- Availability. Displays the percentage of time the SQL Server was available (including planned down time; for more information see the Precise Administration Guide).
- Unavailability times. Displays how long the SQL Server was down. If the Precise for SQL Server Collector was down, the status will be labeled "Unknown Time.".
- Log. Provides general information regarding each period that the SQL Server was down.
Provide information on the status of SQL Server instance, over the selected time period.

Entity | Description |
---|---|
Statement | Displays information on the activity of a specific TSQL statement. A statement is always part of a batch. When an encrypted stored procedure is encountered the statement will display “Encrypted Text”.displays, "Encrypted Text." |
Batch | Displays information on the activity of a specific batch. A batch can either be a stored procedure, stored function, trigger, or an ad hoc batch. If it is a stored object, the name of the stored objects are displayed. |
Collapsed statement | Represents similar statements that differ in their parameters (literals). In a collapsed statement, the literals are replaced with parameter markers. The collapsed statement lets you analyze the overall resource consumption of similar statements. |
Collapsed batch | Similar to collapsed statement a collapsed batch represents similar batches that differ in their parameters (literals). In a collapsed batch, the literals are replaced with parameter markers. The collapsed batch lets you analyze the overall resource consumption of similar batches. |

Entity Name (such as Collapsed Statement) | Displays the name of the entity. |
Database | Identifies the database on which the collapsed statement or batch is run. |
