Data fields

Data fields Process description
PID The process ID
 
PPID The parent PID. Only shown when the -F option is used.
 
User The username
 
%CPU
 
The percent of the CPUs the process is currently (more or less) using.
 
RSS
 
Resident Set Size –Physical memory used by the process; includes shared memory. When the -F flag is used, this value is in kilobytes, otherwise it is displayed in a compact format using four columns. The suffixes K, M, and G are decimal; that is, K means x1000, M x1000000, and G x1000000000.
 
VSZ
 
Virtual memory used by process. The format is the same as described above.
 
UsrTim
 
This is the user-mode CPU time being consumed by the process. This has two modes, depending on whether the -ot command option was specified. In the default mode, the value is a normalized delta; that is, how much user time has been consumed since the last sample, normalized over 1 second. If -ot was specified, the value is the absolute amount of user time the process has accumulated since it started, in the form Minutes:Seconds.
 
SysTim
 
The CPU time in kernel-mode being consumed by the process (see the description of UsrTim above).
 
Pri
 
The UNIX priority of the process. This is only shown when the -F option is used.
 
IBk
 
Input Block Operations –Actual file system blocks read or written
 
OBk
 
Output Block Operations
 
Maj
 
Major faults –– Faults that were satisfied by doing I/O (going to disk).
 
Min
 
Minor faults –Faults that were satisfied from cache.
 
Command
 
Note that arguments specified when the program was invoked are not retrieved.
 

Disks

DSK
 
This is an index into the table that Collect outputs; used for scripting.
 
NAME
 
The name of the device, specified as dskinstance such as dsk23 and found in the system’s /dev directory.
 
B/T/L
 
If this is a SCSI disk it contains the Bus/Target/Lun identifier, otherwise a dash (–). The hwmgr command can also be used to find devices. See the hwmgr(8) reference page for information on the command options.
 
R/S
 
Reads per second
 
RKB/S
 
Kilobytes read per second
 
W/S
 
Writes per second
 
WKB/S
 
Kilobytes written per second
 
AVS
 
Average service time; time spent actually servicing the request –no wait time (in milliseconds).
 
AVW
 
Average wait time; time spent in the wait queue (in milliseconds)
 
ACTQ
 
The number of requests in the active queue (that is, being serviced by the disk)
 
WTQ
 
The number of requests in the wait queue (have not yet been submitted to disk)
 
%BSY
 
Percent Busy –Time spent servicing requests in interval divided by interval.
 
%WT
 
Percent Wait –Time spent waiting in interval divided by interval.
 

Tapes

NUM
 
An index for scripting
 
NAME
 
The device name, tape instance, where instance is an integer in the range 0–256 and can be found in the /dev/tape directory. The hwmgr command can also be used to find devices. See the hwmgr(8) reference page for information on the command options.
 
B/T/L
 
The Bus/Target/Lun IDs (identifiers)
 
R/S
 
Reads per second
 
RKB/S
 
Kilobytes read per second
 
W/S
 
Writes per second
 
WKB/S
 
Kilobytes written per second
 

LSM volumes

VOL
 
An index for scripting
 
NAME
 
Name in the form "Diskgroup/Volume" to ensure uniqueness
 
R/S
 
Reads per second
 
RKB/S
 
Kilobytes read per second
 
RAVS
 
Average service time for reads with respect to LSM driver (includes disk driver wait time)
 
W/S
 
Writes per second
 
WKB/S
 
Kilobytes written per second
 
WAVS
 
Average service time for writes with respect to LSM driver (includes disk driver wait time)
 

CPU summary

USER...WAIT
 
CPU states, averaged over all CPUs
 
INTR
 
Interrupts per second
 
SYSC
 
System calls per second
 
CS
 
Context switches per second
 
RUNQ
 
Number of processes in the run queue
 
AVG5,30,60
 
Load average over the last 5, 30, and 60 seconds
 
FORK
 
Number of forks/second
 
VFORK
 
Number of vforks/second
