traceoptions (SBC Configuration Process)

Syntax

Hierarchy Level

Release Information

Statement introduced in Junos OS Release 9.5.

Statement introduced in Junos OS Release 9.5 for EX Series switches.

Description

Configure trace options for the session border controller (SBC) process of the border signaling gateway (BSG).

Options

file filename—Name of the file that receives the output of the tracing operation. Enclose the name in quotation marks. All files are placed in the directory /var/log. You can include the following file options:

• 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 must also specify a maximum file size with the size option and a filename.

• match regex—(Optional) Refine the output to include lines that contain the regular expression.
• no-world-readable—(Optional) Disable unrestricted file access.

• 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 and filename.

• world-readable—(Optional) Enable unrestricted file access.

flag flag—Tracing operation to perform. To specify more than one tracing operation, include multiple flag statements. You can include the following flags:

• all trace-level—Trace all SBC process operations.
• common trace-level—Trace common events.
• configuration trace-level—Trace configuration events.
• device-monitor trace-level—Trace device monitor events.
• ipc trace-level—Trace IPC events.
• memory—pool trace-level—Trace memory pool events.

• trace-level—Trace level options are related to the severity of the event being traced. When you choose a trace level, messages at that level and higher levels are captured. Enter one of the following trace levels as the trace-level:

  • debug—Log all code flow of control.
  • error—Log failures with a short-term effect.
  • info—Log summary for normal operations, such as the policy decisions made for a call.
  • trace—Log program trace START and EXIT macros.
  • warning—Log failure recovery events or failure of an external entity.
• ui trace-level—Trace user interface operations.
