REST API for Monitoring

The RESTful interface is not only used for data management, but as well can be the source for a monitoring infrastructure. We will share our ideas on monitoring via the new RESTful interface and we will demonstrate the currently available functionality.

Convener: Mr Albert Rossi (FERMIlab)

slides al-RESTful2018(1).pptx

dCache view

During last years workshop we introduced dCache-view, the component utilising the RESTful API to generate web pages for graphically uploading and downloading files and to manipulate their quality of service. This year we will elaborate on extended functionalities of that tool and on an enhanced look-and-feel.

Convener: Mr Olufemi Segun Adeyemi

Macaroons

With the increasing availability of automated computing platforms (PaaS) and scientific portals, allowing scientists to focus on their scientific work instead of forcing them to become an IT expert, storage systems are no longer directly accessed by processes under the control of the user but, instead, by a chain of intermediate agents. Consequently, when it comes to authorisation, the resource owner might have to grant permissions, on behave of the user, with narrowing privileges, along that chain. To enable infrastructures to tackle this issue, dCache is implementing Macaroons, a distributed authorisation method, introduced by Google. We will provide examples on how Macaroons have been integrated into dCache and how they can be used in complex computing and storage infrastructures.

Convener: Dr Paul Millar (DESY)
