What are the key advantages of using the SQL Monitor (transaction SQLM)?

The SQL Monitor (transaction SQLM) offers significant advantages, particularly in the context of active monitoring in production environments without imposing performance overhead. This capability is crucial for organizations that require real-time insights into their SQL statement performance without negatively impacting system resources or user transactions.

By enabling active monitoring, SQL Monitor allows developers and administrators to identify slow or inefficient SQL statements as they occur. This operational visibility facilitates proactive performance management and optimizations. Essentially, it provides the ability to collect detailed monitoring data while ensuring that routine production activities remain unaffected, allowing the system to operate smoothly.

In contrast, other options would not offer the same level of advantage in terms of resource management or real-time monitoring context. For instance, while synchronous collection of monitoring data can be useful, it may implement a level of overhead that could affect performance. Similarly, scheduling ABAP programs or displaying execution plans serves different purposes and does not directly relate to the benefits of the active monitoring nature of SQL Monitor in a live production environment.
