HP UX System Adstration manual If using the TCP protocol, add the following lines

3.The syslog-ngstartup procedure, /sbin/init.d/syslog-ng, relies on several configuration variables. Edit /etc/rc.config.d/syslog-ngas follows:

a.Change the CLOG_CONFIGURED line to:

CLOG_CONFIGURED=1

b.Add the following lines:

CLOG_CONSOLIDATOR=0

CLOG_CONS_IP=IP address of the log consolidator

c.If using the TCP protocol, add the following lines:

CLOG_TCP=1

CLOG_TCP_PORT=log consolidation server tcp port

If using ssh port forwarding, add:

CLOG_SSH=1

CLOG_SSH_PORT=ssh port chosen otherwise, add:

CLOG_SSH=0

otherwise, if using the UDP protocol, add:

CLOG_TCP=0

If consolidating the local syslogs, add:

CLOG_SYSLOG=1 otherwise add:

CLOG_SYSLOG=0

If consolidating this cluster’s package logs, add:

CLOG_PACKAGE=1 otherwise, add:

CLOG_PACKAGE=0

4.All the files edited thus far need to be distributed cluster-wide:

# ccp /etc/syslog-ng.conf.client /etc/

# ccp /etc/rc.config.d/syslog-ng /etc/rc.config.d/

Create the following symbolic link on each cluster member:

# ln -sf /etc/syslog-ng.conf.client /etc/syslog-ng.conf

5.When using TCP with ssh port forwarding, record the ssh port number you chose above in the /etc/services file. For example, add the line:

clog_ssh 1776/tcp

# Consolidated logging with ssh port forwarding

Add this line to the /etc/services file of each cluster member.

6.To consolidate this cluster’s package logs, additional manual steps are needed on the log consolidation server. Each time a package is created or deleted on this cluster, these steps need to be done. Refer to “Consolidating Package Logs on the Log Consolidation Server” (page 74).
