    Frequently Asked Questions

    How the FeatureServer scorecard works.

    What exactly is graded?
    Five categories, equally weighted: response time (two live requests, averaged), schema quality (field aliases, coded-value domains, naming), data completeness (null density across a 100-record sample), maintenance (how recently the layer was edited), and configuration (Query capability, maxRecordCount, geometry). The total maps to a letter from A to F.
    Is my token stored anywhere?
    No. Tokens are used only for the live requests during grading. The cached scorecard behind the share link contains scores and notes only — never credentials.
    My service scored lower than expected — now what?
    Each category note tells you what pulled the score down — missing aliases, stale edits, sparse attributes. Most fixes are quick wins in ArcGIS Online item settings. To catch regressions automatically, add a free GISGP health monitor: it pings the service hourly and emails you the moment something breaks.
