Reviewing the System Log File
Messages from the Cluster Manager and Package Manager are written
to the system log file. The default location of the log file is
/var/adm/syslog/syslog.log. Also, package-related messages are
logged into the package log file. The package log file is located in the
package directory, by default. You can use a text editor, such as vi, or
the more command to view the log file for historical information on your
cluster.
It is always a good idea to review the syslog.log file on each of the
nodes in the cluster when troubleshooting cluster problems.
This log provides information on the following:
• Commands executed and their outcome.
• Major cluster events which may, or may not, be errors.
• Cluster status information.
NOTE Many other products running on HP-UX in addition to Serviceguard use
the syslog.log file to save messages. The HP-UX Managing Systems and
Workgroups manual provides additional information on using the system
log.
Sample System Log Entries
The following entries from the file
/var/adm/syslog/syslog.log show
a package that failed to run due to a problem in the pkg5_run script. You
would look at the pkg5_run.log for details.
