Log streaming: Sumo Logic

Fastly's Real-Time Log Streaming feature can send log files to Sumo Logic. Sumo Logic is a web-based log analytics platform used by developers and IT teams.

Setting up Sumo Logic

To use Sumo Logic as a logging endpoint, you'll need to create a Sumo Logic account, add a new source, and save the HTTP Source URL. Follow these instructions to add a new source in the Sumo Logic website:

  1. The process starts with the Sumo Logic Setup Wizard, which appears immediately after you create your Sumo Logic account. If you already have an account, you can access the wizard by selecting Setup Wizard from the Manage menu at the top of the Sumo Logic application.

  3. Fill out the New Sumologic endpoint fields as follows:

    • In the Name field, type a human-readable name for the endpoint.
    • In the Collector URL field, type the address of the HTTP Source URL you found in the Sumo Logic website.
    • In the Format String field, optionally type an Apache-style string or VCL variables to use for log formatting. The Apache Common Log format string appears in this field by default. See our guidance on format strings for more information.
  4. Click Create to create the new logging endpoint.


The Sumo Logic logging endpoint is designed for services with sustained levels of traffic. If you aren't seeing any logs in Sumo Logic, try waiting a bit.
