What it does

Once a month it reads Looker usage from BigQuery's audit log exports, computes a decay score per dashboard from how recently and how widely it was viewed, and maintains a single Coda registry that the data team works down.

When to use it

Use this when you want a durable, browsable record of dashboard health rather than ephemeral alerts. Coda becomes the system of record where owners annotate, defer, or approve retirements over time.

How it works

  1. 1A monthly schedule starts the run.
  2. 2BigQuery is queried against Looker audit log tables for views, distinct viewers, and last-view date per dashboard.
  3. 3A scoring step classifies each dashboard as Healthy, Watch, or Decay using recency and unique-viewer thresholds.
  4. 4Only Watch and Decay rows pass the filter.
  5. 5Each row is upserted into a Coda table keyed by dashboard ID, preserving prior owner notes and status.
  6. 6The Coda row carries the score, idle days, and last viewer so reviewers can act in one place.
