Hi
Just wanted to put this on the community in case other AppD users come across it and need a solution.
Problem
When the Application has not data coming in for Errors per min or no load to have an Average Response time, (present in a lot of pre-prod apps) then the metric value Widgets on the Custom Dashboard will display dashes (--) instead of numerical values, like a zero.
AppD Support input
AppD says that there is a flag on the controller settings that is related to this and displaying null operands for metric expressions. They informed us on the support ticket that they have enabled it for our SaaS Controllers (v22.6)
They also showed us how to update the Widgets to use a metric expression instead of the default configuration.
Solution
Update all the affected Metric Value Widgets to use a metric expression that does not affect the metric values in any way we do not want.
Example: {errors} + 0
See screenshots below for more details.
