Question about pmcstat

[rainer at ultra-secure.de]

Hi,

in Brendan Gregg's tutorial:

http://www.brendangregg.com/blog/2015-03-10/freebsd-flame-graphs.html

it says to run

pmcstat –S RESOURCE_STALLS.ANY -O out.pmcstat sleep 10

However, I get

freebsd11 </root>) 0 # pmcstat –S RESOURCE_STALLS.ANY -O out.pmcstat 
sleep 10
pmcstat: [options] [commandline]
          Measure process and/or system performance using hardware
          performance monitoring counters.
          Options include:
          -C              (toggle) show cumulative counts
          -D path         create profiles in directory "path"
          -E              (toggle) show counts at process exit
          -F file         write a system-wide callgraph (Kcachegrind 
format) to "file"
          -G file         write a system-wide callgraph to "file"
          -M file         print executable/gmon file map to "file"
          -N              (toggle) capture callchains
          -O file         send log output to "file"
          -P spec         allocate a process-private sampling PMC
          -R file         read events from "file"
          -S spec         allocate a system-wide sampling PMC
          -T              start in top mode
          -W              (toggle) show counts per context switch
          -a file         print sampled PCs and callgraph to "file"
          -c cpu-list     set cpus for subsequent system-wide PMCs
          -d              (toggle) track descendants
          -e              use wide history counter for gprof(1) output
          -f spec         pass "spec" to as plugin option
          -g              produce gprof(1) compatible profiles
          -k dir          set the path to the kernel
          -l secs         set duration time
          -m file         print sampled PCs to "file"
          -n rate         set sampling rate
          -o file         send print output to "file"
          -p spec         allocate a process-private counting PMC
          -q              suppress verbosity
          -r fsroot       specify FS root directory
          -s spec         allocate a system-wide counting PMC
          -t process-spec attach to running processes matching 
"process-spec"
          -v              increase verbosity
          -w secs         set printing time interval
          -z depth        limit callchain display depth


I assume, the event specifier is not correct. Is there a list of the 
valid ones in FreeBSD 11?


What am I missing?
