traceoptions (Chassis Cluster)

Syntax

Hierarchy Level

Description

Define chassis cluster redundancy process tracing operations.

A minimum traceoptions configuration must include both a target file and a flag. The target file determines where the trace output is recorded. The flag defines what type of data is collected.

Options

• file 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.

• files number —(Optional) 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 —(Optional) Refine the output to include lines that contain the regular expression.

• size maximum-file-size —(Optional) 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 filename.

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

• Range: 0 KB through 1 GB

• Default: 128 KB

• world-readable | no-world-readable—(Optional) 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 or operations to perform on chassis cluster redundancy processes. To specify more than one trace operation, include multiple flag statements.

  • all—Trace all the events

    • configuration—Trace configuration events

    • routing-socket—Trace logging of rtsock activity

    • snmp—Trace SNMP events

Required Privilege Level

trace—To view this statement in the configuration.

trace-control—To add this statement to the configuration.
