Troubleshooting PubNub Ruby SDK

How to enable logging

By default the PubNub SDK keeps logs in pubnub.log located in the script direcotry. You can pass a custom logger as :logger parameter during initialization of the client.

Note

Always set the UUID to uniquely identify the user or device that connects to PubNub. This UUID should be persisted, and should remain unchanged for the lifetime of the user or the device. Not setting the UUID can significantly impact your billing if your account uses the Monthly Active Users (MAUs) based pricing model, and can also lead to unexpected behavior if you have Presence enabled.

logger = Logger.new(...)
logger.level = Logger::DEBUG

pubnub = Pubnub.new(
    subscribe_key: :demo,
    publish_key: :demo,
    logger: logger
)

How to find the version of your SDK

The version is contained in the VERSION constant in the Pubnub module.
