Hi,
Does anyone know how to check which process has been used the most CPU between certain time period?
say I have noticed CPU spike happend between 1:00 to 1:30
now it is 3:00 o'clock already. Is there anyway to find out what process/PID use the most CPU then?
Thanks a lot (3 Replies)

Hello Friends,
On one of my Solaris 10 box, CPU usage shows 100% using "sar", "vmstat". However, it has 4 CPUs and prstat and glance are not showing enough processes to justify high CPU utilization.

I'm running on Solaris 10, and I have a script that's running on several machines. Basically, what it's doing is:

* Sed through the 2nd temp to pull out a user... (2 Replies)

scsi_arq_status
scsi_arq_status(9S) Data Structures for Drivers scsi_arq_status(9S)
NAME
scsi_arq_status - SCSI auto request sense structure
SYNOPSIS
#include <sys/scsi/scsi.h>
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI)
DESCRIPTION
When auto request sense has been enabled using scsi_ifsetcap(9F) and the "auto-rqsense" capability, the target driver must allocate a sta-
tus area in the SCSI packet structure for the auto request sense structure (see scsi_pkt(9S)). In the event of a check condition, the
transport layer automatically executes a request sense command. This check ensures that the request sense information does not get lost.
The auto request sense structure supplies the SCSI status of the original command, the transport information pertaining to the request
sense command, and the request sense data.
STRUCTURE MEMBERS
struct scsi_status sts_status; /* SCSI status */
struct scsi_status sts_rqpkt_status; /* SCSI status of
request sense cmd */
uchar_t sts_rqpkt_reason; /* reason completion */
uchar_t sts_rqpkt_resid; /* residue */
uint_t sts_rqpkt_state; /* state of command */
uint_t sts_rqpkt_statistics; /* statistics */
struct scsi_extended_sense sts_sensedata; /* actual sense data */
sts_status is the SCSI status of the original command. If the status indicates a check condition, the transport layer might have performed
an auto request sense command.
sts_rqpkt_status is the SCSI status of the request sense command. sts_rqpkt_reason is the completion reason of the request sense command.
If the reason is not CMD_CMPLT, then the request sense command did not complete normally.
sts_rqpkt_resid is the residual count of the data transfer and indicates the number of data bytes that have not been transferred. The auto
request sense command requests SENSE_LENGTH bytes.
sts_rqpkt_state has bit positions representing the five most important statuses that a SCSI command can go obtain.
sts_rqpkt_statistics maintains transport-related statistics of the request sense command.
sts_sensedata contains the actual sense data if the request sense command completed normally.
