traceoptions (Protocols PCEP)

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.

Configure the Path Computation Element Protocol (PCEP) tracing options.

Options

filename

Name of the file to receive the output of the tracing operation. 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 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 must also include the size statement to specify the maximum file size.
flag

Area of path computation client process (pccd) to enable debugging output.

PCEP Tracing Flags

  • all—Trace all areas of PCCD code

  • pccd-config—All configuration parsing operations

  • pccd-core—PCCD core operations

  • pccd-functions—PCCD function entries and outs

  • pccd-main—PCCD main module

  • pccd-rpd—PCCD communication with RPD

  • pccd-ui—PCCD user interface handling
no-remote-trace

(Optional) Disable remote tracing options.
no-world-readable

(Optional) Allow only certain users to read 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 this 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: 1 MB.

    If you specify a maximum file size, you must also include the files statement to specify the maximum number of files.
world-readable

(Optional) Allow any user to read the log file.
