traceoptions (Security Log)

Syntax

Hierarchy Level

Description

Configure security log tracing options.

Options

• file—Configure the trace file options.

  • filename—Name of the file to receive the output of the tracing operation. Enclose the name within quotation marks. All files are placed in the directory /var/log. By default, the name of the file is the name of the process being traced.

  • files number—Maximum number of trace files. When a trace file named trace-file reaches its maximum size, it is renamed to trace-file.0, then trace-file.1, and so on, until the maximum number of trace files is reached. The oldest archived file is overwritten.

    If you specify a maximum number of files, you also must specify a maximum file size with the size option and a filename.

    Range: 2 through 1000 files

    Default: 10 files

  • match regular-expression—Refine the output to include lines that contain the regular expression.

  • size maximum-file-size—Maximum size of each trace file, in kilobytes (KB), megabytes (MB), or gigabytes (GB). When a trace file named trace-file reaches this size, it is renamed trace-file.0. When the trace-file again reaches its maximum size, trace-file.0 is renamed trace-file.1 and trace-file is renamed trace-file.0. This renaming scheme continues until the maximum number of trace files is reached. Then the oldest trace file is overwritten.

    If you specify a maximum file size, you also must specify a maximum number of trace files with the files option and a filename.

    Syntax: x K to specify KB, x m to specify MB, or x g to specify GB

    Range: 10 KB through 1 GB

    Default: 128 KB

  • world-readable | no-world-readable—By default, log files can be accessed only by the user who configures the tracing operation. The world-readable option enables any user to read the file. To explicitly set the default behavior, use the no-world-readable option.

• flag—Trace operation to perform. To specify more than one trace operation, include multiple flag statements.

  • all—Trace with all flags enabled

  • configuration—Trace configuration events

  • hpl— Trace HPL logging

  • report— Trace report

  • source—Communicate with security log forwarder

• no-remote-trace—Set remote tracing as disabled.
