processor info 6 months ago

I need to do some detective work!

I know that you can see how many processors a linux machine has by running the command "less /proc/cpuinfo | grep processor".
Is there anyway to see how many processors a machine had at some point in the past?  E.g. an archived cpuinfo file or anything like that?

The machine in question is running Red Hat Enterprise Server 3.0 BTW.

Many thanks

Hi,

I can only see four versions of this file.  Only the most recent has any information.  The rest just tell you that the system was rebooted.

The files that you see are the logs as left by the log daemon - It swaps around logs and deletes old ones, so if you wand to look at further back than the dates of the logs, then you cannot do it.

However, what might be useful to you is dedermining whether the system has changed from being a single CPU to a SMP (multiple cpu)?

You may be able to glean some information relating to this by looking at the files in /boot and looking at the dates on the files there. SMP files will probably have SMP in their name?

If you have good backups you can restore old /var/log/messages files...

You may try to grep root mail for periodic kernel log messages, like:

grep -i processor /var/spool/mail/root

Thanks for trying guy's but unfortunately none of these suggestions have helped me.
I don't think I will be able to get the information I am looking for.
