Conﬁguring a

Serviceguard

Cluster as a Log

Forwarding Client

Conﬁguring a Serviceguard cluster as a log forwarding client is similar to

conﬁguring a single system. All cluster members must be up and

accessible before proceeding. You will ﬁrst conﬁgure syslogd, then

syslog-ng.

Create the conﬁguration ﬁles described below on every cluster member.

The simplest approach is to completely conﬁgure one member and then

copy each conﬁguration ﬁle cluster-wide. The cexec and ccp tools can

simplify replicating changes cluster-wide.

Step 1. If you want the syslog messages for the cluster to be forwarded to the

log consolidator, do the following:

a. Start by conﬁguring the standard syslogd to co-exist with a

syslog-ng forwarder. By default, syslogd listens for incoming log

messages on UDP port 514. To forward this cluster’s syslogs,

syslog-ng must listen on UDP port 514. Edit

/etc/rc.config.d/syslogd and change SYSLOGD_OPTS to add the

-N switch; this prevents syslogd from listening on port 514. For

example,

SYSLOGD_OPTS=“-D -N”

b. Edit the system’s /etc/syslog.conf ﬁle to forward log messages to port

514 on the local host where they will be read by syslog-ng. Using the

HP-UX default /etc/syslog.conf as the example, add the following

lines:

mail.debug @<fully qualified hostname>

*.info;mail.none @<fully qualified hostname>

where <fully qualified hostname> is the fully qualiﬁed hostname

of this cluster member. This name must be fully qualiﬁed or syslogd

will not forward the messages properly.

If you have customized syslog.conf, make sure to add the

forwarding lines for your customizations as well.

c. syslogd must be stopped and restarted for these changes to take

effect:

# /sbin/init.d/syslogd stop

# /sbin/init.d/syslogd start

d. Since /etc/rc.config.d/syslogd is generic, it can be distributed

cluster-wide using ccp:

# cpp /etc/rc.config.d/syslogd /etc/rc.config.d/
