Hello! Thank you for your reply. Unfortunately, it does not include the hostname with header=true. The following is received by the logserver: { "_index": "ovirt-2016.05.11", "_type": "syslog", "_id": "AVSedM6EH9SU2r3j0ihk", "_score": null, "_source": { "message": "<14>[org.ovirt.engine.core.vdsbroker.HostDevListByCapsVDSCommand] START, HostDevListByCapsVDSCommand(HostName = onodeXXX.some.domain, VdsIdAndVdsVDSCommandParametersBase:{runAsync='true', hostId='XXXXXXXX-XXX-XXXX-XXXX-XXXXXXXXXXX', vds='Host[onodeXXX.some.domain,XXXXXXXX-XXX-XXXX-XXXX-XXXXXXXXXXX]'}), log id: 689d5b30\n", "@version": "1", "@timestamp": "2016-05-11T08:15:35.729+02:00", "type": "syslog", "host": "10.XXX.XXX.XXX", "tags": [ "_grokparsefailure" ], "syslog_severity_code": 5, "syslog_facility_code": 1, "syslog_facility": "user-level", "syslog_severity": "notice" }, "sort": [ 1462947335729, 1462947335729 ] } is it possible to have the IP in the "host" filed have resolved from log4j so that the hostname will be displayed there? Or have it convinced to use the appender.Application field? thank you and best, Dominique ________________________________ Von: Ravi Nori <rnori@redhat.com> Gesendet: Dienstag, 10.

We are using the log4j extension to send ovirt logs to a logstash server. As we do have several engine hosts and only one logging backend, we do need to filter logs by hostname. So far I am unable to provide a hostname in Log4jLogger.properties. All Log4j configurations we have in other applications/servers to honor the log4j.Application property. I tried setting it up by: ovirt.engine.extension.name<http://ovirt.engine.extension.name> = Log4j 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 = logstash-server.something log4j.appender.myappender.Port = 5544 log4j.appender.myappender.ReconnectionDelay = 60000 log4j.appender.myappender.Application = ovirthostname log4j.appender.myappender.LocationInfo = true log4j.appender.myappender.Threshold = DEBUG log4j.appender.myappender.layout = org.apache.log4j.PatternLayout log4j.appender.myappender.layout.ConversionPattern=[%c] %m%n Logs do arrive, but no hostname. Can anyone point me out on how to include the hostname in the logs? thank you and best, Dominique _______________________________________________ Users mailing list Users@ovirt.org<mailto:Users@ovirt.org> http://lists.ovirt.org/mailman/listinfo/users
