How to view the size and status of the business database log file of TencentDB for SQL Server?

To view the size and status of the business database log file in TencentDB for SQL Server, you can use SQL Server Management Studio (SSMS) or execute T-SQL commands directly.

Method 1: Using SSMS

1. Connect to your TencentDB for SQL Server instance via SSMS.
2. Expand the Databases node, then right-click the target database and select Properties.
3. In the Database Properties window, go to the Files page. Here, you can see the log file (with type Log) along with its size, used space, and growth settings.

Method 2: Using T-SQL Commands

Run the following query to check the log file details:

USE [YourDatabaseName];  
GO  
SELECT  
    name AS LogFileName,  
    size * 8 / 1024 AS SizeMB,  
    FILEPROPERTY(name, 'SpaceUsed') * 8 / 1024 AS UsedSpaceMB,  
    growth AS GrowthSetting,  
    physical_name AS FilePath  
FROM sys.database_files  
WHERE type_desc = 'LOG';  

This query returns the log file name, size (in MB), used space, growth setting, and physical file path.

TencentDB for SQL Server-Specific Recommendations

For managed database monitoring, Tencent Cloud provides Cloud Monitor to track log file growth and storage usage. Enable alerts to notify you when the log file approaches its size limit. Additionally, consider using TencentDB for SQL Server’s automated backup and log truncation features to manage log file size efficiently.

Example: If the log file grows too large due to long-running transactions, you can use:

BACKUP LOG [YourDatabaseName] TO DISK = 'NUL'; -- For simple recovery model (truncates log)  
-- Or perform a proper transaction log backup in full/bulk-logged recovery models.  

For production environments, ensure proper backup strategies to avoid excessive log growth.
