DTrace hooks for CPU caps

...s, The CPU caps project (http://www.opensolaris.org/os/project/rm/rctls/cpu-caps/) introduces kernel "wait queues" where threads may be placed to enforce caps. I would like to make this visible through DTrace and to add two new probes to the sched provider with the following semantics: cpucaps-sleep Probe that fires immediately before the current thread is placed on a wait queue. The lwpsinfo_t of the waiting thread is pointed to by args[0]. The psinfo_t of the process containing the waiting thread is pointed to by args[1]. cpucaps-wakeup Probe that fires immediately after a thre...

how to combine grouped data and ungrouped data in a trellis xyplot

...g it to generate charts, but I am still scaling the learning curve in a number of ways. I am looking plot one grouped line and one ungrouped line in a lattice plot. I can plot one grouped line like this (the line's color in each panel becomes dependent on the newpool value): xyp<-xyplot(cpucap~date|zone,data=df,type="l",groups=newpool,auto.key=list(points=F,lines=T), main=paste(df$server[1]," CPU Caps\n",df$date[1]," to ",df$date[nrow(df)],sep="") ) print(xyp) and I can plot two ungrouped lines using a panel=function with subsc...
