| Name: | External fragmentation (all databases) |
| Platform: | Sqlserver |
| Category: | Maintenance |
| Description: | External (logical) fragmentation occurs when an index leaf page is not in logical order. It occurs when the logical ordering of the index does not match the physical ordering of the index. This causes SQL Server to perform extra work to return ordered results. |
| Long description: | Collects external fragmentation statistics for tables and indexes. The information is extracted from the dynamic management function (view) sys.dm_db_index_physical_stats. |
| Version: | 1.5 |
| Default schedule: | 20 6 6 * |
| Requires engine install: | Yes |
| Compatibility tag: | [CDATA[.[type=‘instance’ & databasetype=‘sqlserver’]/instance[maj_version > ‘2000’ & hasengine=‘YES’ & eng_inst_priv = 0 & (engine_edition = ‘Microsoft SQL Server’ | engine_edition = ‘Azure SQL Managed Instance’) |
