and rise to the top “mce: [Hardware Error]: Machine check events logged” appears in syslog. What should I do? up vote 7 down vote favorite 4 I have installed the latest version of OSSEC (2.8.1) and I have also enabled email notifications. And I am getting loads of these sorts of notifications saying that there is a Hardware Error and something about mce: OSSEC HIDS Notification. 2015 Apr [hardware error]: machine check events logged suse 04 20:09:22 Received From: Bath-Towel->/var/log/syslog Rule: 1002 fired (level 2) -> "Unknown problem somewhere in the system." Portion of the log(s): Apr 4 20:09:21 Bath-Towel kernel: [ 1873.680872] mce: [Hardware Error]: Machine check events logged --END OF NOTIFICATION So what exactly does this mean? What does mce stand for? And is this apparent hardware error anything that I should worry about?

The web interface helps as it has a number of explanations - ossec.net/wiki/index.php/OSSECWUI:Install –bodhi.zazen Apr 4 '15 at 19:43 ossec-docs.readthedocs.org/en/latest/faq/… –bodhi.zazen Apr 4 '15 at 19:45 ossec is probably poorly supported or off topic here as it is not in the ubuntu repositories –bodhi.zazen Apr 4 '15 at 19:51 1 This is not about OSSEC at all. You got that notification because OSSEC found the word "error" in syslog. Although I don't think it is off-topic, you'll probably get more help form Unix & Linux or Server Fault. –E

Submit a support ticketWhat are Machine Check Exceptions (or MCE)?Last update: August 18, 2014Categories:Hardware / TroubleshootingIf you are seeing messages in your system logs that state "Machine Check Event logged" this could be an indication of a hardware problem or failure.A machine check exception is an error detected by your system's processor. There are 2 major types of MCE errors, a notice or warning error, and a fatal exception. The warning will be logged by a "Machine Check Event logged" notice in your system logs, and can be later viewed via some Linux utilities. A fatal MCE will cause the machine to stop responding and the details of the MCE will be printed out to the system's console.What causes MCE errors?There most common reason for MCE events to occur are:Memory errors or Error Corr
is an error generated by the CPU when the CPU detects that a hardware error or failure has occurred. Machine check exceptions (MCEs) can occur for a variety of reasons ranging from undesired or out-of-spec voltages from the power supply, from cosmic radiation flipping bits in memory DIMMs or the CPU, or from other miscellaneous faults, including faulty software triggering hardware errors. Contents 1 Installation 2 Configuration 3 See also 3.1 Hardware documentation Installation Install the mcelog package. mcelog written by Andi Kleen is one of the tools to gather MCE information. Configuration mcelog's configuration file is located at /etc/mcelog/mcelog.conf. See man mcelog, man mcelog.conf and man mcelog.triggers for more information. Start and enable mcelog.service. By default, the service runs mcelog as a daemon.
