Summary

The rule collects the Windows "Cursor unique violations/sec" performance counter for internal XTP engine cursors.

The XTP Cursors performance object contains counters related to internal XTP engine cursors. Cursors are the low-level building blocks the XTP engine uses to process Transact-SQL queries. As such, you do not typically have direct control over them.

Cursor unique violations/sec - The number of unique-constraint violations (on average), per second.

Note that this rule is enabled only for SQL editions supporting Memory-Optimized Data (64-bit Enterprise, Developer, or Evaluation edition).
