traceoptions (Services Application Identification)
Statement introduced in Junos OS Release 10.2.
Configure tracing operations for application identification services.
file—Configure the trace file options.
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. By default, the name of the file is the name of the process being traced.
files number—Maximum number of trace files. When a trace file named trace-file reaches its maximum size, it is renamed to trace-file.0, then trace-file.1, and so on, until the maximum number of trace files is reached. The oldest archived file is overwritten.
If you specify a maximum number of files, you also must specify a maximum file size with the size option and a filename.
Range: 2 through 1000 files
Default: 10 files
match regular-expression—Refine the output to include lines that contain the regular expression.
size maximum-file-size—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 and a filename.
Syntax: x K to specify KB, x m to specify MB, or x g to specify GB
Range: 10 KB through 1 GB
Default: 128 KB
world-readable | no-world-readable—By default, log files can be accessed only by the user who configures the tracing operation. The world-readable option enables any user to read the file. To explicitly set the default behavior, use the no-world-readable option.
flag—Trace operation to perform. To specify more than one trace operation, include multiple flag statements.
all—Trace with all flags enabled.
level—Set the level of debugging the output option.
all—Match all levels.
error—Match error conditions.
