This monitor checks the Auto Create Statistics setting for this database. Since this monitor is a part of an overall standards requirement, an alert would be generated if the setting does not meet the specified standard.
The query optimizer needs up-to-date and accurate statistics in order to generate good plans. In most cases, it’s best to let SQL Server maintain the statistics. If you turn “Auto Create Stats” and “Auto Update Stats”, then it is up to you to keep the statistics up-to-date somehow. Failure to do so will lead to poor query performance. Most applications should have these options ON.
A warning alert will be raised if the option does not match the required setting. Out of the box, the monitor is configured to alert when this setting is set to “OFF”.
This issue may be resolved by:
Changing the configuration setting for this database to match the expected value.
Overriding the expected value for this unit monitor for this specific database or all databases.
Alternatively, if this monitor is not of concern for this database:
Disabling the monitor using overrides for this specific database or all databases.
Disabling the top-level aggregate configuration monitor using overrides for this specific database or all databases.
