Hi Sven, AFAIK there following logging configuration files in ovirt-engine: 1) /etc/ovirt-engine/notifier/log4j.xml - for ovirt-engine-notifier service 2) /etc/ovirt-engine/engine-manage-domains/log4j.xml - for engine-manage-domains tool 3) /etc/ovirt-engine/engine-config/log4j.xml - for engine-config tool 4) /usr/share/ovirt-engine/services/ovirt-engine/ovirt-engine.xml.in - for ovirt-engine service (webadmin & userportal) 1), 2) and 3) are standard log4j config files. 4) is JBoss deployment configuration which includes logging section.

Well I found some old devel mail regarding this topic:

http://lists.ovirt.org/pipermail/engine-devel/2011-November/000122.html

is there another log4j.xml beside /etc/ovirt-engine/engine-config/log4j.xml ?

I didn't find one which manages the engine.log

Is this hard coded?

I think these tutorials might fit somehow?

for vdsm I'll just have to change:

/etc/vdsm/svdsm.logger.conf and /etc/vdsm/logger.conf

to:

handlers=syslog

Am I on the right track for the engine-log?

Hi and thanks for this reply, I guess this will help me.

I'm going to test it.

Meanwhile I want to ask:

Is this the correct location for an configuration file?

I know it is maybe not intended for "normal" use to tweak this file, but I think it is a configuration file after all and should be under /etc/ like all the others?

(This is why I didn't find it, I was just looking under /etc/ )

Well, probably due to other configuration included in this file, which users shouldn't rather touch. Alon, can you comment?

Hi, and thanks for pointing this out. Maybe my BZ at: https://bugzilla.redhat.com/show_bug.cgi?id=1078738 could suffice as a first subtask in solving this issue by introducing a syslog handler module shipped by ovirt for jboss 7.1 and maybe additionally put another couple of log4j.xml into /etc/ovirt-engine/engine.conf[.d/*.conf] for the purpose of logging. the log4j.xmls are better to edit at least.

Hi,

The jboss service xml is sensitive monolithic block of data as any J2EE resource, to make it complex, the format is XML.

We cannot put it in /etc as every upgrade requires to overwrite the file for product to be usable.

In order to allow some level of customization we inject variable from /etc/ovirt-engine/engine.conf[.d/*.conf] into the content upon service start. As the logging part of this file, and the nature of the syntax is not fixed, I yet not found a decent solution[1].

What I really want to see, is that we can programmatic control what loggers we have and what level to enable and add these into our own configuration, detaching from jboss configuration, and even maybe can modify the log level dynamically at runtime as expected from this scale of application.

I had short discussion about this with Mooli, I hope someone is capable of taking such task.

I have a similar issue, but my Windows clocks are always 4 hours ahead now, as if they were set to UTC. What time zone are you in? I have been under the impression that this is likely due to: https://bugzilla.redhat.com/show_bug.cgi?id=1062615 but haven't tried the fix myself yet (supposed to be fixed in 3.4). -Bob On Thu, Mar 20, 2014 at 10:49 AM, Blaster <blaster@556nato.com> wrote:

Ever since the "Spring Forward" on March 9th, my Windows 7 guests are behind an hour every time they reboot. The Fedora 20 guests are just fine.

I can set the correct time, reboot, comes back up an hour behind. I've tried setting the time zone in the properties to both GMT and to the correct timezone, still the same, behind an hour on reboot.

What am I doing wrong?

And what affect does setting the time zone in the properties supposed to have on the guest?

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>

Don't forget to backup the file, it's not marked as a config, so a new update will replace it :)

$ rpm -q --qf '[%{filenames}: %{fileflags}\n]' -f /etc/ovirt-engine/engine-config/log4j.xml | grep log4j.xml /etc/ovirt-engine/engine-config/log4j.xml: 0 /etc/ovirt-engine/engine-manage-domains/log4j.xml: 0 /etc/ovirt-engine/notifier/log4j.xml: 1

Thanks for the link, for documentation purposes, I'll post my findings here to, so if someone needs this in the future, feel free to use it:

Here is a custom implemented syslog handler for jboss 7.1:

http://randomtekkstuff.blogspot.de/2013/03/jboss-as-7-syslog-handler.html

I will test this out, once I found the jboss module directory..

I think the runtime directory is in /usr/share/ovirt-engine/modules, after ps aux |grep ovirt

In the meantime:

Would ovirt-devs consider it save to "sideload" my own jboss module?

I know this will get painful to maintain once I want to upgrade so I'm already asking:

Is there a chance as a first step to include a custom syslog handler jboss module into ovirt (for jboss < 7.2) ?

I think oVirt uses jboss-modules-maven-plugin to create a module, If you want to create one, the syslog handler in your case, you may create a subproject containing the java code and tweak some of the pom.xml adding the jboss-modules-maven-plugin config, as the other modules do.

Later this could get expanded to easily allow to use syslog..

yeah, I'll try :) 2014-03-20 20:16 GMT+08:00 Sven Kieske <S.Kieske@mittwald.de>:

First: Thanks for the fast answer!

Second: I decided that this is a much too painful hack into ovirt regarding maintainability, thus I will let ovirt log into files like it does already and pipe those into syslog.

But it would be cool if you could work towards integrating this feature into ovirt in the future, maybe for 3.5 or 4.0.

So I created an RFE at:

https://bugzilla.redhat.com/show_bug.cgi?id=1078738

I think many large data centers could use this feature as most people tend to have centralized logging already.
