System-Wide Events List and Event Journal Preferences
This section summarizes those Events List or Event Journal options that a system administrator can configure on a system-wide basis. Some of the options are specific to Events Lists, whereas others affect the Event Journal. Some options affect other areas of ClearSCADA in addition to Events Lists or the Event Journal. Such options, if required to differ from the defaults, should be specified on each server when a ClearSCADA system is first installed. The options are specified using the ClearSCADA Server Configuration Tool.
You can use the ClearSCADA Server Configuration Tool to:
- Specify the Alarms section settings, including:
- Whether events are actually logged on your system. (When enabled (the default), ClearSCADA logs events in the Event Journal. Any of these events can be viewed in list format, by displaying an Events List.)
- Whether the ‘Area of Interest’ feature is enabled on your system. (For more information on this feature, see Restrict Alarm and Event Access to Specific Areas of Interest in the ClearSCADA Guide to Core Configuration.)
- Specify the Events List columns that are included in the Events Lists on your system, and the number of Events List columns that remain at a fixed size (see Events Display Settings for the Event Journal (Events List) in the ClearSCADA Guide to Server Administration).
- Specify the Location of the database files, including the Event Journal (see Locations of the Database Folders in the ClearSCADA Guide to Server Administration).
- Specify the Historic Configuration settings, including the amount of time for which Event Journal messages are kept online (see Historic Configuration Settings in the ClearSCADA Guide to Server Administration).
For more information, see Alarms Settings in the ClearSCADA Guide to Server Administration.
To access a ClearSCADA system, users typically log on via a User Account. Anyone who accesses the system without logging on, is logged on automatically via the Guest or Web User accounts.
Use the Root or System Group Form to define the system-wide settings for the Guest User, including:
- The default Event List Range.
- If the Area of Interest feature is used on your system, any Area of Interest Filters. (This can affect which events are visible to the Guest User.)
For information on configuring either of the above, see Define the Global Settings for All Guest and Web User Accounts in the ClearSCADA Guide to Security.
