Application flow chart

Omnitrend's ServScan is comprised of two main application components. The first, SSScanner.exe, is a Windows service that performs the actual monitoring for events. The second component, ServScan.exe, is the administrative tool that permits configuration of the software.

In the figure to the right, these two components are represented by the blue boxes.

There are three database components to Omnitrend's ServScan; Computer List, Notification Events List; Notification Device List. These databases are maintained using the administrator component.

The Computer List is a database of computers that can be selected when creating Notification Events. The Notification Device List is a database of devices that can receive notifications when events occur that meet the criteria for an item in the Notification Event database.

The Notification Event database is used by the SSScanner service to determine what computers should be scanned. SSScanner examines the items in the database and scans only the computers for which items are configured. Effectively, then, not all computers on the Computer List will be scanned. For efficiency, only computers for which there is a Notification Event List entry configured will be scanned.

In a nutshell, the SSScanner service scans Event Logs for which there is at least one Event Log Filter configured, process events through the filters, notifies devices if an event passes a filter, and records the notification in the Notification Log file.

Note that the ordering of filters in the Notification Events List is important. Events are processed through the filters in order. Once the event passes a filter, it not be processed through the remaining filters in the list... even if that event meets the selection criteria for a filter farther down the list.
