"Performance Management on a Shoestring Budget" by Jon Poland, Sun Microsystems

Every systems administrator dreads the day when the user calls asking what has happened to the system and why is the application running so slowly. In this presentation, Jon Poland will show us what commands are already on our system to be able to be armed and ready for this phone call.

He will also discuss what are the most likely bottlenecks in a UNIX computer, how they interact, and how to monitor them.

Jon will present an awk program which drives gnuplot. The output provides clear, graphical descriptions of how your system is really performing.

Jon Poland is a UNIX guru. He has been known to debug the kernel of production systems in real-time (sometimes without causing a panic). One day before breakfast he wrote a hex disassembler and reassembler as a vi macro in order to fix a bug in an executable. Jon developed his performance management expertise while developing a high performance, replicated, highly available database application at a time when most people were thinking "relational" was a carryover from the 60's. Jon knows how to remove a file named "-rf /". He can speak for hours using only 2 & 3 letter words. Jon never confuses which is the X-client and which is the X-server. Jon's 8 year old son programs in PERL and sed. Jon's current project is to upgrade /bin/csh to /bin/Csh - the "clairvoyant shell": where !+1 is implemented. Jon is employed as a Systems Engineer by Sun Microsystems (at least until management finds out how he really spends his time.) Jon has been a member of SLUUG for nearly 4 years.

ITEC '97 Expo Review

by Dave Mills & Chris Wanta

ITEC97 was an unqualified success! Once again with the help of many volunteers, SLUUG reached out to many potential members, answered questions, and promoted the open systems format.

Dave and I would personally like to thank all the volunteers who 'muscled' the boxes, manned the booth, sold lots of books, and answered numerous questions. A special thanks to Tom Parsons who covered for Dave and I throughout. Everyone was needed and truly appreciated. We made some wonderful contacts for the future.

All of our volunteers were kept busy from start to finish this year. There was an unprecedented volume of traffic continuously flowing into our booth. I don't believe anyone had a minute of boredom. We had quite a call for our books and there were many special offers in conjunction with our various presentations.

Our presentations had the highest observed attendance of all of the presentations. The Linux As An Internet/Intranet Server by Matthew Feldt (Manager of our Linux SIG) had 25 attendees. The JAVA Overview by John Zukowski (O'Reilly author of the JAVA AWT Reference) broke all records with standing (and sitting on the floor) room only and attendance of 52 people. The more targeted JavaBeans presentation (also by John Zukowski) had a very respectable 24 attendees. And the UNIX/NT Interoperability presentation by Robert Watson (SE Digital Equipment) had 23 attendees. The only down side was that the seminar rooms were on the ITEC conference floor, as temporary rooms without ceilings. This made for very poor acoustics, which will be corrected for next year (or else!).

Once again, thank you one and all for your support at ITEC97. Each of you provided a key element in our team.

Chris Wanta and Dave Mills
