Re: What commands needed to sanity check and performance eval a linux box?
I can also suggest you use stress and leave it running for an entire day.
http://weather.ou.edu/~apw/projects/stress/
(Use google to look for rpms if you are lazy to compile it from source)
Another option would be to use StressLinux
http://www.stresslinux.org/sl/
From their homepage:
What is stresslinux ?
stresslinux is a minimal linux distribution running from a bootable cdrom, usb, vmware or via PXE (wip).
stresslinux makes use of some utitlities available on the net like: stress, cpuburn, hddtemp, lm_sensors ...
stresslinux is dedicated to users who want to test their system(s) entirely on high load and monitoring the health.

Re: What commands needed to sanity check and performance eval a linux box?
Or am I missing something?
Question: Why don't other Linux Admins use /proc to eval linux?

Re: What commands needed to sanity check and performance eval a linux box?
For example, sar output can be easily plotted to a chart with excel or other tools and quickly discover any trends.

Re: What commands needed to sanity check and performance eval a linux box?
I think sar is a great way to go.
For years I've been meaning to port http://hpux.ws/system.perf.sh to Linux.
That is where I'd start.
I'd also consider hobbit monitoring or Openview.

Re: What commands needed to sanity check and performance eval a linux box?
On a UNIX-away path too eh? Yeppers -- the new Nehalems and Magny Cours X86-64 systems are just awesome and can compete with the UNIX big irons.
But I digress... as a UNIX person who's also crossing to the Penguin side (at work -- been using at for "magny" years now at home and NGOs/small-biz shops) -- most of the UNIX tools you've been accustomed to are available on LINUX ... there are also tons of OSS (open source tools) available out on the internet wild...
You can be at home rather quicly man... and most stuff are actually simpler and easier on Linux.

Re: What commands needed to sanity check and performance eval a linux box?
I guess I'm old fashioned. Using applications with embedded command line operations isn't being a sys admin. Its something a lot less.

Re: What commands needed to sanity check and performance eval a linux box?
If you manage HP-UX systems (or other UNIX Flavours) -- the tools you've been accustomed be SHOULD be available "including" the commercial one$ -- you know, OVPA/Insight/GlancePlus, Director (hmm thats Blue), Patrol/BMC, CA...etceterum.
IF it is a DB machine... then for "sanity/performance" checks/tests -- I always go with:
- IOZONE for I/O
- ORION (an Oracle Tool) for simulating DB I/O Load (and characterisation)
- and finally SwingBench
