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.
Location breakdown
- Location at summon DERIVED
- Space names from the group's last ping before summoned_at; overlapping spaces are one combined label, so a group counts once. A stale device attributes the group to wherever it last reported.
- Unknown (no location ping) DERIVED
- Groups with no ping at all before their summon.
- Groups MEASURED
- Count of arrivals (summoned and served) from that location in the interval.
- All locations row DERIVED
- The same summon → arrival aggregate over every group regardless of location.
- Dimmed rows DISPLAY
- Locations with fewer than 5 groups — too small a sample to trust.
