Release Information

Statement introduced in Junos OS Release 7.5.

Statement introduced in Junos OS Release 9.0 for EX Series switches.

Statement introduced in Junos OS Release 13.2X51-D10 for QFX Series switches.

Description

Define tracing operations for event policies.

Default

If you do not include this statement, no event-policy-specific tracing operations are performed.

Options

file filenameName of the file to receive the output of the tracing operation. All files are placed in the directory /var/log. By default, event policy process tracing output is placed in the file eventd. If you include the file statement, you must specify a filename. To retain the default, you can specify eventd as the filename.

Default: /var/log/eventd

files number(Optional) Maximum number of trace files. When a trace file named trace-file reaches its maximum size, it is renamed and compressed to trace-file.0.gz. When trace-file again reaches its maximum size, trace-file.0.gz is renamed trace-file.1.gz and trace-file is renamed and compressed to trace-file.0.gz. 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 also must specify a maximum file size with the size option and a filename.

Range: 2 through 1000

Default: 3 files

flag flagTracing operation to perform. To specify more than one tracing operation, include multiple flag statements. You can include the following flags:
  • all—Log all operations

  • configuration—Log reading of configuration at the [edit event-options] hierarchy level

  • events—Log eventd processing

  • database—Log events involving storage and retrieval in events database

  • server—Log communication with processes that are generating events

  • timer-events—Log internally generated events

match regular-expression(Optional) Refine the output to include lines that contain the regular expression.
no-world-readableRestrict file access to owner. This is the default.
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 and compressed to trace-file.0.gz. When the trace-file again reaches its maximum size, trace-file.0.gz is renamed trace-file.1.gz and trace-file is renamed and compressed to trace-file.0.gz. 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.

Syntax: size to specify bytes, sizek to specify KB, sizem to specify MB, or sizeg to specify GB

Range: 10 KB through 1 GB

Default: 128 KB

world-readable(Optional) Enable unrestricted file access.
