[SOLVED] CentOS-7.4 - rsyslog - imjournal: journal reloaded...

[anderson_thomas]

Hi,

.... imjournal: journal reloaded... [v8.24.0 try http://www.rsyslog.com/e/0 ]

after upgrade from CentOS 7.3 to 7.4 these message are coming
periodically every day from rsyslog.

What does this mean and how can I fix this?

p.s. I think, the rsyslog forum are not much visited, so there was no answer till now...

Thank you!
Klaus.

Could it be logrotate, rotating the logs and restarting rsyslog so it gets rid of (what are now stable handles - if the logs where rotated)?

[anderson_thomas]

Hi aks,

no, I don't think so, beacuse the messages are written more than once a day be one server. See the following line from my /var/log/messages:

Code: Select all

Sep 24 05:56:46 server10 rsyslogd: imjournal: journal reloaded... [v8.24.0 try http://www.rsyslog.com/e/0 ]

Sep 24 23:22:09 server10 rsyslogd: imjournal: journal reloaded... [v8.24.0 try http://www.rsyslog.com/e/0 ]

The only differnt to a lokal workstation with CentOS-7.4 is, that I submit all log entrys from the server10 to a "Graylog" server via Remote-Logging, see my extra configuration from /etc/rsyslog.conf (whole configuration file):

Andy ideas?


Thank you!

Well I don't use imjournal because of the well known performance hot - see http://www.rsyslog.com/doc/v8-stable/co ... urnal.html

Following the link suggested (int he output) points to: http://kb.monitorware.com/kbeventdb-detail-id-7218.html (they suggest disabling xconsole stuff).

Also have a look at https://www.freedesktop.org/software/sy ... .conf.html for journal options (I just wonder if the journal is "full" - I seem to recall that is configurable option and perhaps journald is resetting in some manner - thus "forcing" rsyslog to reload/restart), but that's a guess.

Hi aks,

o.k. NOT to use imjournal is maybe the best possibility.

I try to disable imjournal, BUT after that, NO logging was done in any log file?

Can you give me an example of an /etc/rsyslog.conf AND other dependencies, how I can I use rsyslog without using imjournal?

Thank you!
Klaus.

[anderson_thomas]

Hi aks,

SORRY - I found my mistake - LOGGING is now working without imjournal.

/etc/rsyslog.conf

Code: Select all

# default: $OmitLocalLogging on
$OmitLocalLogging off

Was my fault!

Thank you!
Klaus.

Hi,

thank you aks for the tip!

I think NOT to use the imjournal module will solve the problem!

Here my complete /etc/rsyslog.conf for example:
