EventLogging/OperationalSupport

Intro
The goal of this page is to describe the operational support the Analytics team provides for Event Logging.

Tier 2 Support
We consider event logging a tier-2 system. An informal definition for a tier-2 system is one that helps you to operate better. A tier-1 system helps you operate, meaning that without it you cannot function. We believe Event Logging is tier-2 as it is used for data that help us improve our applications but we can certainly function without it.

Being tier-2 means that we provide support for Event Logging during business hours in the absence of any tier-1 issue that might be affecting our infrastructure. Event Logging could go down and be down for 48 hours, so you should be sure your reporting can deal with gaps in the data.

Any outages that affect Event Logging will be notified to the list: eventlogging-alerts@lists.wikimedia.org
