HPA Portal sections Data Point Selectors DPS - Full worked example

One real DPS followed step by step, from the metrics it selects to the row it returns.

Use case: the average CPU of the DataServer on hex-perf20 during the November 2025 analysis week, counting only the moments it was busy (10 % or more).

Field Value
Display name CPU average (Nov 2025 week)
Agent hex-perf20|v172312|DataServer
Metric name CPU:.*
Metric type VALUE, Effective metric only checked
Operator / Value 1 Greater than or equal to / 10
Reduce scope / Reduce function One per series / Average
Resample target points 60
Time period selector Nov 2025 analysis week: 2025-11-19 01:00 → 2025-11-26 01:00

List metrics shows the two metrics the name matches:

Metrics matched by the DPS

Step CPU:Processor Count CPU:Utilization % (process)
1. Metric type VALUE 8 all the time (the number of cores) 0 to 95 %
2. Values filtering ≥ 10 every point removed the points ≥ 10 kept
3. Reduce One per series, Average no point left: no value, the series is dropped average of the points kept
4. Resample no effect: one value per series no effect
Result absent its average

DPS evaluation result

  • a series left without any point has no value and is not shown, not even as an empty row
  • removing the value filter, or setting it below 8, brings CPU:Processor Count back in the result
