Examples of org.rhq.core.domain.discovery.AvailabilityReport

org.rhq.core.domain.discovery.AvailabilityReport
Contains a set of one or more {@link Availability} values used to indicate the statuses of a set of resources. Notethat only the {@link Availability#getStartTime() start times} are used when looking at the resource times - the endtimes found in the {@link Availability} objects are ignored. This is because a report only defines a snapshot in time- at a particular time (the availabilities' start times) a resource was either up or down. Reports do not tell you the span of time a resource was up or down, it only tells you what state they were in at a particular millisecond in time. @author Jay Shaughnessy @author Greg Hinkle @author Joseph Marques
