The formula used to calculate whether this metric is marked as an issue in the grid and Summary window. When a metric is marked as an issue, it is distinguished as follows:
In the Summary window, the metric value is shown with a pink background, and a block of issue text appears under the metric name and value.
In the grid, issues are determined on a per-row basis. A cell that is determined to be an issue for a given metric is shown with a pink background, and a tooltip displaying the issue text appears when you mouse over the problem cell.
issue_eval formulas are specified exactly as
formula()can be used as shorthand to stand for the metric
formulaattribute for this architecture.
The comparison operators (for example, < ) are used to tie the final value to 0 or non-zero. Non-zero final values are marked as issues, zero final values are not. So, for example, in the grid, the following metric will evaluate to a non-zero value if and only if the value shown in the cell (
formula()) is greater than .3 (
formula() > .3), and the row accounts for at least 5% of observed clockticks (
myMetric.issue_eval["snb"] = ( formula() > .3 ) * ( query("PMUHotspot")> .05 ):
myMetric.issue_eval["snb"] = ( formula() > .3 ) * ( query("PMUHotspot") > .05 )
This attribute must have an architecture specification.
