MetricAssessment rates CPU (SQL/other), batch requests, compilations (against batches), page life expectancy (300 s per 4 GB buffer pool, average and dips over 50 %, max server memory unset), user connections, memory grants pending, processes blocked and disk latency as OK, Bemærk or Reagér with a concrete next step and link, plus a plain Danish "Hvad betyder det?" for each. Shown under every graph on the instance page (now all eight metrics) and in the analysis, per drive in the disk table, and in the analysis PDF.
