Data layer

Root Record data

The data layer is persistent system state. The RootRecord Database is where that state lives. This page names the kinds of record. It does not publish a schema, credentials, or an internal layout. There is no public runtime signal for the database itself.

• Telemetry

  Telemetry is a measurement with a time. On the public site that means network counts, the weather observation time, and the Kīlauea status. A missing measurement stays missing. The site does not draw a history when the feed has no series.

• System state

  System state is the retained picture of what the system last knew. The public pages show the last observation they were given. They do not show internal state files, process lists, or a database score.

• Weather

  The public weather record is an observation time and the fact that a Hawaiʻi report exists. Temperature, humidity, pressure, wind, and precipitation are not in that feed, so the operations page omits them. A written forecast, when one is published, lives on Reports.

• Geology

  Geology on the public feed is the Kīlauea status: alert level, color code, headline, and whether an eruption is indicated. That is context for the Hawaiʻi site. It is not a health light for the computers.

• Media, logs, and reports

  Media and logs stay in the data layer so an operation can be checked later. They are not dumped onto this website. Reports are the public summaries. The latest text for each desk is linked from Reports. A report is not a live query of the database.
