Log File

Brief list of the major log files in Zimbra and what they contain

  • /opt/zimbra/log/mailbox.log - Zimbra Mailboxd (jetty) writes all mailbox activity to this log file. This activity can be anything from moving a message to deletion of an account.
  • /opt/zimbra/log/zmmailboxd.out – Mailboxd(jetty) logs to this file during startup.
  • /opt/zimbra/log/audit.log – Logs authentication activity.

  • /opt/zimbra/log/myslow.log – Consists sql statements which took more than long_query_time seconds (zimbra default – 1second) to execute and required atleast min_examined_row_limit (zimbra default - 0) rows to be examined.
  • /opt/zimbra/log/nginx.access.log - NGINX writes information about client requests after the request is processed.
  • /opt/zimbra/log/nginx.log – Nginx error log which defaults to “info” in Zimbra.
  • /opt/zimbra/log/spamtrain.log – Spam training log.
  • /opt/zimbra/log/ews.log – EWS server side activity.
  • /var/log/zimbra.log – All MTA (Postfix, amavisd, antispam, antivirus,cyrus-sasl)/Ldap logs go to this file.
  • /var/log/zimbra-stats.log – Logger data gets logged to this file.

Log Rotation

Two different log rotation daemons handle log rotation of the zimbra log files.

  • Log4j
    • Log4j is responsible for logging to mailbox.log, audit.log, sync.log, synctrace.log,webxml.log and ews.log. For config : /opt/zimbra/conf/log4j.properties

Example, below the are the config options for the rotation of /opt/zimbra/log/mailbox.log

log4j.appender.LOGFILE=org.apache.log4j.rolling.RollingFileAppender
log4j.appender.LOGFILE.RollingPolicy=org.apache.log4j.rolling.TimeBasedRollingPolicy
log4j.appender.LOGFILE.RollingPolicy.FileNamePattern=/opt/zimbra/log/mailbox.log.%d{yyyy-MM-dd}
log4j.appender.LOGFILE.File=/opt/zimbra/log/mailbox.log
log4j.appender.LOGFILE.layout=com.zimbra.common.util.ZimbraPatternLayout
log4j.appender.LOGFILE.layout.ConversionPattern=%d %-5p [%t] [%z] %c{1} - %m%n
