Log streaming: Logentries

Fastly's Real-Time Log Streaming feature can send log files to Logentries. Logentries is a real-time log management and analytics system that you can use to monitor your Fastly logs.

Prerequisites

  1. Register for a Logentries account.
  2. Create a new log in the Logentries application by following the instructions on the Logentries website
  3. During new log creation, select Manual Configuration and Token TCP.
  4. Make a note of the token provided in the Logentries configuration panel. We recommend you use this token when you create the Logentries logging endpoint for Fastly services.

Adding Logentries as a logging endpoint

After you've created a new log in Logentries and found the token, follow these instructions to add Logentries as a logging endpoint for Fastly services:

  1. Review the information in our Setting Up Remote Log Streaming guide.
  2. Click the Logentries logo. The Create a new Logentries endpoint page appears.

    the create a new Logentries page

  3. Fill out the Create a new Logentries endpoint fields as follows:

    • In the Description field, type a human-readable name for the endpoint.
    • In the Log format 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. Our discussion of format strings also provides more information.
    • In the Port field, type 20000. Though we recommend this specific setting when adding your endpoint, there are additional options to consider when deciding on the port, TLS, and token settings.
    • From the TLS menu, select Yes.
    • In the Token field, type the token provided in the Logentries configuration panel.
  4. Click the Create button to create the new logging endpoint.

  5. Click the Activate button to deploy your configuration changes.

Additional selections for ports, TLS, and tokens

The Port, TLS, and Token selections shown above are what we recommend when you add a Logentries endpoint. However, you do have other choices when you add your endpoint.

Using your port number. You can add a Logentries endpoint by using your secret Logentries port number (e.g., 56789). However, we strongly recommend sending your logs via TLS. To do this, set TLS to Yes and add 10000 to your secret port number (e.g., 66789). See the Logentries guide Plain TCP/UDP for more information.

Using your token. You can add a Logentries endpoint by using your secret account token. To use your token, set your port to 10000. However, we strongly recommend sending your logs via TLS. To do this, set TLS to Yes and the port number to 20000. See the Logentries guide Token TCP for more information.

Next steps

Logentries maintains the Fastly Community Pack that leverages custom VCL to provide advanced User-Agent statistics, regional statistics, error tracking, and more.
