Dashboard Issues
Empty widgets, stale data, or broken share links.
Symptoms
- Widget shows no value or "empty"
- Share link
/share/:tokenreturns error - Historical chart flat or missing
Checklist
- Tag path — widget tag path must exist and match UNS exactly (
plant/machine/device/tag) - Telemetry — confirm live value in UNS Explorer
- Time range — stat/timeseries/bar/timeline window includes data
- Share token — link not revoked; shared dashboard only exposes widget tag paths
- Public API host — share page uses same API origin as console
Widget types
Stat and gauge need one tag; timeseries, bar, and timeline support multiple tags with palette colors. Stat widgets also load history for the mini-sparkline (same window control as timeseries).
