24.6. Enabling the oVirt Engine Extension Logger log4j

Install the extension.

# yum install ovirt-engine-extension-logger-log4j

Create the Log4jLogger.properties file in the /etc/ovirt-engine/extensions.d/ directory and include the following contents.

ovirt.engine.extension.name = log4jlogger
ovirt.engine.extension.provides = org.ovirt.engine.api.extensions.logger.Logger
ovirt.engine.extension.bindings.method = jbossmodule
ovirt.engine.extension.binding.jbossmodule.module = org.ovirt.engine-extensions.logger.log4j
ovirt.engine.extension.binding.jbossmodule.class = org.ovirt.engineextensions.logger.log4j.Log4jLogger
log4j.rootLogger=DEBUG, myappender
log4j.appender.myappender=org.apache.log4j.net.SyslogAppender
log4j.appender.myappender.SyslogHost=localhost
log4j.appender.myappender.layout=org.apache.log4j.PatternLayout
log4j.appender.myappender.layout.ConversionPattern=[%c] %m%n

Install and configure rsyslog.

# yum install rsyslog

Configure SELinux to allow rsyslog traffic.

# semanage port -a -t syslogd_port_t -p udp 514

Edit /etc/rsyslog.conf and add the following lines:

$template TmplAuth, "/var/log/%fromhost%/secure"
$template TmplMsg, "/var/log/%fromhost%/messages"

$RuleSet remote
authpriv.*   ?TmplAuth
*.info,mail.none;authpriv.none,cron.none   ?TmplMsg
$RuleSet RSYSLOG_DefaultRuleset
$InputUDPServerBindRuleset remote

Uncomment the following two lines.

#$ModLoad imudp
#$UDPServerRun 514

Restart the rsyslog service:

# systemctl restart rsyslog.service

If the firewall is enabled and active, run the following command to add the necessary rules for opening the rsyslog ports in Firewalld.

# firewall-cmd --permanent --add-port=514/udp
# firewall-cmd --reload

Restart Red Hat Virtualization Manager.

# restart ovirt-engine
