Description

Trace options for the LMP protocol.

Options

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.

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.

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

Range: 2 through 1000
Default: 2 files

flag—Tracing operation to perform. To specify more than one tracing operation, include multiple flag statements.

• all—Trace all available operations
• init—Output from the initialization messages
• parse—Operation of the parser
• process—Operation of the general configuration
• route-socket—Operation of route socket events
• routing—Operation of the routing protocols
• server—Server processing operations
• show—show command servicing operations

flag-modifier—(Optional) Modifier for the tracing flag. You can specify one or more of these modifiers:

• detail—Provide detailed trace information
• receive—Packets being received
• send—Packets being transmitted

no-stamp—(Optional) Do not place timestamp information at the beginning of each line in the trace file. 
Default: If you omit this option, timestamp information is placed at the beginning of each line of tracing output.

no-world-readable—(Optional) Disallow any user to read the log file.

replace—(Optional) Replace an existing trace file if there is one. 
Default: If you do not include this option, tracing output is appended to an existing trace 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.

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: 1 MB

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