Configure Optimizely Agent

How to configure Optimizely Agent with a comprehensive list of available configuration properties.

Optimizely Agent uses the configuration file in the active directory by default. For example, ./config.yaml. You can override the default configuration by providing a YAML configuration file at runtime.

You can specify alternative configuration locations at runtime using an environment variable or command line flag:

OPTIMIZELY_CONFIG_FILENAME=newconfig.yaml make run

You must configure Real-Time Segments for Feature Experimentation to use:

OPTIMIZELY_CLIENT_ODP_DISABLE
OPTIMIZELY_CLIENT_ODP_EVENTSREQUESTTIMEOUT
OPTIMIZELY_CLIENT_ODP_EVENTSFLUSHINTERVAL
OPTIMIZELY_CLIENT_ODP_SEGMENTSREQUESTTIMEOUT
OPTIMIZELY_CLIENT_ODP_SEGMENTSCACHE

Below is a comprehensive list of available configuration properties.

More information about configuring Agent can be found in the Advanced Configuration Notes.

To use a PROXY server the following environment variables can be used:

Environment variable	Description
HTTP_PROXY	HTTP URL of the proxy server to use for every request.
HTTPS_PROXY	HTTPS URL of the proxy server to use for every request. It takes precedence over HTTP_PROXY for HTTPS requests.
NO_PROXY	Defines that no proxy should be used.

The environment values may be either a complete URL or a host[:port], in which case the http scheme is assumed. The schemes http, https, and socks5 are supported. To read more about proxy configurations, view the Go documentation on net/http.
