traceoptions

Syntax

Hierarchy Level

Description

Define tracing operations that track all routing protocol functionality in the routing device. You can also trace clock synchronization information using this command.

To specify more than one tracing operation, include multiple flag statements.

Note:

On Junos OS Evolved, traceoptions is disabled for op, event, and commit scripts. Instead, Junos OS Evolved enables default tracking and trace messages that are logged under /var/log/traces.

Default

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

Options

Values:

disable—(Optional) Disable the tracing operation. You can use this option to disable a single operation when you have defined a broad group of tracing operations, such as all.

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. 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. 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

flag flag—Tracing operation to perform. To specify more than one tracing operation, include multiple flag statements. These are the global routing protocol tracing options:

• all—All tracing operations

• condition-manager—Condition-manager events

• config-internal—Configuration internals

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

• graceful-restart—Graceful restart operations

• normal—All normal operations

• nsr-packet—Detailed trace information for BFD nonstop active routing only

• nsr-synchronization—Tracing operations for nonstop active routing

• nsr-synchronization—Nonstop active routing synchronization

• parse—Configuration parsing

• policy—Routing policy operations and actions

• regex-parse—Regular-expression parsing

• route—Routing table changes

• state—State transitions

• task—Interface transactions and processing

• timer—Timer usage

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

• Default: 128 KB

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

Required Privilege Level
