default suppresses duplicate messages. If you issue multiple logger test messages, make
sure each is unique.
3.3.2.2 Manually Configuring a Serviceguard Cluster as a Log Consolidation Server
Configuring a Serviceguard cluster as a log consolidation server is similar to the steps for a single
system. All cluster members must be up and accessible before proceeding.
Create the configuration files described below on every cluster member. The simplest approach
is to configure one member completely and then copy each configuration file clusterwide. The
cexec and ccp tools can simplify replicating changes clusterwide.
For a cluster configuration, syslog-ng is configured as a package so the log consolidation
service is highly available. The package must be named clog and the package configuration
files require the following information:
• Registered IP address and DNS name for the clog package
• The subnet associated with that IP address
• Clusterwide storage configuration using LVM or VxVM
• A filesystem configured on the clusterwide storage, that can be ext3 or CFS. Since consolidated
logs grow rapidly, HP recommends that the filesystem be configured using the largefiles
option and that there is room for growth.
Complete IP address registration and storage/filesystem configuration before continuing. For
additional information on creating the Serviceguard storage/filesystem configuration for a
package, refer to the Managing Serviceguard manual.
Refer to the section “Cluster Configuration Notes for clog” (page 55) for an overview of how to
configure consolidated logging in a cluster.
