System logs are empty (/var/log/messages; /var/log/secure; etc)

  • 772

I found that rsyslog stopped writing on logs (messages; secure; cron;etc)

System information: NAME="Red Hat Enterprise Linux Server" VERSION="7.4 (Maipo)" ID="rhel" ID_LIKE="fedora" VARIANT="Server" VARIANT_ID="server" VERSION_ID="7.4"

already restarted rsyslog with no results. Other logs processed by rsyslogd are being writen without issues.

Also restarted systemd-journald.

Already deleted /run/log/journal/* and restarted journald Already deleted imjournal.state and restarted rsyslog

    well... almost 2 years had gone by and finally found the solution for the issue. If anyone has the same issue please try the steps below.

    syslogd version rsyslogd 8.24.0-38.el7

    The issue was related to the imjournal module. I've remove all the entries of the rsyslog.conf related to imjournal and switched the OmitLocalLogging to off

    After that I've restarted the rsyslog service using systemctl restart rsyslog and the log entries started to be populated to the log file that I've configured in rsyslog.conf.

    The rsyslog.conf file now looks like this:

    $ModLoad imuxsock
#$ModLoad imjournal
$ModLoad immark 
$WorkDirectory /var/lib/rsyslog
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
$IncludeConfig /etc/rsyslog.d/*.conf
$OmitLocalLogging off
#$IMJournalStateFile imjournal.state
*.info;mail.none;authpriv.none;cron.none                /var/log/messages
authpriv.*                                              /var/log/secure
mail.*                                                  -/var/log/maillog
cron.*                                                  /var/log/cron
*.emerg                                                 :omusrmsg:*
uucp,news.crit                                          /var/log/spooler
local7.*                                                /var/log/boot.log
local3.*                                                /var/log/sshd-second.log

  2. A bug fix for a problem where rsyslog would stop writing entries from the systemd journal was released in errata RHBA-2017:2306. Ensure that your system is up to date.

  3. If logs are not written to /var/log/messages. You just need to restart rsyslog

    -> On RHEL 7

    systemctl restart rsyslog

    cat /var/log/messages

    -> ON RHEL6

    service rsyslog restart

    cat /var/log/messages
