I have a postfix mailserver that works fine except for the logrotate.
syslog.conf
mail.* -/var/log/mail.log
logrotate.conf
/var/log/mail.log {
[Code]....
So when cron does the logrotate, there is a new logfile but its empty. After i restart the syslogd it gets back to its normal logging.
What am i missing? All this works with CentOS, why is Ubuntu such a pain...
Is the logrotate.conf settings global/apply to what is in logrotate.d/? I have olddir /var/log/old_logs in logrotate.conf but logrotate is not placing old rsyslogs in /var/log/old_logs for logrotate.d/rsyslog

server.nov-20.2010.log
server.nov-21.2010.log
server.nov-22.2010.log
server.nov-23.2010.log
i'd like to have logrotate compress the logs that are older than 3 days. Is this possible with logrotate, or do i just schedule a cron job to bzip everything under the folder older than 3 days?
We started hosting some very large content on our site, and the usage patterns in cacti have revealed that the HTTP sessions through our load-balancers drop off dramatically right at midnight.
The logrotate process runs right at midnight, and issues a reload command through the service tool (CentOS 5.5):
Code:
$ cat /etc/logrotate.d/httpd
/data/websites/logs/*_log /var/log/httpd/*log {
missingok
daily
dateext
compress
rotate 7
sharedscripts
postrotate
/sbin/service httpd reload > /dev/null 2>/dev/null || true
endscript
}
Looking at the init script reveals that the reload section is suppose to trigger a HUP of the httpd process:
Code:
reload() {
echo -n $"Reloading $prog: "
if ! LANG=$HTTPD_LANG $httpd $OPTIONS -t >&/dev/null; then
RETVAL=$?
echo $"not reloading due to configuration syntax error"
failure $"not reloading $httpd due to configuration syntax error"
else
killproc -p ${pidfile} $httpd -HUP
RETVAL=$?
fi
echo
}
In which, Apache should reload it's configuration and start the new logfile without breaking current sessions. However that clearly isn't what is going on. I'm tempted to edit the logrotate script to trigger a HUP directly by cat'ing the PID file directly. Is this normal behavior for Apache when signaled with a HUP?
I have an Ubuntu server, and I have a special script on logrotate.d to rotate the samba_audit logs:

I would expect this behavior if "domain.com and anotherdomain.com" wasn't a domain that I hosted. But this is a valid domain that this server should be answering for. In my named.conf I do have the

I am wondering if there is a way to to divide the hour by 12, making a new log file every 5 minutes. We have been using LogRotate, but when Syslog-NG is restarted we have some data loss. Is this possible? Another solution I can think of would be to add $R_MINUTE (or whatever it is) and run a cron job every 5 minutes to concatenate the files.

View 1 Replies View RelatedRHEL 5.4 i want to be able to do redistribution of inbound syslog messages to syslogd. as example, my syslog.conf has in it at the end:
*.* @192.168.5.5
*.* @192.168.5.6
my sysconfig/syslog file has "-r" as the only option for syslogd. any messages generated by the localhost will be sent to the two remote servers, but messages that come into this box (udp 514) only get logged locally and do not get sent out to the remote hosts.
you may ask why do i want to do this. because i have several syslog servers (for security purposes) and many of my net devices are configured to send syslog to all the syslog servers, hence each device is sending way too much duplicate udp-514. so i would like to minimize the udp-514 coming out of the devices, have all devices send to a central syslog server, and then central syslog server do distribution to the other syslog servers. others have also called this "syslog proxy". or, if not with syslogd, how to achieve this (preserving the original syslog message host info, etc)?
I am writing my own syslog collector, but im stuck with calculating the severity of the message. The PRI value is calculated:-
Code:
(Facility * 8) + Severity
But from the context of a collector, neither Facility or severity would be known? You need to know either severity or Facility to calculate facility or severity?! The RFC goes in to no more detail about calculating the severity value, other tan this expression.
