Types of Monitors and Their Usage 

Use

In the J2EE Engine monitoring framework there are two types of monitors – performance monitors and non-performance monitors:

·        The performance monitors have history and alerting mechanisms, which includes thresholds (used to compare the actual monitored value with a predefined value and according to the result, to map a color to the monitor and create alerts).

The performance monitors are:

¡        availability monitor

¡        integer monitor

¡        long monitor

¡        frequency monitor

¡        quality-rate monitor

¡        duration monitor

·        The non-performance monitors do not have history and apart from the state monitor, no alert mechanisms.

The non-performance monitors are:

¡        text monitor

¡        state monitor

¡        table monitor

¡        version monitor

¡        configuration monitor
