I have several network appliances, and I want aggregate their syslog output for later analysis. Eventually I might think about a Splunk box, but for the interim I'm hoping to just build a CentOS 6 syslog server and have it aggregate everything on it for quick review.
I installed rsyslog and am looking through the /etc/rsyslog.conf file for what I configure to (a) listen for syslog input from other devices (UDP port 514 is fine), (b) make a log, and (c) log rotate files.
(a) I see in there (if I comment it out)
# Provides UDP syslog reception $ModLoad imudp $UDPServerRun 514
(Obviously add an iptables rule to let this traffic in)
(b) I see options in there, but am not sure how to separate the local logs from the remote logs. Is it something like the following?
*.*;local6.none; auth,authpriv.none -/var/log/syslog
(c) I understand I can do if I edit /etc/logrotate.d/MyNetworkAppliance.log. This isn't as big of a concern right now. Just trying to figure out how to log things separately. :/
Any suggestions on what I should do to make this work?
Hello,
this is how I do it.
(c)
$template Tdefault,"/logs/%fromhost-ip%/%syslogfacility-text%.%$YEAR%-%$MONTH%-%$DAY%.log" $template FileFormat,"%TIMESTAMP:::date-rfc3339% %HOSTNAME% %syslogtag%%msg:::sp-if-no-1st-sp%%msg:::drop-last-lf%\n"
*.* -?Tdefault;FileFormat
(b) Dropping not localhost. All event not from localhost are _dropped_ because of the following rule. This is the end of the config file, dealing only with local logs:
:fromhost-ip, !isequal, "127.0.0.1" ~
#kern.* /dev/console
# Log anything (except mail) of level info or higher. # Don't log private authentication messages! *.info;mail.none;authpriv.none;cron.none /var/log/messages
...and so on (standart rsyslog.conf). Mind the line breaks, if lines are wrapped in email.
