#
When you want to configure the system so that HDLM messages are output to
syslog, specify
user
for the facility in the
/etc/syslog.conf
file. The
following shows an example where the system function name is
user
, and
messages at the
info
level or higher are output to the
/tmp/syslog.user.log
file:
user.info /tmp/syslog.user.log
For details on error levels, see 2.10.2 Filtering of error information.
2.10.2 Filtering of error information
Errors detected by HDLM are classified into various error levels. Table 2-8: Error
levels lists the error levels, in the order of most to least severe.
Table 2-8: Error levels
Error information is filtered according to the error level, and then collected.
In syslog, the HDLM messages on or above the level set by the user configured in
/
etc/syslog.conf
are collected. It is recommended that you set the Information to
be output at the info level or higher.
The error information in error logs and trace files are collected based on a user-defined
collection level. The collection levels are as follows:
