Operational Reliability Reports

Incident Queue Reliability

Count Visible Severity

A queue report can stay deterministic by keeping severities in a local list and deriving counts from a selected threshold. The selector changes which severities are visible.

Program

Play the program to choose a severity threshold and inspect the queue counts.

incident_queue_reliability_report.dart 
void main() {
  var minSeverity = ;
  var severities = [1, 2, 3, 3];
  var visible = severities.where((severity) => severity >= minSeverity).length;
  var high = severities.where((severity) => severity >= 3).length;
  var line = 'min=$minSeverity visible=$visible high=$high';
  print(line);
}

void main() {
  var minSeverity = ;
  var severities = [1, 2, 3, 3];
  var visible = severities.where((severity) => severity >= minSeverity).length;
  var high = severities.where((severity) => severity >= 3).length;
  var line = 'min=$minSeverity visible=$visible high=$high';
  print(line);
}

void main() {
  var minSeverity = ;
  var severities = [1, 2, 3, 3];
  var visible = severities.where((severity) => severity >= minSeverity).length;
  var high = severities.where((severity) => severity >= 3).length;
  var line = 'min=$minSeverity visible=$visible high=$high';
  print(line);
}
severity threshold `minSeverity` chooses which incidents are visible in the report.
where length Filtering with `.where(...).length` gives a count without mutating the list.
independent high count The `high` count stays fixed because it always uses severity `>= 3`.
