Key points
- Where to look: the D1 database Overview “Rows read” chart and its Queries table sorted by rows read, checking the read/returned ratio; GraphQL dataset d1AnalyticsAdaptiveGroups (sum of readQueries and rowsRead by databaseId); and Durable Objects Metrics for requests and alarm invocations per namespace.
- His habits: index every column queried outside the primary key, run EXPLAIN QUERY PLAN on new queries and fix anything that says SCAN, and reschedule alarms only on the success path with a retry counter.
- Alert rule: flag any meter more than 10 times its 7-day median. He runs it every 6 hours with his own read-only usage-guard-collector Worker (MIT). The incident table is self-reported amounts without links, so it is not used as case evidence here.
