> # Viewing Event Tracing Information

> You can view all events of a service or filter the events to view. You can also use the Find function to search for a specific event in the events that are displayed in the Details pane.

> NOTE: When the service event trace is refreshed, it is possible that the displayed information may no longer be available in the event trace file because the event trace file is circular, meaning that the oldest events are overwritten with the newest events. If this happens, the SequeLink Manager displays `Information not available`.``

> See "Event Handling" for general information about event handling.

> To view event trace information:

> 1. Click the Service Event Trace node of a service. The Details pane displays a list of all events, which depends on how event tracing is configured.

> 2. Optionally, you can search for a specific event in the Details pane. To do this, right-click the Service Event Trace node of a service; then, select Find Event. The Find Event window appears.

> In this window, perform the following actions:

> 1. Select the type of event you want to view from the Event ID drop-down list.
> 2. To search down in the event list, select Down in the Direction group. To search up, select Up.
> 3. Optionally, you can define search criteria for the event. Click Add. The New Attribute window appears. In this window, select the attribute by which you want to search from the Attribute drop-down list. In the Value field, type the search criteria for the attribute. For example, if you want to search for Session Started events from a certain client host (such as 'sales1.company.com'), you would select Session Started in the Find Event window, click Add, select ClientInfo from the Attribute drop-down list, and type `sales1.company.com` in the Value field.
> 4. Click Find Next to find the next event.
> 3. Optionally, you can filter the search to display only specific events in the Details pane. To do this, click the Service Event Trace node of a service; then, select View / Filter. The Filter window appears.

> In this window, perform one of the following actions:

> - Select the events you want to view from the Events to View list. To select non-adjacent events from the list, hold down the CTRL key while selecting the events. To select adjacent events from the list, hold down the SHIFT key while selecting the events.
> - Select the types of events you want to view by selecting the appropriate Event Types check boxes. When you select an event type, the corresponding events are highlighted in the Events to View list.
> 4. To view information about a specific event, right-click an event in the Details pane, and select Properties. The Event Properties window appears.
> 5. Click the Attributes tab to view the attributes for that event.
