Log Streams


Render Log Streams forward logs from your web services, private services, background workers, and cron jobs to any logging provider that supplies a TLS-enabled syslog drain.

Service logs are delivered to the provider’s syslog endpoint via TCP, and are formatted according to RFC5424, the specification most commonly used by providers. A formatted log line would look like:

<0>1 2021-03-31T16:00:00-08:00 test-service cron-12345 74440 cron-12345 - hello this is a test

Your provider will parse the relevant details from the formatted log line. Render annotates your logs with your service slug, the type of service, and a unique identifier for the instance (you can use this to track your service between deploys, or to distinguish between multiple instances if you are running more than one).

Configuring Log Streams

To define a Log Streams endpoint, navigate to Account or Team Settings in your Render dashboard. Locate the Syslog Endpoint section and enter your endpoint URL in the format HOST:PORT, for example logs.papertrailapp.com:34302.

Log Streams can be configured for an account or a team, and apply to all supported services owned by the account or team. If you manage multiple teams on Render, please configure a log endpoint for each team separately.

Supported Providers

Render can forward your logs to any TLS-enabled syslog endpoint that expects logs formatted per RFC5424. We do not support insecure (non TLS-enabled) endpoints or providers that require a custom log format. Most steps listed by logging providers to set up Syslog (such as updating a configuration file, restarting services, etc.) are not required with Log Streams, you simply need to obtain your unique Syslog endpoint and enter it in the Render dashboard.

If you’re running into issues with Log Streams and you believe your logging provider should be supported, please let us know at support@render.com.

Where to Find Your Syslog Endpoint

Papertrail

Once you’ve logged into your account, navigate to the setup page to obtain your Syslog endpoint:

You can also optionally generate a unique endpoint for your Render services if you use the same Papertrail account for logs from services hosted on other providers.

LogDNA

Log into your account and navigate to the sources page. Select ”syslog” on the left sidebar to see your syslog endpoint.
