Event Viewer Tab

The Event Viewer is a read-only screen displaying all events detected by the Web Client as they occur throughout the monitored systems. An Event Viewer screen within the Web Client looks like the one below.

You will notice that there is a vertical scroll bar enabling you to scroll up or down through a list of all currently recorded events. Events are color-coded by Event Type.

The columns that describe each event are described below:

Host Time	The date and time this event occurred as recorded by the Velocity host.
Controller Time	The date and time this event occurred as recorded by the controller reporting the event. This value will be different from the Host Time only if the controller is located in a different time zone, or if there is a delay between the time the event occurs on the controller and the time when it is received by the host.
Description	A brief description of the event. This should supply a message indicating what the event was.
Address	The unique address assigned to this event. This indicates the exact point where the event took place.
Event Type	The type of event that occurred. Many different types of events are tracked by the system; DIGITRAC External, DIGITRAC Internal, Software, Communications, Port, Controller, and so on. For more about this, refer to Event Types.
Event ID	The ID associated with this event. Each event has a unique Event ID.
Configure Column Headers	For more details refer Configure Column Headers.

Event Types

Click on the Filter Events By Type field so that the dropdown list of the available Event Types appear. Select one or more Event Types; the Event Viewer will only display the chosen filter events. The columns that describe each event type and ID range are mentioned below.

Event Type	Event ID Range	Description
Software	1001 - 1099	An event generated by the software.
Access	2000 - 2033	An event based on the type of access.
Internal	9001 - 9099	An event recorded within the device, such as a time zone change or a database correction.
External	4001 - 4099	An event was recorded at the attached device.
Alarm	5001 - 5999	An event that triggers an alarm, such as a DOTL or entry delay error.
Programming	8600 - 8750	An event that triggers when a programming mismatch or is not configured correctly.
Xbox	7000 - 7047	An event based on Xbox type.
Misc	8001 - 8499	An event that does not fit into any other category.
Ports	8501 - 8599	Events specific to the port, such as a port socket or port offline error.

Suspend scrolling of Events

In some situations, you may need to suspend scrolling temporarily. Doing so freezes the Event Viewer at the current spot and stops displaying new events.

Some reasons for suspending scrolling are:

Events are happening faster than the operator can monitor
An important event occurred and the operator wants to freeze the screen at that point

To temporarily Suspend/Resume scrolling:

Right-click anywhere within the Event Viewer screen and click Suspend scrolling.
This feature is available on all the tabs where the Event Viewer is displayed. Please refer to the Settings→Events tab for more information.
The background color on the screen changes (unless the normal and the suspended color values are the same), and the Event Viewer stops displaying new events until you Resume scrolling.
To Resume scrolling, right-click anywhere on the Event Viewer screen and click Resume scrolling.

Suspended scrolling is a temporary setting that is not saved and will revert back to scrolling when you refresh or go in and out of the Event Viewer tab. Events are not lost while scrolling is suspended; their display is just postponed. The Event Viewer caches any new events in a queue, and when scrolling resumes, these cached events are displayed in the Event Viewer at a rapid rate.
