The data operation centre tool. Architecture and population strategies
2012
Keeping track of the layout of the informatic resources in a big datacenter is a complex task. DOCET is a database–based webtool designed and implemented at INFN. It aims at providing a uniform interface to manage and retrieve needed information about one or more datacenter, such as available hardware, software and their status. Having a suitable application is however useless until most of the information about the centre are not inserted in the DOCET'S database. Manually inserting all the information from scratch is an unfeasible task. After describing DOCET'S high level architecture, its main features and current development track, we present and discuss the work done to populate the DOCET database for the INFN-T1 site by retrieving information from a heterogenous variety of authoritative sources, such as DNS, DHCP, Quattor host profiles, etc. We then describe the work being done to integrate DOCET with some common management operation, such as adding a newly installed host to DHCP and DNS, or creating a suitable Quattor profile template for it.
