3.5.1 Mechanism of the suppression of monitoring of a large number of events

The suppression of monitoring of a large number of events is performed by JP1/IM - Manager, JP1/IM - View, and JP1/Base. The suppression of monitoring of a large number of events enables you to consolidate, on JP1/IM - View, the monitored events that hinder event monitoring in order to suppress the display of those individual events in the event list. The suppression of monitoring of a large number of events enables you also to suppress the execution of the automated actions that are triggered by those events. Monitoring of dummy events cannot be suppressed.

The following table describes the roles of JP1/IM - Manager, JP1/IM - View, and JP1/Base in the suppression of monitoring of a large number of events.

Table 3‒14: Roles of individual products in the suppression of monitoring of a large number of events

Product name	Role of product
JP1/IM - Manager	Determines whether the events acquired from the event service are the events that occur in large numbers. (Registration of a large number of events in the event database of the manager cannot be prevented.) Suppresses the execution of the automated actions that are triggered by a large number of events.
JP1/IM - View	Suppresses the display of a large number of events.
JP1/Base	Prevents a large number of events from being registered in the event database of the manager.

The following separately illustrates the roles of JP1/IM - Manager and JP1/Base in the mechanism of suppressing the monitoring of a large number of events:

Mechanism of suppressing the monitoring of a large number of events (JP1/IM - Manager)

JP1/IM - Manager suppresses the monitoring of a large number of events by treating them as repeated events.

JP1/IM - Manager acquires monitoring-target events (that have passed through the event acquisition filter) from the event service, and then compares them with a repeated event condition set by the user. In the repeated event condition, the user must set the event condition to determine whether to suppress events when they occur in large numbers and the threshold for determining whether the events have occurred in large numbers.

When a monitoring-target event meets the following conditions, JP1/IM - Manager determines that the acquired monitoring-target event is one of the events that have occurred in large numbers, and suppresses its monitoring.

• The monitoring-target event meets the event condition set in the repeated event condition.

• The number of monitoring-targets that have occurred exceeds the set threshold.

Mechanism of suppressing the monitoring of a large number of events (JP1/Base)

When a large number of JP1 events have occurred, JP1/Base suppresses the forwarding of the JP1 events to the manager by using the forwarding setting file (forwarding filter) for the relevant agent.
