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.

Required UserId

Always set the UserId to uniquely identify the user or device that connects to PubNub. This UserId should be persisted, and should remain unchanged for the lifetime of the user or the device. If you don't set the UserId, you won't be able to connect to PubNub.

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