It would be great to be able to send logs to a centralized log manager such as Graylog2. For this particular log manager, there is already a gem to handle the Graylog Extended Log Format (aka. GELF) : https://github.com/Graylog2/gelf-rb.
Agree. We have been testing out VMWare Log Insight and Splunk. A great feature in the product would be a Logging admin interface with the top log management platforms already setup. Admin just selects the one they are using and inputs the appropriate information.
