Parameters

Most of the monitoring jobs will have parameters. This is used to adjust the monitoring job behavior and to better align it with the database instance and the preferences of the DBA.

This is an example from the “Agent jobs check” that monitors agent jobs on MS SQL Server.
This dialog lets you adjust this monitoring job on only this database instance.
The layout is a descriptive parameter name, a user-configurable value, the default value, and a question mark icon. Clicking on this icon will open a pop-up with additional information about how this parameter can be configured.

The default value will be shown in bold to indicate that the job does not use the default value for a particular setting.

Each job comes with default values for the parameters, and changes to the parameters are written in the dbw_parameters table in the database instance for engine jobs and as metadata, if changed from defaults, if its no-engine jobs.
