Real-time logs is helpful for immediate feedback, such as the status of a new deployment. Real-time logs captures [invocation logs](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/workers/observability/logs/workers-logs/#invocation-logs), [custom logs](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/workers/observability/logs/workers-logs/#custom-logs), errors, and uncaught exceptions. For high-traffic applications, real-time logs may enter sampling mode, which means some messages will be dropped and a warning will appear in your logs. Caution Real-time logs are not available for zones on the [Cloudflare China Network](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/china-network/). ## View logs from the dashboard To view real-time logs associated with any deployed Worker using the Cloudflare dashboard: 1. In the Cloudflare dashboard, go to the **Workers & Pages** page. [Go to **Workers & Pages** ↗](https://dash.cloudflare.com/?to=/:account/workers-and-pages) 2. In **Overview**, select your **Worker**. 3. Select **Logs**. 4. In the right-hand navigation bar, select **Live**. ## View logs using `wrangler tail` To view real-time logs associated with any deployed Worker using Wrangler: 1. Go to your Worker project directory. 2. Run [npx wrangler tail](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/workers/wrangler/commands/general/#tail). This will log any incoming requests to your application available in your local terminal. The output of each `wrangler tail` log is a structured JSON object: ```json { "outcome": "ok", "scriptName": null, "exceptions": [], "logs": [], "eventTimestamp": 1590680082349, "event": { "request": { "url": "https://www.bytesized.xyz/", "method": "GET", "headers": {}, "cf": {} } } } ``` By piping the output to tools like [jq ↗](https://stedolan.github.io/jq/), you can query and manipulate the requests to look for specific information: ```sh npx wrangler tail | jq .event.request.url ``` ```sh "https://www.bytesized.xyz/" "https://www.bytesized.xyz/component---src-pages-index-js-a77e385e3bde5b78dbf6.js" "https://www.bytesized.xyz/page-data/app-data.json" ``` You can customize how `wrangler tail` works to fit your needs. Refer to [the wrangler tail documentation](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/workers/wrangler/commands/general/#tail) for available configuration options. ## Limits Note You can filter real-time logs in the dashboard or using [wrangler tail](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/workers/wrangler/commands/general/#tail). If your Worker has a high volume of messages, filtering real-time logs can help mitigate messages from being dropped. * Real-time logs does not store Workers Logs. To store logs, use [Workers Logs](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/workers/observability/logs/workers-logs). * If your Worker has a high volume of traffic, the real-time logs might enter sampling mode. This will cause some of your messages to be dropped and a warning to appear in your logs. * Logs from any [Durable Objects](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/durable-objects/) your Worker is using will show up in the dashboard. * A maximum of 10 clients can view a Worker's logs at one time. This can be a combination of either dashboard sessions or `wrangler tail` calls. * When using `wrangler tail` with [WebSocket event handlers](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/workers/runtime-apis/websockets/), any `console.log` statements within those handlers are hidden until the WebSocket client closes the connection. Once the `close` is received, all messages are flushed, printing everything to the terminal at once. ## Persist logs Logs can be persisted, filtered, and analyzed with [Workers Logs](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/workers/observability/logs/workers-logs). To send logs to a third party, use [Workers Logpush](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/workers/observability/logs/logpush/) or [Tail Workers](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/workers/observability/logs/tail-workers/). ## Related resources * [Errors and exceptions](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/workers/observability/errors/) \- Review common Workers errors. * [Local development](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/workers/local-development/) \- Develop and test your Workers locally. * [Workers Logs](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/workers/observability/logs/workers-logs) \- Collect, store, filter and analyze logging data emitted from Cloudflare Workers. * [Logpush](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/workers/observability/logs/logpush/) \- Learn how to push Workers Trace Event Logs to supported destinations. * [Tail Workers](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/workers/observability/logs/tail-workers/) \- Learn how to attach Tail Workers to transform your logs and send them to HTTP endpoints. * [Source maps and stack traces](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/workers/observability/source-maps) \- Learn how to enable source maps and generate stack traces for Workers.
