traceoptions (dynamic-application)

Syntax

Hierarchy Level

Description

Configure dynamic application tracing options.

Note:

NOTE: Traceoptions does not differentiate between a logical system and tenant system, and can be configured under the root logical system.

Options

file

Trace file information

  • Values:

    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 as 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

    • Default: 3 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.

    • Range: 10 KB through 1 GB

    • Default: 128 KB

    world-readable|no-world-readable

    By default, the 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.
