Which of the following best describes the reporting metric that should be utilized when measuring the degree to which a system, application, or user base is affected by an uptime availability outage?

The timeline refers to the chronological sequence of events leading up to and following an uptime availability outage. While the timeline provides valuable information about when the outage occurred and how long it lasted, it does not capture the full extent of the impact on the system, application, or user base.

Evidence pertains to the data, facts, or proof that support or validate the occurrence of an uptime availability outage. While evidence is crucial for understanding the causes and consequences of the outage, it does not directly measure the degree to which the system, application, or user base is affected by the downtime.

The impact refers to the effect or influence that an uptime availability outage has on the system, application, or user base. While measuring the impact is important for assessing the severity of the outage, it does not specifically quantify the breadth or coverage of the affected components.
