Properly Configured Rsyslog on CentOS
- by Gaia
I'm trying to configure Rsyslog 5.8.10 on CentOS 6.4 to send Apache's error and access logs to a remote server. It's working, but I have a couple questions.
A) I would like to use as few queues (and resources) as possible. I send error logs to server A, send access logs to server A, send both logs in one stream to server B. Should I specify one queue per external service (2 queues) or one queue per stream (3 queues, as I have now)? This is what I have:
$ActionResumeInterval 10
$ActionQueueSize 100000
$ActionQueueDiscardMark 97500
$ActionQueueHighWaterMark 80000
$ActionQueueType LinkedList
$ActionQueueFileName logglyaccessqueue
$ActionQueueCheckpointInterval 100
$ActionQueueMaxDiskSpace 1g
$ActionResumeRetryCount -1
$ActionQueueSaveOnShutdown on
$ActionQueueTimeoutEnqueue 10
$ActionQueueDiscardSeverity 0
if $syslogtag startswith 'www-access' then @@logs-01.loggly.com:514;logglyaccess

B) Does a queue block get used over and over by every send action that follows it or only by the first one or only until it encounters a send followed by a discard action (~)?
C) How do I reset a queue block so that an upcoming send action does not use a queue at all?
D) Does a TLS block get used over and over by every send action that follows it or only by the first one or only until it encounters a send followed by a discard action (~)?
E) How do I reset a TLS block so that an upcoming send action does not use TLS at all?
F) If I run rsyslog -N1 I get:
rsyslogd -N1
rsyslogd: version 5.8.10, config validation run (level 1), master config /etc/rsyslog.conf
rsyslogd: WARNING: rsyslogd is running in compatibility mode. Automatically generated config directives may interfer with your rsyslog.conf settings. We suggest upgrading your config and adding -c5 as the first rsyslogd option.
rsyslogd: Warning: backward compatibility layer added to following directive to rsyslog.conf: ModLoad immark

Where do I place the -c5 so that it doesnt run in compatibility mode anymore?
