Server Status and Group Parameters

 

The Server status dialog periodically queries the Server object for status and displays the results. The Group Parameters dialog box queries the group state and displays the results. The OK button and Apply button in the Group Parameters dialog box write the parameters from the dialog to the Group object and read the parameters back. This primarily controls the scanning and updating of data. When a group is inactive, it does not send data notifications to the client and, typically there is no reason to scan the items when the group is inactive. The Update Rate in the Group Parameters dialog box specifies the rate at which data notifications should be sent back to the client, assuming that data have changed. This is also the rate at which items are scanned on behalf of this client.
