architecture
moved to Apache on linux underlying GridPort updated to 2.3 object-oriented perl module packaging simplified installation new features: NWS, etc. HotPage updates
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
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
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
queue 87 GP-IR data example
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
resource view sorting
summary table grid monitor NWS grid view
historical performance queries portlets - presentation this week customization, portability GridPort ditto OGSA HotPage source code distribution - this week? rollout technologies to PACI HotPage NPACI, NCSA and PSC resources to do
