8.8.15 Patch32 message log filling on Centos

Postby gmills » Fri Jun 17, 2022 11:35 pm

Hi

Latest 8.8.15 OSE Patch 32 (patched again to fix LDAP issue) is filling the /var/log/messages on Centos 7
The message log is filled with entries like this:
Jun 18 11:11:35 store.xxxxxx.co.nz mailboxd: INFO [mailboxd.csv] [] slogger - ....
Jun 18 11:28:35 store.xxxxxx.co.nz mailboxd: INFO [soap.csv] [] slogger - soap.csv: ...
Jun 18 11:28:35 store.xxxxxx.co.nz mailboxd: INFO [ldap.csv] [] slogger - ldap.csv: ...

These entries were not present before P32
Bug number: ZBUG-2835 though relevant does not seem to work with Centos. I cannot work out how to apply the second change "2. Update line no 210 and remove SLOGGER from statement. "

/opt/zimbra/conf/log4j.properties.in line 210: %%comment VAR:!zimbraLogHostname%%logger.slogger.level=INFO

Thanks
Geoffrey Mills

Apologies for the multiple posting, I was getting an SQL error on posting but turns out the messages were being posted.
Maybe an administrator can purge the duplicates?

Try to restart the Zimbra services after updating to the latest patch.

su - zimbra
zmcontrol restart

Thanks

Solved, workaround the excess logging in /var/log/messages on Centos 7
Reference: https://wiki.zimbra.com/wiki/Log4j2
Reference: https://wiki.zimbra.com/wiki/Current_Known_Issues

Bug number: ZBUG-2835
1. Open /opt/zimbra/conf/log4j.properties.in and update line no 195 and change value to info from debug.
2. Update line no 210 and remove SLOGGER from statement.

I managed to "decode" this line: '2. Update line no 210 and remove SLOGGER from statement'

In the file "/opt/zimbra/conf/log4j.properties.in" locate the block shown below and comment this block out using # prefix:

%%comment VAR:!zimbraLogHostname%%logger.slogger.name = zimbra.slogger
%%comment VAR:!zimbraLogHostname%%logger.slogger.level=INFO
%%uncomment VAR:!zimbraLogHostname%%logger.slogger.level=ERROR
%%comment VAR:!zimbraLogHostname%%logger.slogger.additivity = false
%%comment VAR:!zimbraLogHostname%%logger.slogger.appenderRef.SLOGGER.ref = sloggerAppender

MUST restart mailbox - zmmailboxdctl restart

"/opt/zimbra/conf/log4j.properties.in" has appenders defined for both syslog (LOCAL0) and slogger (LOCAL1) for mailboxd traffic

If there is a better way please do let me know

Hello

I have a log4j issue after applying 8.8.15 Patch 32.

No logs are written to zimbra.log file but only in messages.
The log4j configuration fle is correctly set.

IIt seems that the logs are sent to Rsyslog with a wrong format.

The logs are correctly redirected to zimbra.log if comment the following lines in log4j.properties
appender.SYSLOG.layout.type = PatternLaout
appender.SYSLOG.layout.pattern = imailboxd: %-5p [%t] [%z] %c{1} - %m

My system is CentOS 7 with Rsyslog 8.24.0.57


Thanks
Jerome

Hi,

Sounds more like an OS issue, except you only updated zimbra.
Check rsyslog? /etc/rsyslog.conf and /etc/rsyslogconf.d/, try to follow the logging process

My /etc/rsyslog.conf has these entries at the end of the file:
local0.* -/var/log/zimbra.log
local1.* -/var/log/zimbra-stats.log
auth.* -/var/log/zimbra.log
mail.* -/var/log/zimbra.log

has /var/log/zimbra-stat.log got data coming in (local1.*)

