Each one-minute interval can only have the value of one impacted minute.
The values are described in the table below.
Value | Description |
|---|---|
0 | No metric triggered within the minute. |
1 | All other metrics |
3 | Fault (three bad minutes) |
10 | Blue screen (ten bad minutes) |
There are four checks for each metric in the one-minute interval.
If a metric is true within the one-minute interval, then the metric will contribute to the impact.
If the metric triggers bad health, all four of the samples will always be 1, unless there is a fault or a blue screen.
When an application fault or a blue screen occurs, it only contributes one impact minute for the one minute interval. That one impact extends for the additional amount of time.
For example, if a system has a high CPU during that minute, the system will have 1 impact minute.
If that same system has an application fault, the system will have 1 impact min for 3 total 1 minute intervals.
