traceoptions (Event Options)

Syntax (Junos OS)

Hierarchy Level

Description

Define tracing operations for event policies on devices running Junos OS.

Junos OS Evolved uses a different tracing infrastructure, which collects trace data from all applications on all nodes by default. For more information, see Trace Event Policy Processing on Devices Running Junos OS Evolved.

Default

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

Options

file `filename`	Name 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 `flag`	Tracing 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-readable	Restrict 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, `size`k to specify KB, `size`m to specify MB, or `size`g to specify GB Range: 10 KB through 1 GB Default: 128 KB
world-readable	(Optional) Enable unrestricted file access.
