20080117: Technical Statistics: What they tell us, and what they don't
- 1. Technical Statistics What they tell us, and what they don’t Ian A.Young, SDSS London, 17th Jan 2008
- 2. Sources • Federation web site logs • Metadata download logs • WAYF access logs • Membership statistics • Metadata statistics 2

- 4. Federation Web Site • We’re seeing about 1500 page views per day at present: significant use • That has been pretty stable for 11 months, although federation itself has grown • Perhaps people use the site when they’re joining, but not afterwards? 4
- 5. Membership Just SP 9% Just IdP IdP + SP 22% 15% Gateway 5% Membership alone 49% Data 11-Jan-2007 5
- 6. Membership • Many members have both IdP and SP entities • may be for testing or for collaboration • Half of members have no participation • Good awareness, bad deployment? • Planning on gateway use only? • “Gateway members” beginning to show up 6

- 11. Certificates • JANET SCS being widely used • Significant number of entities offline • Small number of IdPs “just broken” • No way to survey SP trust certificates
- 12. Software Shibboleth Other 96% 4% Data 12-Jan-2007 12
- 13. Software • Shibboleth dominates • Almost all 1.3: only 3×1.2, 2×2.0 • If other software supported large scale federation, more people might use it. • Need to determine how much to let technical holes in other software hold us back
