Runtime Logs & Analytics

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.

Query via API

curl "https://api.mixpeek.com/v1/apps/$APP_ID/logs?log_type=requests&hours=1&limit=100" \
  -H "Authorization: Bearer $API_KEY"

      "method": "GET",
      "path": "/",
      "status_code": 200,

      "ip": "68.175.65.201"

  ]
}

Parameters

Parameter	Type	Default	Description
`log_type`	`string`	`runtime`	`runtime` or `requests`
`hours`	`integer`	`1`	Lookback window (1–168 hours)
`level`	`string`	—	Filter by log level (runtime only): `log`, `warn`, `error`, `info`

Runtime logs

Server function console output is automatically captured and stored. Each log entry includes the function route and log level.

Studio

In Studio, the App details page has an Analytics panel with three tabs:

Tab	What it shows
Overview	Error rates, web vitals, custom events
Runtime Logs	Server function console output with level badges
Requests	HTTP 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.
