WP7 Middleware Status and Plans Paul Mealor
Contents • GridFTP monitoring • Network monitoring information in RGMA • UK network monitoring
GridFTP • Absolutely definitely will be in EDG 2 • Appropriate code for info-providers (and bug fixes for gsiwuftpd) in RPMs and declared to be released with next EDG • Configuration details declared (inc. LCFG .h files, even though LCFG will change) • Oh, and it’s running at UCL
RGMA ∩ GridFTP • Obviously should do • We’ve got a schema for it, at least
R-GMA • Discussions between WP3 and WP7 some time ago • Decided on schemata for publishing the network performance metrics measured by WP7 • RTT, packet loss (1- and 2-way), IPDV, throughput (TCP & UDP), file-transfer throughput • Also, information to link the SE and CE to a network monitor
R-GMA • Modified the three main WP7 tools to publish into RGMA • PingER: RTT & ICMP packet loss • IperfER: TCP throughput • UDPMon: UDP thoughput & 1-way IPDV • Maintain old web interface, so MDS information providers still work
Here be dragons R-GMA Network monitor Some machine measurements PingER Tomcat: Producer servlets edg-netmon2rgmad Producer API NetworkCE NetworkSE edg-netmon-rgma-infod Notify via FIFO
R-GMA • Advantages • Push model all the way • APIs on NM are lightweight • Tomcat can go somewhere else • edg-netmon2rgmad keeps Producers persistent
R-GMA • This is really running at UCL (installed from RPM, simply configured) • Often (but not now) makes NM data available via the WP3 registry • RGMA-capable network cost function under construction • Robert Harakaly
UK network monitoring • To get network monitoring available in the UK • WP7 tools repackaged in a single RPM • By Gareth Fairey • And Mark Leese • Another map with green dots on it • http://rtlin1.dl.ac.uk/gridmon/
