6.6 Logging Node Events
The syslog-ng program is a flexible and scalable audit trail processing tool, and it provides a
centralized, securely stored log of all devices on your network. This tool completely replaces
syslogd; running b o th syslog-ng and syslogd on the sam e system causes a deadlock,
hanging the system.
The /opt/hptc/syslog-ng/etc/syslog-ng.conf file defines a series of rules on
how to handle messages logged in the system. The syslog-ng.conf file is divided into five
sections:
Options Defines generic information like re- conn
ection time-outs, FI FO
size limits, and so on.
Sources
Defines the different sources from wh
ich the messages are ob tain ed.
Filters Define the rules to segregate messag
es. F or example, messages can
be separated by host, severity, faci
lity, and so on.
