( 4Automatic analysis is the immediate analysis of an event that has been captured and decomposed by Compaq Analyze as soon as the event is generated by the system (or shortly thereafter). No user intervention is required, and as long as the Director is running, Compaq Analyze analyzes any incoming events, regardless of any interfaces that may be running. Automatic analysis is always enabled. Be aware that automatic analysis does not use the time stamp information associated with events, rather events are assumed to have occured when the Director receives them.
( è Problem reports resulting from automatic analysis are sent to all interfaces and to all recipients that are set up to be notified. See Chapter 7 for information about setting up notification services.
8 Scavenge
( Automatic analysis processes events as they occur. However, when the Director is stopped, Compaq Analyze creates a marker that indicates the last event from the binary log file that was processed. When the system is restarted, Compaq Analyze processes all the events that occurred after the marker was created. This operation is referred to as scavenging. The scavenge operation finds events that are still pending processing and ensures that no events are missed, even when the system is restarted. The first time scavenge occurs, it processes the entire event log. Once this is complete, new events are processed as they occur. The scavenge operation always occurs four minutes after the Director is started. If the Director is started and stopped within four minutes, no scavenge occurs.
( é Initially, the entire system event log is read to find any events that can be analyzed. A filter is then applied to the analyzable events. All the events that occurred within a week of the most recent analyzable event are processed.
( ¢If there are no analyzable events, the scavenge feature becomes dormant and a marker representing an unsupported system is added to the scavmark.dat file. As long as the scavmark.dat file containing the unsupported system marker is present on the system, no scavenging occurs. If there is at least one recognized event, scavenging occurs every time the Director is stopped and started.
