Data sources
- State transition log MEASURED
- Every state change of every queue entry (join, summon, serve, …) with a server timestamp. The backbone of every number on this dashboard.
- Location pings MEASURED
- Device reports: which named venue spaces the device is in, battery level, timestamp. Cadence is device-driven — gaps of minutes are normal, and a dead or offline device simply stops pinging, so any 'location' is only as fresh as the last ping.
- Group size SELF-REPORTED
- Declared by the visitor when joining the queue. Every people-count on the dashboard scales by it.
- Queue configuration CONFIG
- Capacity, estimated view time, summon expiry windows, open/close times — settings, not observations.
Per-visit anchor timestamps
- joined_at MEASURED
- The Join Queue transition.
- summoned_at MEASURED
- The last Summon / Force Summon before the serve — the one the visitor actually acted on, so postpone-and-resummon cycles don't distort the walk time. For never-served groups, the first summon.
- served_at MEASURED
- The Serve transition — the staff button-press, used as a proxy for arrival.
- completed_at ASSUMPTION
- The Complete transition, fired by a timer ≈ the configured estimated view time after the serve.
Intervals, statistics & sync
- Interval (from / to, presets) DERIVED
- Whole Hobart days, inclusive. A visit belongs to the interval if its join falls inside it. Default: the 30 days ending on the latest event in the database.
- data through … MEASURED
- The newest transition synced into the local stats database (the sync watermark). The ↻ refresh button pulls anything newer from the source.
- average / median / P95 / P99 DERIVED
- Mean and interpolated percentiles over the per-group durations in the interval. P95 = 95% of groups were at or below this value; P99 shows the worst-case tail.
- n= MEASURED
- How many groups had both endpoints of that metric recorded — the sample the statistics are computed over.
Exhibit metrics
- groups joined / served MEASURED
- Entries whose join falls in the interval; “served” is the subset that reached Serve.
- Time in queue (join → summon) DERIVED
- summoned_at − joined_at (for the rare direct serves, served_at − joined_at). Includes groups that were summoned but never arrived. A visitor who postpones inflates their own queue time — the delay was their choice.
- Summon → arrival (summon → serve) DERIVED
- served_at − summoned_at, only where both exist. Serve is the staff button-press, so this includes staff reaction time, and groups that never arrived are excluded — it only describes successful arrivals.
- Time in exhibit (serve → complete) ASSUMPTION
- completed_at − served_at. Complete is timer-fired at ≈ the configured view time + ~5 s, so this metric essentially echoes configuration (Breathe median 8m 25s vs 500 s configured; Confessional 3m 05s vs 180 s). It is not a measurement of how long people really stayed — true dwell would have to come from location pings.
