Event Monitors Wizard (DB2 LUW)
Go Up to IBM DB2 for Linux, Unix, and Windows Object Wizards
An event monitor is used to collect information about a particular database and connected appliances when one or more events you specify take(s) place. Where a snapshot monitor captures information for a given moment in time, the event monitor lets you trace the activity you specify.
The Event Monitor Wizard lets you provide basic properties, select event types, and specify conditions where appropriate, for an event monitor.
To create a new event monitor using a wizard:
- Open a creation wizard for an event monitor. For details, see Opening an Object Wizard.
- Use the following topics as a guide to setting properties and performing tasks as you pass through the wizard panels:
- Properties panel - for details, see Event Monitors (DB2 LUW) - Properties.
- Definition panel - for details, see Event Monitors (DB2 LUW) - Definition.
- Conditions panel - for details, see Event Monitors (DB2 LUW) - Conditions.
- DDL View panel - for details, see Previewing the DDL Generated to Create the New Object.
- Finally, use the Execute button to create the object.
