GridPP storage availability monitoring
The graphs below show the status of storage resources as reported by SAM for GridPP sites supporting the ops VO. The system looks at the SE and SRM tests and adds up how many times each test passed and how many times it failed each day. The script then calculates the percentage that passed for each day. The greener the square, the higher the pass rate.
I do not take CE tests into account, so the percentages reported below are slightly different to those from Steve Lloyd's tests.
Those of you in CMS might recognise the style of the plots.
Thanks to Brian Bockleman for the scripts used to generate these plots using GraphTool from CMS.
