Retrieves memory pressure notifications and utilization metrics from SQL Server resource monitor ring buffers.
Analyzes SQL Server's internal resource monitor ring buffers to identify memory pressure events and track memory utilization over time. This helps DBAs diagnose performance issues caused by insufficient memory, excessive paging, or memory pressure conditions that trigger automatic memory adjustments.
The function returns detailed memory statistics including physical memory usage, page file utilization, virtual address space consumption, and SQL Server-specific memory allocation metrics. Each record includes the exact timestamp when memory conditions were recorded, making it valuable for correlating memory pressure with performance degradation during specific time periods.
This command is based on a query provided by Microsoft support and queries the sys.dm_os_ring_buffers DMV to extract resource monitor notifications.

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
