Logging

This page provides logging tips to help you debug your applications.

Accessing the Logger

Logging is enabled by default in this library using Ruby's standard Logger class.

You can access the library logger with the logger property of Google::Apis.

Log Level

You can set the logging level to one of the following:

• FATAL (least amount of logging)
• ERROR
• WARN
• INFO
• DEBUG (most amount of logging) In the following code, the logging level is set to DEBUG and the Google Plus API is called:

require 'google/apis/plus_v1'

Google::Apis.logger.level = Logger::DEBUG

plus = Google::Apis::PlusV1::PlusService.new
activities = plus.list_activities('103354693083460731603', 'public')

The output of this code should include debug info:

D, [2015-06-26T14:33:42.583914 #12144] DEBUG -- : Sending HTTP get https://www.googleapis.com/plus/v1/people/103354693083460731603/activities/public?key=...
