traceoptions (Services Redundancy Daemon)

Syntax

Hierarchy Level

Description

CAUTION:

Enabling tracing can adversely impact scale and performance and may increase security risk. We strongly recommend using the trace, tracing, or traceoptions commands only under the guidance of a JTAC support engineer. After collecting the debug information, immediately disable tracing to minimize risk and restore normal system performance.

Specify the level of redundancy system events to be traced.

Options

file file-name

Name of the file to receive the output of the tracing operation.
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.

  • Range: 2 through 1000 files

  • Default: 3 files
flag flag

Specify which operations are to be traced. To specify more than one operation, include multiple flag statements.

  • all—Trace everything.

  • config—Trace services redundancy configuration events.

  • connect—Trace services redundancy ipc events.

  • error—Trace services redundancy errors.

  • database—Trace services database events.

  • normal—Trace normal events.

  • opcmd—Trace services redundancy opcmd events.

  • parse—Trace services redundancy parse events.

  • route—Trace services redundancy route events.

  • snmp—Trace services redundancy snmp events.

  • state—Trace services redundancy set state-machine.

  • switchover—Trace switchover events.

  • system—Trace services redundancy system events.
level

Use the specified level of tracing. You can specify any of the following levels:

  • all—Match all levels.

  • critical—Match critical conditions.

  • error—Match error conditions.

  • info—Match informational messages

  • notice—Match conditions that must be handled specially.

  • verbose—Match verbose messages.

  • warning—Match warning messages.
no-remote-trace

(Optional) Disable remote tracing.
no-world-readable

(Optional) Disable unrestricted file access.
size size

(Optional) Use the maximum size of each trace file, in kilobytes (KB) or megabytes (MB). 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 number of files, you must also specify a maximum file size with the size option.

  • Syntax: xk to specify KB, xm to specify MB, or xg to specify GB.

  • Range: 10,240 through 1,073,741,824 bytes.

  • Default: 128 KB
word-readable

(Optional) Enable unrestricted file access.
