ovirt-engine-extension-logger-log4j provides the ability to pass oVirt Engine logs to remove syslog instance: https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.4/html/administration_guide/enabling_the_ovirt_engine_extension_logger_log4j Unfortunately ovirt-engine-extension-logger-log4j depends on log4j 1.y, which containns several CVEs. We are going to use JBoss Log Manager within ovirt-engine itself to provide similar functionality: https://docs.wildfly.org/23/wildscribe/subsystem/logging/syslog-handler/index.html https://magnus-k-karlsson.blogspot.com/2019/03/syslog-handler-in-jboss-eap-6-and-7.html This means that ovirt-engine-extension-logger-log4j will be obsoleted by ovirt-engine package itself
Verified on: ovirt-engine-4.4.10.6-0.1.el8ev.noarch ovirt-engine-extension-logger-log4j not present on new installations of RHV and on upgrade from previous versions where it was present. Also, log4j12 can be remove from the machine without interfering with the engine
Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory (Low: RHV Manager (ovirt-engine) security update [ovirt-4.4.10-1]), and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://access.redhat.com/errata/RHSA-2022:0475
Do we need a doc bug explaining how to reconfigure the syslog configurations to work after the successor of ovirt-engine-extension-logger-log4j will take its part in reporting engine logs to syslog remote server or we're terminating this functionality and syslog server won't be supported anymore? How customers should handle upgrade flow with deployed engine<= 4.4.9 with this extension and configured to forward the logs to some syslog server, then upgrade the engine to >= 4.4.10, log forwarding might be broken.
Obsoleting ovirtt-engine-extension-logger-log4j should be mentioned in 4.4.10 release notes and also relevant administration guide has been updated: https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.4/html/administration_guide/chap-log_files#Enabling_SyslogHandler_RHV_Manager_logs
