Overview

Canvas captures two types of runtime data for every app:
  • Request logs — every HTTP request hitting your app (method, path, status, duration)
  • Runtime logs — console.log/warn/error/info output from server functions
Both are stored in ClickHouse with a 30-day retention and queryable via API or Studio.

​
Request logs

Every request to your Canvas app is logged automatically — no configuration needed.

In Studio, the App details page has an Analytics panel with three tabs:
TabWhat it shows
OverviewError rates, web vitals, custom events
Runtime LogsServer function console output with level badges
RequestsHTTP request log with method, path, status, and duration
Both log tabs auto-refresh every 10 seconds and support filtering by time range and log level.
