Welcome to Happyface’s documentation!¶
Happyface is a meta monitoring tool, aimed at WLCG site operators. It is designed to monitor services which are necessary to run a WLCG site. For this, data is aggregated from several sources and stored in a local database. Calculating the status of each service and subsequently generating tables or figures with only the most important information allows for a quick overview of the status of the services. With traffic light colors, the status of each analysis can easily be assessed even by inexperienced shifters at a glance.
