Very Computer

I'm new at Linux and I've been trying to figure out a certain command.
I use a solaris box at work and to see process utilization I use a
command called 'SAR'.  Anybody know what the equivalent command would be
for Linux?? I'm using Slackware.

Any info would be much appreciated,
Chris

You can get some of the information from programs like top or vmstat.

I don't think, it's what Christopher is looking for.
the ps or top commands are not quite the same.

Sar is a very useful utility found on SUN, AIX, IRIX, etc... used
to collect statistics over a period of time.

Unfortunately, I'm not aware of a similar utility on Slackware but
one can achieve something similar using ps but this requires
a bit of shell programming.

But I'm almost sure that a similar tool is available at www.linux.org.

sar is not in any Linux distribution as far as I know,however
I once had a tool called atsar (which was build by at-computing ) which is
very good.
And they have a Linux port.. I Have to dig up the sources to check if
it is freely distributable or not (Maybe  you can check their ftp site?)

(I can't look at the moment as I have temporarely only uucp connectivity
to the Internet :-( )

        Not quite!
        I remember "sar" command of some UNIX boxes. I guess it's a
legacy from very old process auditing tools. Linux has no SAR command,
but what SAR used to do is nothing like "ps -aux". The PS command only
shows current process status. SAR gave a statistics of most frequently
used programs, including CPU and memory usage, as well as number of
invocations.

The closest equivalent of sar is the vmstat command.

'sar' is a standard AT&T UNIX command for 'System Activity Reporting'.

It actually comprises a few scripts, 'sa1' that collects the kernel
counters and saves them to a binary logfile, 'sa2' that generates reports,
and 'sar' itself (which is an executable) that lets you interrogate the logs.

There is no Linux equivalent unfortunately.

It's a glaring omission from Linux, and hopefully someone will write an
equivalent soon :-)  It'll need a lot of /proc processing, and isn't as simple
as it sounds.
