Yes, sorry. I guess proof this is a hobby on some personal hosting that can get overloaded. Try refreshing. Although it's load averages (couldn't resist) aren't that high:
And yes I'd noticed on many *nx systems that it didn't seem to be pure CPU (I think I once had a single-CPU SunOS 4.1.1 NFS server report into the tens or hundreds because disc was slow) I've mainly been treating it as if CPU for ~30Y. Goodness knows what I might have tuned better!
Just because we can deploy services that can take a million RPS doesn't mean we have our side projects / hobby sites in order, hah. I worked in hosting for a long time and I had a personal WordPress site which would get hacked every other month. I literally fixed that problem daily at $JOB, but couldn't be arsed to do something better for myself. It worked, and it was quick and easy. The point was the content.
These days, I'd just use something like Medium or Tumblr. Let someone else worry about hosting it :)
I still managed to read the whole thing. Quite fascinating, really, considering the lengths he went into tracking the ancient (1993) patch that turned CPU load averages into whole system load averages.
I am beginning to suspect that Brendan Gregg is not a real person, but a collection of extremely talented individuals publishing under a pseudonym. ( https://en.wikipedia.org/wiki/Nicolas_Bourbaki )
PS: yes this is meant to be a compliment on the prolific output on performance related topics that Greg puts up on his page.
I wonder what a what a good solution for aggregating all of this data and making it more easily searchable next time would look like, and if there's anyone working on it.
It seems like such a waste to have it scattered all over the place, and for all the author's hard work in tracking it down to go to waste.
