Lists Guide - Display a General List of Events (Events Lists)

Display a General List of Events

You can display a list of events that have occurred on a single Geo SCADA Expert system (database). The List is pre-filtered by time—the period for which events are initially shown is defined by your User Account (or the Guest User Account if you are not logged on to Geo SCADA Expert).

Any events that relate to alarms are displayed in the same color scheme as used on the Alarms List (see The Color of Entries in a List other than the Alarms List).

Be aware that your user account settings, security permissions and so on, may restrict the events to which you have access. This is to help ensure that you are only made aware of events that might be of interest to you.

To display a general list of events on a ViewX client or Virtual ViewX client, either:

Select the Home tab on the ViewX ribbon.
Select the Events command from the relevant command group.

Or:

Press the F10 function key (ViewX clients only).

An Events List is displayed. The List shows event messages that have been logged on your system within a specified time period (the Event List Range specified on your User Account (or the Guest User Account if you are not logged onto Geo SCADA Expert)).

If the Events List is not displayed and a Historic Cache message is shown, there are too many events for the query to process. To avoid this, you may need to further filter the Events List (see Filter a List). (If the filter does not resolve the situation, contact a high-level user as the amount of memory available may be inadequate, or the configuration of database items may mean that events are being logged more often than are actually required.)

You can refresh the Events List by:

Selecting the Refresh Query option from the List's context-sensitive menu
Pressing F5 (ViewX clients only) .

For more information, see Refresh the Data on a List other than an Alarms List.

NOTICE

LOSS OF DATA

There is a limit to the number of Event Journal records per database item per hour that can be logged. If the number of records for an individual item reaches this limit an alarm is raised to indicate that the granule has reached the maximum value and no more events will be logged for the item for the remainder of this period. This will result in the loss of data that has been discarded. To help prevent loss of data, you need to set appropriate maximum values, see Define the Acceptable Number of Event Journal Records.

Failure to follow these instructions can result in loss of data

On a ViewX client that has access to multiple Geo SCADA Expert databases, the above procedures each display the general Events List for the default Geo SCADA Expert database. To display the Events List for a particular Geo SCADA Expert database to which a ViewX client has access:

Display the Database Bar (see Display an Explorer Bar).
1. Right-click on the relevant system entry.
  A context-sensitive menu is displayed.
Select the Display Events option.
The list of events for that Geo SCADA Expert system is displayed.
