Hi All,
I am working on a Solaris machine. When i use a particular software to generate some files, the log shows around 0 to 3 secs for generating each file. But the same when i see on the disk it shows double the time difference between two file generation.
For example if file A takes 0 secs... (7 Replies)
I've been asked to gather CPU, memory and disk stats in the following format:

Can anyone please tell me a command to gather all this info?
Thanks!

acct
ACCT(5) BSD File Formats Manual ACCT(5)NAME
acct -- execution accounting file
SYNOPSIS
#include <sys/acct.h>
DESCRIPTION
The kernel maintains the following acct information structure for all processes. If a process terminates, and accounting is enabled, the ker-
nel calls the acct(2) function call to prepare and append the record to the accounting file.
/*
* Accounting structures; these use a comp_t type which is a 3 bits base 8
* exponent, 13 bit fraction ``floating point'' number. Units are 1/AHZ
* seconds.
*/
typedef u_short comp_t;
struct acct {
char ac_comm[10]; /* name of command */
comp_t ac_utime; /* user time */
comp_t ac_stime; /* system time */
comp_t ac_etime; /* elapsed time */
time_t ac_btime; /* starting time */
uid_t ac_uid; /* user id */
gid_t ac_gid; /* group id */
short ac_mem; /* memory usage average */
comp_t ac_io; /* count of IO blocks */
dev_t ac_tty; /* controlling tty */
#define AFORK 0x01 /* forked but not execed */
#define ASU 0x02 /* used super-user permissions */
#define ACOMPAT 0x04 /* used compatibility mode */
#define ACORE 0x08 /* dumped core */
#define AXSIG 0x10 /* killed by a signal */
char ac_flag; /* accounting flags */
};
/*
* 1/AHZ is the granularity of the data encoded in the comp_t fields.
* This is not necessarily equal to hz.
*/
#define AHZ 64
#ifdef KERNEL
struct vnode *acctp;
#endif
If a terminated process was created by an execve(2), the name of the executed file (at most ten characters of it) is saved in the field
ac_comm and its status is saved by setting one of more of the following flags in ac_flag: AFORK, ASU, ACOMPAT, ACORE and ASIG.

A acct file format appeared in Version 7 AT&T UNIX.
