Hi,

I made some progress in porting 2 data recorders to FreeBSD:
cpurec, hdwrec: http://www.systemdatarecorder.org/recording/agents.html

Im working now on sysrec and found very powerful the sysctl interface since last
time I checked in 2007 or so. 

But I could not find any way to get the value of run-queue length via sysctl.

 procs      memory      page                    disks     faults         cpu
 r b w     avm    fre   flt  re  pi  po    fr  sr mf0 mf1   in   sy   cs us sy id
 0 0 0    757M    61G     6   0   0   0    12   1   0   0    9   50  135  0  0 100

 0 0 0    757M    61G     0   0   0   0     0   1   0   0    4  125   99  0  0 100

I dont want to call vmstat in my script ... Any ideas how to do this ?

thanks,
