Edge Delta Environment Variables

Frequently Used Environment Variables

The following environment variable parameters can be passed when you install and deploy the Edge Delta Fleet.

ED_API_KEY

Identifies and authorizes access to your Fleet’s Pipeline configuration in the Edge Delta back end.

ED_ARCHIVE_FLUSH_INTERVAL

Specifies the duration after which logs are flushed and sent to the configured archiving destination. The default value is 30m.

ED_HOST_OVERRIDE

By default, the agent fetches the host name using the operating system’s built-in methods:

• macOS: The agent calls os.HostName(), which retrieves the host name from kern.hostname.
• Linux: The agent calls os.HostName(), which retrieves the host name from /proc/sys/kernel/hostname.
• Windows: The agent calls ComputerNameEx system call, which retrieves the hostname from the kernel.

You can configure a custom name with the ED_HOST_OVERRIDE variable. This is useful to help identify agents.

export ED_HOST_OVERRIDE="custom-hostname"

Alternatively you can change the host name:

• macOS: sudo scutil --set HostName "new-hostname"
• linux: sudo hostname new-hostname

Note: This command changes the hostname temporarily. To make it permanent, additional steps, such as editing the /etc/hostname and /etc/hosts files, may be required, depending on the Linux distribution.

• windows (PowerShell): Rename-Computer -NewName "new-hostname"; Restart-Computer

ED_TAG_OVERRIDE

Specifies a tag that is different to the one configured in the Web App. Use this option to deploy two fleets with the same Pipeline configuration.

HTTP_PROXY

Uses proxy details to route the Fleet’s outbound traffic through an HTTP internal proxy.

HTTPS_PROXY

Uses proxy details to route the Fleet’s outbound traffic through an HTTPS internal proxy.

NO_PROXY

Disables the proxy for requests that hit a specific destination.

OTEL_SERVICE_NAME

Defines the resource.service.name field in Edge Delta OTEL messages.

STORE_PORT

Uses a port number to expose agent metrics storage.
