  scrape_interval:     15s
  evaluation_interval: 15s

scrape_configs:
  - job_name: 'tidb'
    static_configs:
    - targets: ['192.168.0.1:9090']

2.2 Grafana
Grafana is an open source visual monitoring and analysis tool that is widely used in database monitoring. TiDB integrates Grafana, through which the data collected by Prometheus can be displayed and analyzed. The following is an example of a Grafana dashboard:

Conclusion:
By comparing the database monitoring and management of MySQL and TiDB, we can see The two differ in terms of functionality and tools. MySQL focuses more on command line tools and graphical interface tools, and its operations are relatively simple and intuitive; while TiDB integrates advanced monitoring and management tools such as Prometheus and Grafana, making it easier to conduct real-time monitoring and data analysis.

In summary, choosing MySQL or TiDB needs to be decided based on actual needs and environment. If you have higher requirements for real-time monitoring and analysis of the database, then TiDB may be a better choice; if you are more concerned about database management operations, then MySQL may be more suitable.
