The Linux Performance Monitoring Course teaches systems administrators practical methodologies for monitoring systems using standard system tools. The course breaks performance into 4 functional components: CPU, Memory, I/O, and Network. The instructor will cover 4 aspects of each component:

1) Component Architecture from a System Administrator Perspective (not developer)

2) How to interpret and correlate the output from standard system tools to identify issues

3) Any relevant tuning options available to the component

4) Case study – demonstrating how to use monitoring skills

Very detailed, useful, and delivered effectively. The scenario-based information was very accessible and pertinent to the every-day concerns of someone who administers heavily loaded servers. Specific, actionable, detailed information. In fact, the very next day I was using some of the same commands to poke around my own servers.

Akkana makes a good point: Throwing some bold-faced text into the screen dumps would have been helpful.

Great stuff! Unexpectedly informational – I thought I knew it all but this talk (and take home materials) contained lots of good tips/tricks and tools which I will implement right away.

Over the top excellent! Very dense with details (a good thing). Questions were clearly answered. The take home paper was well written.

Visual highlights would be good, as others have reported.

Excellent tutorial—packed with useful information yet still easy to follow. The case studies helped a lot and the handout will be a great reference.

Only suggestion: highlight important fields on screen—sometimes it was hard to follow the laser pointer (or even see it from the back of the room).

Overall, an extremely well done presentation – packed a lot of information in, a lot of good examples and really exceeded my expectations. I can see why Darren is asked to come back each year. My only (minor) complaints are:

a) that it would have been more helpful in the sections where iostat, mpstat or other terminal output was shown, to have arrows pointing to areas of interest, e.g. the wa column if a system was IO bound and the CPU was waiting on output, etc., b) although demos have potential to fail and mess up a presentation, it would be helpful to have it in some way, perhaps in a video that could be paused as needed during the presentation.

But again, these are relatively minor – on the whole, a really great presentation.

Well-done. I’ve been a sysadmin for 15 years and I definitely leaned some new things, along with learning why things I’d learned through trial and error are so.

Great stuff: good balance of theory (kernel algorithms), and how the tools show what the kernel is trying to do. More info on app server perf issues would help (but maybe presenter doesn’t see enough of these kind of problems.)
