Set up the Global Log Receiver

Published April 5, 2023 | Last modified July 30, 2026

Overview

This guide provides instructions for setting up an F5 Distributed Cloud Global Log Receiver so that you can send your tenant logs to an external log collection system.

About the F5 Distributed Cloud Global Log Receiver

Global Log Receiver supports sending the request (access) logs, security events, DNS and audit logs for all HTTP load balancers and sites. The Global Log Receiver logs are sampled and do not contain the body of the request or response logs.

The Global Log Receiver page displays the following information:

Name: The name of the Global Log Receiver.
Namespace: The namespace in which the Global Log Receiver is created.
Status: The logging status of the Global Log Receiver. The status displays one of the following values:

Status	Description
Up	The Global Log Receiver is functioning as expected.
Down	Logging is not operational due to unreachable upstream endpoint, Global Log Receiver service outage, configuration issues, or logs not sent.
Unknown	Status detection for the Global Log Receiver failed.

The external log collection system creates a folder for each day and within that daily folder, also creates a subfolder for each hour. Every five minutes, the log collection system writes new logs to the relevant hourly subfolder as compressed gzip files. The supported log format is NDJSON (newline-delimited JSON), where each line represents a separate JSON object.

Supported log collection systems

The 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
New Relic
Splunk
Sumo Logic

Important: To use Azure Event Hubs, you must have a standard, premium, or dedicated tier subscription. For more information, refer to the How do I configure Global Log Receiver for Azure Event Hubs? article.

Before you begin

Before you begin, make sure you have:

An F5 Distributed Cloud Account. If you don't have an account, see Get Started with Console.
An external log collection system reachable publicly.
A firewall or proxy server configured to allow connections to and from the IP addresses listed in the Public IPv4 Address Ranges for F5 Global Log Receiver section of the F5 Reference for Firewall or Proxy Settings guide.

Create Global Log Receiver

You can create the global log receiver in the system namespace (Multi-Cloud Network Connect workspace) or in the shared namespace (Shared Configuration workspace). If you're using the shared namespace, you can send from either the shared namespace or all namespaces, or a specific list of namespaces. If you are using the system namespace, you can only send logs from the system namespace.

Step 1: Create a global log receiver object.

From the Console home page, select the Multi-Cloud Network Connect workspace or the Shared Configuration workspace.
In the Multi-Cloud Network Connect workspace, select Manage > Log Management > Global Log Receiver.
In the Shared Configuration workspace, 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 list, select Request Logs, Security Events, Audit Logs, or DNS Request Logs. Request Logs are the default.
For the Multi-Cloud Network Connect workspace, select logs from the current namespace from the Log Message Selection list. This is the default option.
For the Shared Configuration workspace, you can select one of the following options from the Log Message Selection list:
- Select logs from current namespace: This option sends logs from the shared namespace.
Note: For DNS Request Logs, the system doesn't support sending logs from the current namespace.
- 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 list, select a receiver and follow the corresponding instructions below.

Splunk Receiver

According to a Splunk article, there are two different Splunk HEC URIs:

For Splunk Cloud customers, the standard HEC URI is https://http-inputs-customer_stack.splunkcloud.com. Splunk Cloud customers do not need to specify port 8088. All HEC traffic goes over port 443.
For customers using AWS Firehose, you have a second HEC URL: https://http-inputs-firehose-customer_stack.splunkcloud.com.
For customers running HEC on their own deployments or using the Splunk test drive instance, you need to specify port 8088: https://input-prd-uniqueid.cloud.splunk.com:8088.

In either of the scenarios, you can use the following commands to validate the URLs:

For Splunk Cloud, enter nslookup http-inputs-<customer_stack>.splunkcloud.com.
For Splunk Test Drive, enter nslookup input-prd-uniqueid.cloud.splunk.com.

See Splunk documentation.
