traceoptions (programmable-rpd)

 

Syntax

Hierarchy Level

Release Information

Statement introduced in Junos OS Release 16.2.

Description

Starts logging traces related to the programmable routing protocol process (prpd). The prpd provides public APIs to program routing systems, making it possible for users to directly access the APIs to customize, create and modify behavior of their network.

Use the traceoptions command, along with related show commands, to help debug client-server interactions, identify the flow of control, and detect errors, get client-level information and statistics.

You can filter traces according to the flag(s) you have enabled.

Default

If you do not include this statement, no tracing operations are performed.

Options

Values:

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

Range: 2 through 1000 files

Default: 10 files

no-world-readable—(Optional) Prevent any user 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. Note that if you specify a maximum file size, you also must specify a maximum number of trace files with the files option.

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

Range: 1024 to 4,294,967,295 bytes

Default: 128 KB

world-readable—(Optional) Allow any user to read the log file.

flag flag—Specifies the tracing operation to perform. To specify more than one tracing operation, include multiple flag statements. The options are:

  • all—All tracing operations.

  • client—Client events.

  • general—All normal operations and routing table changes (a combination of the normal and route trace operations).

  • normal—All normal operations.

  • policy—Routing policy operations and actions.

  • route—Routing table changes.

  • state—State transitions.

  • task—Interface transactions and processing.

  • timer—Timer usage.
