Does anyone have any hard numbers on the performance impact on system
accounting?
I have always assumed that there is a significant performance impact on
the system when full
accounting is turned on. Any takers?

Depends on what you consider "significant", I'm afraid. One hard numberQuote:>Does anyone have any hard numbers on the performance impact on system

On a RS/6000, continuous sar polling with the SARLED utility (display
system availability on the 3-digit LED) at 1 poll/second eats 10% system
time on a RS/6000 model 320.

1. Easy way to identify system created account or account for system services
Hi,
I'm compiling unix & linux account list in my company under linux 6.2,
7.0 & digital unix 4 platforms (I'm not the original administrator of
these servers & no document left behind by previous adminstrator who
had left).
As I cat the /etc/passwd file, I found many accounts seem be used by
OS or system services only. Some of them are very obvious like adm,
bin, daemon, lp, news, uucp, games, gopher, ftp, sys, etc. But each
platform has some unique account names which seem not being used by
users e.g. gdm, halt, nobody, nobodyV, nobody4, tcb, ris, wnn, nuucp,
etc.
I would like to ask is there any easy way to identify which account is
human user account and which being OS / OS service accounts ? Any
document available on internet to list those common system services
accounts ?
Can I based on the initial program or shell that executes to help
judge this e.g. user accounts will initialize a shell like bash, csh,
etc while system own accounts will not.
Tks!
