To view the server running time, it can be achieved through Navicat's "Server Monitoring" function or performing SQL queries. 1. After connecting to the database in Navicat, right-click to connect → "Monitoring" → "Server Monitoring" and view the "Uptime" field in the "System Information" area; 2. For MySQL, you can execute SHOW GLOBAL STATUS LIKE 'Uptime' in the query window; or use the format statement SELECT VARIABLE_VALUE AS UptimeSeconds, TIME_FORMAT(SEC_TO_TIME(VARIABLE_VALUE), '%Hh %im %ss') AS UptimeFormatted FROM performance_schema.session_status WHERE VARIABLE_NAME = 'Uptime'; Get the run time; 3. Note that there may be differences in the time obtained in different ways. It is recommended to save common queries and adjust commands according to the database type. For example, PostgreSQL uses the pg_postmaster_start_time() function, and ensure that it has corresponding permissions.

Want to know how to use Navicat to view server running time? In fact, the method is quite straightforward. As long as you are a little familiar with the software interface and related functions, you can do it.

1. Use the Server Monitoring feature to view the runtime

Navicat (especially Navicat Premium or the corresponding database version) has built-in "Server Monitoring" tools, allowing you to quickly view multiple metrics including server running time.

The operation steps are as follows:

• Open Navicat and connect to your database server
• Right-click on the target connection in the left connection list → "Monitoring" → "Server Monitoring"
• After entering the monitoring interface, find the "System Information" or "Status Summary" area on the top or sidebar.
• The "Uptime" or "Runtime" field will be displayed, usually in the form of days, hours, and minutes.

This function not only shows the running time, but also monitors key data such as CPU, memory, connections, etc. in real time.

2. View MySQL runtime through SQL query

If you are using a MySQL database, you can also directly execute SQL commands to get the server running time.

Open the query window in Navicat and enter the following statement:

 SHOW GLOBAL STATUS LIKE 'Uptime';

After execution, you will see a line of results, which shows the number of seconds passed since the server started. You can convert the number of days yourself or let Navicat handle it automatically.

If you want to be more intuitive, you can use the following statement:

 SELECT 
    VARIABLE_VALUE AS UptimeSeconds,
    TIME_FORMAT(SEC_TO_TIME(VARIABLE_VALUE), '%Hh %im %ss') AS UptimeFormatted
FROM 
    performance_schema.session_status
WHERE 
    VARIABLE_NAME = 'Uptime';

The result returned in this way will be automatically converted to the format of hours, minutes, and seconds, which will look clearer.

3. Precautions and tips

Some users may find that the "running time" found in different ways is slightly different, which is usually caused by the monitoring tool's value timing or cache mechanism, which is a normal phenomenon.

• If you often need to check the run time, you can save the common queries and run them directly next time
• Some database types (such as PostgreSQL) may require different SQL commands, such as using pg_postmaster_start_time() function
• Make sure you have permission to access system status or performance mode or you may encounter permission errors

Basically all this is it, the operation is not complicated but details are easy to ignore, especially the differences between different databases.