And in /opt/zimbra/conf/log4j.provider:
# Syslog appender
appender.SYSLOG.type = Syslog
appender.SYSLOG.name = syslogAppender
appender.SYSLOG.host = localhost <-- in /etc/hosts?
appender.SYSLOG.port = 514 <-- not blocked?
appender.SYSLOG.protocol = UDP
appender.SYSLOG.facility = LOCAL0
appender.SYSLOG.layout.type = PatternLayout
appender.SYSLOG.layout.pattern = mailboxd: %-5p [%t] [%z] %c{1} - %m

# Logger service appender
appender.SLOGGER.type = Syslog
appender.SLOGGER.name = sloggerAppender
appender.SLOGGER.host = store.xxxxx.co.nz
appender.SLOGGER.facility = LOCAL1
appender.SLOGGER.port = 514
appender.SLOGGER.protocol = UDP
appender.SLOGGER.layout.type = PatternLayout
appender.SLOGGER.layout.pattern = mailboxd: %-5p [%t] [%z] %c{1} - %m

Are the log files in /opt/zimbra/log/ working?
Restart rsyslog service and look for errors in /var/log/messages?
I also ran zmfixperms at some stage https://wiki.zimbra.com/wiki/Fix_the_Zimbra_Collaboration_Permissions
Suspect you have looked at most of these though...
I vaguely remember some Zimbra Wiki pages on getting logging working properly in multi-server environment, had to use these when I set Zimbra up

Geoffrey

Hello Geoffroy

Thans for you advice

But in fact, it's a PatternLayout issue
The faliciy is not trasmitted by default

The pattern must be changed to
appender.SYSLOG.layout.pattern = <134> %d{MMM dd HH:mm:ss} ${hostName} mailboxd: %-5p [%t] [%z] %c{1} - %m



But some issue persist
In release 8.8.15 P31 the zimbra.log contains all mailboxd messages
And qith the new Patch these messages are only store in the /opt/zimbra/log/mailboxd.log file


Perhaps something missing at the rootlogger level

I only have these 2 lines
rootLogger.level=INFO
rootLogger.appenderRef.LOGFILE.ref = mailboxFile

Thanks
Jerome

Hi Jerome,

OK, my 2cents worth and I could be totally wrong so ignore me if required.

The pattern must be changed to
appender.SYSLOG.layout.pattern = <134> %d{MMM dd HH:mm:ss} ${hostName} mailboxd: %-5p [%t] [%z] %c{1} - %m


OK, this redirects (appends) data from existing logs into SYSLOG but this is the *wrong* data.

No logs are written to zimbra.log file but only in messages.


I think postfix, amavis, etc log *direct* to SYSLOG (via local0), not sure if they use the java log4j logging. These do not log in /opt/zimbra/log/mailbox.log anyway.

https://wiki.zimbra.com/wiki/Log_Files
The MTA (postfix) logs via syslog to the mail facility. By default, this goes to /var/log/maillog, but Zimbra sets it to /var/log/zimbra.log

On my Zimbra store server, use zimbra "postconf" utility to display logging destination for postfix:
[zimbra@store conf]$ /opt/zimbra/common/sbin/postconf maillog_file
maillog_file =

The "maillog_file=" is empty therefore postfix is logging to syslog

Is our Centos logging working? https://www.poftut.com/linux-logger-command-usage-tutorial-with-examples/
Looking at the end of /etc/rsyslog.conf, "local0" logs to /var/log/zimbra.log

Test it:
logger -p "local0.info" Test log to local0.info
This message is displayed in /var/log/zimbra.log, so logging to local0 is working

Reset logging for multi-server setup:
https://wiki.zimbra.com/wiki/Configuring-Logger-Host
is Zimbra zmlogger running?

PS: Are you using Centos syslog or rsyslog - I remember I changed my one over to rsyslog
PPS: selinux running - caused me many issues originally - /opt/zimbra/libexec/zmfixperms -e -v

/opt/zimbra/log/mailbox.log: <-- mailboxd logs, traffic volumes, etc but not mail send/receive data
