Mandate

The mandate is the following:

  • Define the minimum set of useful functions which must work for a site to "support HTTP for WLCG". Document what further functionality is desirable over HTTP, under what circumstances, and with what priority.
  • Put in place the necessary monitoring and validation tools.
  • Summarise advice for sites on deployment. Create baseline version information for the storage systems. Identify necessary changes to supporting services.
  • Track and support the deployment on the infrastructure until the point where maintenance is transferred to standard experiment operations.

The TF motivation and initial suggestion for the mandate was presented at the Ops coordination meeting on 19th Feb.

Desired functionality for HTTP storage

The TF has created a table of required and desired functionality for HTTP storage, available on a dedicated page.

A more detailed discussion of these requirements is being summaries in a document detailing recommendations and priorities for storage provides and maintainers of monitoring probes. This document is being assembled under HTTPTFStorageRecommendations.

Information for Sites

If you are a site administrator and have been contacted by the TF (or want to know more), please take a look at our Information for Sites.

SAM/Nagios Probe

The TF is developing a shared SAM/Nagios probe to use in validation of HTTP storage. Here you can find the relevant documentation.

TF Process for ticketing and supporting sites

The TF will use the probe results to contact sites and help them pass the validation. Here is the process.
