Cluster Management and Administration 153
More details on how to configure HAView and on how to monitor your cluster
with HAView can be found in Chapter 3, “Monitoring an HACMP cluster” in
HACMP for AIX, Version 4.3: Administration Guide
, SC23-4279.
8.1.3 Cluster Log Files
HACMP for AIX writes the messages it generates to the system console and
to several log files. Because each log file contains a different subset of the
types of messages generated by HACMP for AIX, you can get different views
of cluster status by viewing different log files. HACMP for AIX writes
messages into the log files described below. See Chapter 2, “Examining
Cluster Log Files”, in the
HACMP for AIX, Version 4.3: Troubleshooting
Guide,
SC23-4280
for more information about these files.
8.1.3.1 /var/adm/cluster.log
The
/var/adm/cluster.log file is the main HACMP for AIX log file. HACMP
error messages and messages about HACMP for AIX-related events are
appended to this log with the time and date when they occurred.
8.1.3.2 /tmp/hacmp.out
The /tmp/hacmp.out
file records the output generated by the configuration
and startup scripts as they execute. This information supplements and
expands upon the information in the /var/adm/cluster.log file. To receive
verbose output, the Debug Level run-time parameter should be set to
high
,
which is the default.
8.1.3.3 /usr/sbin/cluster/history/cluster.
mmdd
The /usr/sbin/cluster/history/cluster.mmdd file contains timestamped,
formatted messages generated by HACMP for AIX scripts. The system
creates a cluster history file whenever cluster events occur, identifying each
file by the file name extension
mmdd
, where
mm
indicates the month and
dd
indicates the day.
While it is more likely that you will use these files during troubleshooting, you
should occasionally look at them to get a more detailed picture of the activity
within a cluster.
8.1.3.4 System Error Log
The system error log file contains timestamped, formatted messages from all
AIX subsystems, including HACMP for AIX scripts and daemons. Cluster
events are logged as operator messages (error id: AA8AB241) in the system
error log.
