Nowadays, IT departments provide, and people use many
various computing services of more and more heterogeneous
nature. And there is a growing need of having a common
display that groups these different services and reports
about their status and availabilities in a uniform way. At
CERN, it led to launching the SLS project.
Service Level Status Overview (SLS) is a web-based tool that
dynamically shows availability, basic information and
statistics about various IT services, as well as
dependencies between them.
The presentation starts with a short description of the
project, its goals, architecture, and users. Then, the
concepts of subservices, metaservices, dependencies, service
availability etc. are introduced, followed by a
demonstration of the system and an explanation of how to add
a service to SLS. The talk ends with a information on how
SLS could be used by other HEP institutes.
