[Users] centralized Logging engine and hypervisor

[Sven Kieske]

Thanks for the heads up.

Honestly, I think it should be easy
to change logging from file-based to a central
syslog server, but it does not seem to be the case
for oVirt.



Does someone know how to rewrite this section from

/usr/share/ovirt-engine/services/ovirt-engine/ovirt-engine.xml.in

to use syslog?

    <subsystem xmlns="urn:jboss:domain:logging:1.1">

      <!-- All the application server messages go here: -->
      <file-handler name="SERVER">
        <level name="INFO"/>
        <formatter>
          <pattern-formatter pattern="%d %-5p [%c] (%t) %s%E%n"/>
        </formatter>
        <file path="$getstring('ENGINE_LOG')/server.log"/>
        <append value="true"/>
      </file-handler>
