smit perrdemon_shw
You can alter one or more of the configuration parameters for the AIX Error Log
on a set of nodes. Because the additional entries are generated by SP System
software, the AIX Error Log file size should be a minimum of 4 MB.
The fast path invocation for the Change Characteristics of the Error Log menu is:
smit perrdemon_chg
Managing Error Templates
You can create a new error template in the Error Template repository for logging
errors. The fast path invocation for the Add an Error Template menu is:
smit padd_et
You can remove a template from the Error Template Repository using the fast
path invocation for the Error Template menu:
smit prem_et
You can display entries from the Error Template Repository to the local host by
using the fast path invocation for the Show an Error Template menu:
smit pshw_rt
6.2.3 BSD syslog Facility
SP error logging utilizes the BSD syslog facility for recording error events.
Some applications use syslog for logging errors and other events.
Administrators also find it desirable to be able to list error log messages and
syslog messages in one single report.
To access the syslog menu in SMIT, enter:
smit spsyslog
Generating Reports on BSD syslog Log Files
The syslogd daemon, which logs the errors, is configured with a file designating
filters for the incoming messages to determine their destination. The default
configuration file is /etc/syslog.conf. BSD syslog errors are classified by the
facility that is issuing the error and by the error
′
s priority value. Refer to syslogd
daemon later in this topic for a description and overview of facility and priority
values. Entries in the configuration file determine the destination for each error
message based on these values. Destinations can be a file, user ID or the
syslogd daemon on another machine. We recommend that error messages be
kept locally rather than forwarding to a remote syslogd daemon on another
machine, because of the increased network traffic. You can use file collections
to maintain consistent configuration of the syslog facility.
A syslog file has the following format:
MMM DD HH:MM:SS node_name resource{pid}: mesg
Where:
MMM DD HH:MM:SS Is the timestamp: Month Day Hour:Minute:Second
node_name The name of the node that the error occurred on
resource The name of the failing system
