Configure Global Log Receiver

Published April 5, 2023 | Last modified June 27, 2025

Objective

This guide provides instructions on how to enable sending of your tenant logs from F5® Distributed Cloud Regional Edge (RE) Sites to an external log collection system. The sent logs include all system and application logs of your tenant. This also includes logs of all Customer Edge (CE) Sites of that tenant. For conceptual information about logging, see Logs.

A folder gets created each day in your log collection system and in that folder, a folder for each hour gets created. The logs are sent for every 5 minutes into the hourly folder and are stored in a compressed gzip file.

Global log receiver supports sending the logs for the following log collection systems:

  • AWS Cloudwatch
  • AWS S3
  • Azure Blob Storage
  • Azure Event Hubs
  • Datadog
  • GCP Bucket
  • Generic HTTP or HTTPs server
  • IBM QRadar
  • Kafka
  • NewRelic
  • Splunk
  • SumoLogic

Note: Currently, global log receiver supports only sending the request (access) logs, security events, and audit logs for all HTTP load balancers and sites.

Using the instructions provided in this guide, you can configure a Global Log Receiver in the F5® Distributed Cloud Console (Console) to enable sending of logs to an external log collection system.

Prerequisites

Enable Global Receiver of Logs

You can configure global log receiver in either system namespace (Multi-Cloud Network Connect service) or in shared namespace (Shared Configuration service). In case of configuring in shared namespace, you can configure to send from either shared namespace or all namespaces or specific list of namespaces. If you are configuring in system namespace, you can only send logs from system namespace.

The example shown in this guide creates a global log receiver object in the Console in system namespace for sending the logs to the external log collection system.

Step 1: Start creating a global log receiver.

  • In the Console home page, select the Multi-Cloud Network Connect service or the Shared Configuration service.

    • Multi-Cloud Network Connect service: Select Manage > Log Management > Global Log Receiver.
    • Shared Configuration service: Select Manage > Global Log Receiver.

  • Select Add Global Log Receiver.
Step 2: Configure global log receiver properties.

  • Enter a name in the Metadata section. Optionally, set labels and add a description.

  • From the Log Type menu, select Request Logs, Security Events, Audit Logs, or DNS Request Logs. The request logs are set by default.

  • In case of Multi-Cloud Network Connect service, select logs from current namespace from the Log Message Selection menu. This is also the default option.

  • In case of Shared Configuration service, you can select one of the following options:

    • Select logs from current namespace: This option sends logs from the shared namespace. In case of DNS Request Logs, sending logs from the current namespace is not supported. Either select logs from all namespaces or select logs from specific namespaces, and select the system namespace to send logs from.
    • Select logs from all namespaces: This option sends logs from all namespaces.
    • Select logs in specific namespaces: This option sends logs from specified namespaces. Enter the namespace name in the displayed namespaces list. Use Add item to add more than one namespace.

  • From the Receiver Configuration drop-down menu, select a receiver and follow the corresponding instructions below.

  • Select Server CA Certificates for the Trusted CA field. Enter the certificates in PEM or Base64 format in the Server CA Certificates box.
  • Select Enable mTLS from the mTLS config menu and enter client certificate in PEM or Base64 format in the Client Certificate box.
    • Select Configure in the Client Private Key field, enter the secret in the box with type selected as Text.
    • Select Blindfold, wait for the operation to complete, and click Apply.
Step 4: Complete log receiver creation.

Select Save and Exit to complete creating the global log receiver.

Step 5: Inspect your connection and verify that logs are collected in the receiver.
  • Select ... > Test Connection in the Actions column for your global log receiver object. Wait for the test to complete and return message indicating successful connection.

Note: The F5 Distributed Cloud performs up to 20 retries in case of connection failure. The retries are performed only in case of the following HTTP response codes are returned:

  • 429
  • 500 and above, but not 501
  • Verify that logs are collected into your receiver (such as S3 bucket in AWS).
