[ovirt-users] Log4j hostname

[Dominique Taffin]

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

Hi Dominique,

Add

log4j.appender.myappender.header = true

and see if you get the hostname

Hello!


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
