7. status bar

8. individual resource info

9. login for more tools

10. architecture

11. moved to Apache on linux underlying GridPort updated to 2.3 object-oriented perl module packaging simplified installation new features: NWS, etc. HotPage updates

12. old methods of data collection: cron jobs on webserver, triggering ssh commands to execute remote scripts on resources and store data on webserver Globus job run to execute remote scripts GIS queries for status data data collection

13. problems with old methods: some scripts generated LDIF, some HTML no separation of content and presentation GIS support inconsistent across partner sites no persistent storage of data - historical record data collection

14. GridPort Information Repository developed at TACC, with help from SDSC XML-centric database to store performance and other data web services data ingester and query interface GP-IR data repository

16. queue 87 GP-IR data example

17. cron jobs run on HotPage server to query GP-IR every five minutes and write out xml to cache directories HotPage page requests generate live queries to GP-IR if live queries fail, HotPage scripts load cached XML GP-IR data caching

18. resource view sorting

19. summary table grid monitor NWS grid view

20. historical performance queries portlets - presentation this week customization, portability GridPort 3.0 - ditto OGSA HotPage source code distribution - this week? rollout technologies to PACI HotPage NPACI, NCSA and PSC resources to do
