fche: sorry went away earlier
<jameshyde>
hit some strange issue with load average
<jameshyde>
there's no load on the server, everything's idle, no D state procs, but load averge would go very high and stay there forever
<jameshyde>
that's after running turbostat command. Untill I ran some ftrace command, then it would come down by itself.
<jameshyde>
wondering if systemtap could be used to see what's going on

hi there
<izabera>
i'm having a few problems with scripts that used to work and the errors don't seem related to anything in my code
<izabera>
rather something in systemtap
<izabera>
i'm using Systemtap translator/driver (version 3.2/0.170, rpm 3.2-2.fc27)
<izabera>
on an up to date fedora
<fche>
hi izabera
<izabera>
hi
<fche>
what kind of errors? compilation?
<fche>
so the messages advise [man error::pass4] ?
<fche>
periodic fedora kernel rebases require bringing stap more up to date with them; an update went out to the -testing repo just yesterday
<irker552>

<eklitzke>
how do i access a string parameter in a userspace market from systemtap? stap seems to think the argument is a long
slowfranklin has quit [Quit: slowfranklin]
<eklitzke>
nm i figured it out
<eklitzke>
user_string
<fche>
righto
<fche>
pointers come across as 'long'
<fche>
but if you use $ptr$ then stap will heuristically decode char*s to pretty'printed strings
