Code samples for use with Azure SQL Database Managed Instance

Managed Instance code samples

This is a repository of code samples to use with Azure SQL Database Managed Instance (MI).

1. sp_readmierrorlog.sql is a stored procedure that provides a filtered and more readable version of the MI error log.
2. perf-counters-mi.sql is a script that collects performance counters on MI.
3. MIGP_storage_perf_limits.sql is a script that examines IOPS/throughput per database file over a period of time on MI General Purpose, and compares them against Azure Premium Storage limits. The script helps in determining if using larger files/blobs with higher limits would be beneficial for improving workload performance.
4. mi_server_resource_stats.sql is a script that creates a view named dbo.server_resource_stats. This view provides real-time resource stats for an MI instance, as a workaround for commonly observed data latency in the sys.server_resource_stats view.
5. real_time_resource_stats.sql is a query that returns real-time resource stats for an instance. It is an alternative to sys.server_resource_stats, providing another workaround for commonly observed data latency when using that view.
