HP Insight Control for Linux 6.0 User Guide

21.7.2 The syslog-ng.conf rules file
The syslog-ng.conf rules file defines the order of importance by which the log files are
arranged.
The /opt/hptc/syslog-ng/etc/syslog-ng/syslog-ng.conf file defines a series of rules
for the syslogng_forward service on how to handle messages from its clients. The
syslog-ng.conf file contains five types of rules:
Options Defines generic information such as reconnection timeouts, FIFO size limits,
and so on.
Sources Defines the different sources from which messages are obtained.
Filters Defines the rules to segregate messages. For example, messages can be
separated by host, severity, facility, and so on.
Destinations Contains the devices and files where the messages are sent or saved.
Logs Combines the sources, filters, and destination into specific rules to handle
the different messages.
You can use a text editor such as emacs or vi to read the log files, and you can use a variety of
text manipulation commands to find, sort, and format these log files.
21.7.3 Modifying the syslog-ng rules files
HP Insight Control for Linux supplies a default configuration for the syslog-ng rules. You can
modify the syslog-ng rules configuration by modifying template files.
The syslog-ng rules are contained in the following template:
Global Template
Dictates the syslog-ng rules. The full path name is /opt/hptc/
syslog-ng/etc/global/syslog_ng_global_template
For more information on the parameters that make up these templates, see the syslog-ng
documentation at the following website:
http://www.balabit.com/products/syslog_ng/
The syslog-ng nconfigure script uses these template files to build the /opt/hptc/
syslog-ng/etc/syslog-ng/syslog-ng.conf file.
To modify the syslog-ng rules, follow these steps:
1. Log in to the CMS as root.
2. Change to the /opt/hptc/syslog-ng/etc directory:
# cd /opt/hptc/syslog-ng/etc
3. Make a backup copy of the template file:
# cp global/syslog_ng_global_template global/template_backup
4. Use a text editor to modify the template file.
5. Restart the syslog-ng service:
# /etc/init.d/syslog-ng restart
21.8 Changing the number of concurrent tasks
The number of concurrent tasks that HP Insight Control for Linux can run depends on the
following:
• The type of task being run.
Each task is assigned a certain weight value. The /opt/mx/icle/icelx.execution.xml
file lists the weight values for each type of task.
