How to monitor database server status in Navicat?

The methods to monitor the status of the database server using Navicat include: 1. View connection status and basic information, and detect the server's online status through the object tree and "Ping Server"; 2. Use the "Server Monitoring" panel to view performance indicators such as QPS, cache hit rate, slow query logs in real time; 3. Set up custom monitoring alarms, and warn of abnormalities through email notifications, etc.; 4. Check the slow query log regularly to optimize SQL performance. These functions help users fully grasp the database operation status and deal with potential problems in a timely manner.

Monitoring the status of the database server is an important part of ensuring the stable operation of the application. As a powerful database management tool, Navicat provides multiple ways to help users understand the operation of the database server in real time. Here are some practical methods and steps.

View connection status and basic information

In Navicat, after connecting to the database, the object tree on the left displays the status information of the current connection. Click on a connection, and the basic information of the database will usually be displayed on the right, such as version, runtime, current user, etc.

You can also quickly detect whether the database server is online through the "Ping Server" function in the "Tools" menu. This operation is similar to the ping command on the command line, which can be used to determine whether the network is smooth.

In addition, Navicat's "Server Monitoring" function (some versions support) can display system resource information such as CPU, memory, disk usage, etc., which is suitable for scenarios where comprehensive judgment of server health status is required.

Use the built-in server monitoring panel

Navicat provides a visual "Server Monitoring" panel that can display various performance metrics of the database in real time. The entry method is usually:

• Open the corresponding database connection
• Click Tools > Server Monitoring in the top menu bar

In this panel, you can see:

• Current active connections
• Query the number per second (QPS)
• Cache hit rate
• Slow query log statistics
• InnoDB buffer pool usage, etc.

These data are very helpful in judging database load and whether there are performance bottlenecks. If you find that QPS suddenly soars or cache hit rate drops significantly, you may need to further troubleshoot the problem.

Set up custom monitoring alarms (advanced features)

Navicat Premium or Enterprise also supports setting custom monitoring rules and sending alarm notifications in case of exceptions. The configuration method is roughly as follows:

1. Go to Tools > Monitor
2. Create a new monitoring task
3. Set trigger conditions, such as the number of connections exceeds a certain threshold, the number of slow queries is too high, etc.
4. Configure notification methods, such as email reminders

This function is especially suitable for operation and maintenance personnel. It can receive early warnings before problems occur and deal with potential risks in a timely manner.

It should be noted that the functions of Navicat in different versions are slightly different. It is recommended to check the official documentation to confirm whether relevant functions are supported.

Regularly check slow query logs

Although this is not the traditional "server state", slow query logs are an important basis for judging database performance. In Navicat, you can view it in the following ways:

• Open the corresponding connection
• Go to Tools > Slow Query Log Analysis

Here you can see the recently executed slow query statements to help you locate inefficient SQL and optimize database performance.

Basically these are the methods. The functions provided by Navicat can already meet the daily monitoring needs of most users. The key is to select the appropriate tools and metrics based on the actual scenario.
