Which field in a metric table contains the time duration that an incident is open?

The field in a metric table that specifically contains the time duration that an incident is open is the Duration Field. This field is designed to capture the length of time from when the incident is created until it is resolved. It provides critical insights into the efficiency of incident management processes and helps organizations track performance metrics related to incident resolution.

In contrast, the other fields may not directly represent the 'open' time for incidents. The Value Field typically holds numerical data relevant to metrics but does not specifically measure time duration. The Time Field often refers to timestamps related to specific events rather than ongoing durations. The Incident Field is usually focused on descriptive identifiers of incidents and thus does not encompass duration information.
