Is there a command which can tell me whats in the Solaris run queue?
I can get a count using vmstat, but I need to know what processes/threads are in there.

    The run-queue is always changing, so it’s almost impossible to get the set of processes in the current run-queue.

    That said, you can get an approximation by looking at the STAT (state) field of the process list from ps. When running the command below:

    $ ps aux

    …the if the STAT field begins with R, then the process is marked RUNNABLE by the kernel, which on most operating systems means that it is in the run-queue. Here’s what a runnable process looks like on my machine:

    USER       PID %CPU %MEM      VSZ    RSS   TT  STAT STARTED      TIME COMMAND
root     78179   0.0  0.0   599828    480 s003  R+    7:51AM   0:00.00 ps aux

    On solaris, you can also use the prstat command and look at the STATE column. The value run indicates that the process is on the run-queue. (Also note that the value cpuN indicates that the process is currently running on processor N.

    For example:

    $ prstat -s cpu -n 5

PID USERNAME    SIZE    RSS STATE   PRI NICE    TIME    CPU PROCESS/NLWP
