traceoptions (High Availability)

Syntax

Hierarchy Level

Description

CAUTION:

Enabling tracing can adversely impact scale and performance and may increase security risk. We strongly recommend using the trace, tracing, or traceoptions commands only under the guidance of a JTAC support engineer. After collecting the debug information, immediately disable tracing to minimize risk and restore normal system performance.

Set Multinode High Availability traceoptions

Options

file filename—Name of the file to receive the output of the tracing operation. Enclose the name within quotation marks

file name—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. We recommend that you place global routing protocol tracing output in the file routing-log.

files number—(Optional) Maximum number of trace files. When a trace file named trace-file reaches its maximum size, it is renamed trace-file.0, then trace-file.1, and so on, until the maximum number of trace files is reached. Then the oldest trace file is overwritten.

  • Range: 2 through 1000 files

  • Default: 2 files

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

no-world-readable—Restrict users from reading the log file.

size 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.

  • Syntax: xk to specify KB, xm to specify MB, or xg to specify GB

  • Range: 10 KB through the maximum file size supported on your system

  • Default: 128 KB

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

world-readable—Allow users to read the log file.

level—Set a level of tracing.

  • Values:

    • alert—Match alert conditions

    • all—Match all levels

    • critical—Match critical conditions

    • debug—Match debug messages

    • emergency—Match emergency conditions

    • error—Match error conditions

    • info—Match informational messages

    • notice—Match notice level messages

    • warning—Match warning messages
no-remote-trace—Disable remote tracing.
