3: Error, 4: Warning, 6: Informational

If you use Ctrl + C to cancel the DLMgetras utility for collecting HDLM

error information, audit log data indicating that the DLMgetras utility has

terminated will not be output.

Requirements for Outputting Audit Log Data

HDLM can output audit log data when all of the following conditions are

satisfied:

• The syslog daemon is active.

• The output of audit log data has been enabled by using the HDLM

command's set operation.

However, audit log data might still be output regardless of the above

conditions if, for example, an HDLM utility is executed from external media.

The following audit log data is output:

Categories: StartStop, Authentication, and ConfigurationAccess

Severity: 6 (Critical, Error, Warning, or Informational)

Destination: syslog (facility value: user)

Notes:

You might need to perform operations such as changing the log size

and backing up and saving collected log data, because the amount of

audit log data might be quite large.

If the severity specified by the HDLM command's set operation differs

from the severity specified by the configuration file /etc/

syslog.conf, the higher severity level is used for outputting audit log

data.

Destination and Filtering of Audit Log Data

Audit log data is output to syslog. Because HDLM messages other than audit

log data are also output to syslog, we recommend that you specify the

output destination that is used exclusively for audit log data.

For example, to change the output destination of audit log data to /usr/

local/audlog, specify the following two settings:

• Specify the following setting in the /etc/syslog.conf file:

local0.info /usr/local/audlog

• Use the HDLM command's set operation to specify local0 for the audit

log facility:
