The following describes the items displayed in the Preferences window.
- Automatic refresh
-
Specifies whether the information displayed on the Monitor Events and Severe Events pages is to be refreshed automatically.
Selecting Apply and specifying in seconds the refresh interval in the Interval text box enables automatic refresh. You can specify a value from 1 to 10,000 (seconds). The default is 5.
Selecting Do not apply disables automatic refresh.
- Scroll buffer
-
Specifies the maximum number of events that can be displayed on the Monitor Events, Severe Events, and Search Events pages in the Event Console window.
You can specify a value from 10 to 2,000 (events). The default is 500.
In Web-based JP1/IM - View, the range of specifiable values is from 10 to 1,000, and the default is 100.
The Scroll buffer value must be greater than the Num. of events to acquire at update value and the Num. of events to acquire in 1 search value.
If the Scroll buffer value is too small, the pages might not be able to display all the JP1 events.
If the current value is increased, the change is applied the next time the window is refreshed, whether automatically or manually.
If the specified value is too large when JP1/IM - View is started, the Event Console window might take longer to appear.
Before setting the scroll buffer, the user must estimate the amount of required memory for Central Console - View, and must check the amount of free space on the machine resource. For details about the formula for estimating the amount of required memory, see the Release Notes for JP1/IM - View.
- Num. of events to acquire at update
-
Specifies the number of events that can be acquired from the event console service in one refresh operation for the Event Console window. A refresh operation is performed at the interval specified in the Automatic refresh area of the Preferences window, or whenever the user chooses View and then Refresh in the Event Console window.
When automatic refresh is enabled, refresh operations are repeated until no JP1 events remain in the event buffer of the event console service.
The range of specifiable values is from 1 to 200. The default is 20.
The Num. of events to acquire at update value must be smaller than the Scroll buffer value.
- Num. of events to acquire in 1 search
-
Specifies the number of events that can be acquired in one event search operation.
The range of specifiable values is from 1 to 2,000. The default is 20.
In Web-based JP1/IM - View, the range of specifiable values is from 1 to 1,000, and the default is 20.
The Num. of events to acquire in 1 search value must be smaller than the Scroll buffer value.
