Re: Does redhat linux log all hardware events/issues/error in /var/log/mcelog?

Hi,

We run redhat linux on intel hardware (mostly Dell, lately dell R710s).
We want to be able to catch any hardware issues when they occur to act on
them as quickly as possible.

My understanding is that all hardware events/issues/errors are logged in
/var/log/mcelog (Machine Check Events log). Is this correct? Can't stress
this enough; does it log all hardware issues
(cpu,memory,disk,ethernet,fibre/hba etc) ?

Thanks,

I've used MCElog to catch some CPU events but I think you might want to check out Dell's OpenManage client. It will report/monitor a lot more information.
