JPTree

JPTree is a tabular display of running processes, displayed as a tree to display the relationship between processes. Selecting a process displays some of its properties.

• TIME: cpu time accumulated by the process
• TASK: process taskid
• PROJ: process project id
• ZONE: id of the zone the process is running in
• CT: process contract id (see smf)

The thread usage fields displayed are:

• LWP: the lwp id
• RTIME: elapsed time used by the lwp
• UTIME: user time
• STIME: system time
• MAJF: major faults incurred by the lwp
• INBLK: blocks input by this lwp
• OUBLK: blocks output by this lwp

• VCTX: voluntary context switches incurred by the lwp
• ICTX: involuntary context switches incurred by the lwp

The rows can be sorted by selecting the column header.
