Syntax
Hierarchy Level
Release Information
Statement introduced before Junos OS Release 7.4.
file option added in Release 8.0.
Description
Configure Adaptive Services or Multiservices PIC tracing operations. The messages are output to /var/log/serviced.
Options
file 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.
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: 3 files
flag flag—Tracing operation to perform:
- all—Trace everything.
- command-queued—Trace command enqueue events.
- config—Trace configuration events.
- handshake—Trace handshake events.
- init—Trace initialization events.
- interfaces—Trace interface events.
- mib—Trace GGSN SNMP MIB events.
- removed-client—Trace client cleanup events.
- show—Trace CLI command servicing.
match regex—(Optional) Match output to a defined regular expression (regex).
Default: If you do not include this option, the trace operation output includes all lines relevant to the logged events.
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.
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 1 GB
Default: 128 KB
world-readable—(Optional) Allow any user to read the log file.
