Syntax
traceoptions {

flag flag;
level (all | error | info | notice | verbose | warning);
no-remote-trace;
}
Hierarchy Level
[edit system processes dhcp-service] [edit security dynamic-address]
Description
Define global tracing operations for extended DHCP local server and extended DHCP relay agent processes.
This statement replaces the deprecated traceoptions statements at the [edit forwarding-options dhcp-relay] and [edit system services dhcp-local-server] hierarchy
levels.
Traceoptions does not differentiate between a logical system and tenant system, and can be configured under the root logical system.
Options
file filename—Name of the file to receive the output of the tracing operation.
Enclose the name within quotation marks. All files are placed in the
directory /var/log.
files number—(Optional)
Maximum number of trace files to create before overwriting the oldest
one. If you specify a maximum number of files, you also must specify
a maximum file size with the size option.
Range: 2 through 1000
Default: 3 files
flag flag—Tracing
operation to perform. To specify more than one tracing operation,
include multiple flag statements:
all—Trace all events.auth—Trace authentication events.database—Trace database events.fwd—Trace firewall process events.general—Trace miscellaneous events.ha—Trace high availability-related events.era—Enables logging.interface—Trace interface operations.io—Trace I/O operations.liveness-detection—Trace liveness detection operations.packet—Trace packet and option decoding operations.performance—Trace performance measurement operations.profile—Trace profile operations.rpd—Trace routing protocol process events.rtsock—Trace routing socket operations.security-persistence—Trace security persistence events.session-db—Trace session database events.state—Trace changes in state.statistics—Trace baseline statistics.ui—Trace user interface operations.
level—Level of tracing to perform; also
known as severity level. The option you configure enables tracing
of events at that level and all higher (more restrictive) levels.
You can specify any of the following levels:
all—Match messages of all levels.error—Match error messages.info—Match informational messages.notice—Match notice messages about conditions requiring special handling.verbose—Match verbose messages. This is the lowest (least restrictive) severity level; when you configureverbose, messages at all higher levels are traced. Therefore, the result is the same as when you configureall.warning—Match warning messages.
Default:
error
match regular-expression—(Optional)
Refine the output to include lines that contain the regular expression.
no-remote-trace—Disable remote tracing.
no-world-readable—(Optional) Disable unrestricted
file access, allowing only the user root and users who
have the Junos OS maintenance permission to access the
trace files.
size maximum-file-size—(Optional)
Maximum size of each trace file. By default, the number entered is
treated as bytes. Alternatively, you can include a suffix to the number
to indicate kilobytes (maximum-file-sizek), megabytes (maximum-file-sizem), or gigabytes (maximum-file-sizeg). If you specify a maximum file size, you also must specify a maximum
number of trace files with the files option.
Range: 10,240 through 1,073,741,824
Default: 128 KB
world-readable—(Optional) Enable unrestricted
file access.
Required Privilege Level
trace—To view this statement in the configuration.
trace-control—To add this statement to the configuration.
