MACHINE CHECK EXCPETION NOTIFICATION VIA EMAIL
==============================================

(C)opyright by Thomas Renninger <trenn@suse.de> Novell Inc. 2010

The setup to send Machine Check Exceptions (MCEs) via email relies on a
working smtp server listening on localhost on port 25.

How this can easily be configured is can be read up here:
http://en.opensuse.org/Mail_server_HOWTO
in the "Outgoing" section.

Test your setup by trying to send test mails via the "mail" shell command,
included in the mailx package.

Specify the email address where the MCEs should get mailed to here:
/etc/sysconfig/mcelog

You can filter MCE mails by matching against these mail headers.
Either one of these headers are set:
  - X-Mcelog-Uncorrectable
  - X-Mcelog-Correctable

and one of these are set:
  - X-Mcelog-Memory
  - X-Mcelog-CPU
  - X-Mcelog-Misc

NOTE: If broken HW results in an MCE storm of dozens and hundreds of MCEs,
mcelog will not sending them all to not overload the machine and network
traffic. If in doubt, check the local mcelog log files.

Autoyast
--------

For people making use of autoyast to spread similar installations on multiple
machines, here are some hints how to set up the email notification through
autoyast. Please read the autoyast documentation first if you are not familiar
with how to create an autoyast.xml file.

This simply sets the email address, notifications should get send to:

<sysconfig config:type="list">
    <sysconfig_entry>
      <sysconfig_key>MCELOG_ADMIN_EMAIL</sysconfig_key>
      <sysconfig_path>/etc/sysconfig/mcelog</sysconfig_path>
      <sysconfig_value>trenn@suse.de</sysconfig_value>
    </sysconfig_entry>
 </sysconfig>

This is an example of how to set up postfix to listen on localhost and
sending/forwarding all mails coming in there through the smtp server
relay.suse.de.
The alias at the beginning forwards local machine notifications sent to root,
to trenn@suse.de. Like that mails interesting for the administrator can easily
be collected and sent to one email address. But this is just one possible mail
set up example.

<mail>
    <aliases config:type="list">
      <alias>
        <alias>root</alias>
        <destinations>trenn@suse.de</destinations>
      </alias>
    </aliases>
    <connection_type config:type="symbol">permanent</connection_type>
    <listen_remote config:type="boolean">false</listen_remote>
    <masquerade_other_domains config:type="list">
      <domain>suse.de</domain>
    </masquerade_other_domains>
    <mta config:type="symbol">postfix</mta>
    <outgoing_mail_server>relay.suse.de</outgoing_mail_server>
    <postfix_mda config:type="symbol">local</postfix_mda>
    <use_amavis config:type="boolean">false</use_amavis>
</mail>
