Detailed Description

Writes simulation events to the console and, optionally, to a file.

Two modes are supported:

• Verbose mode prints every event (arrivals, assignments, completions, rejections and scaling) in color and copies them to the event file.
• Quiet mode prints only periodic status lines and information messages, so a 100,000-cycle run stays readable; the full summary is written at the end.

ANSI colors are used only when standard output is a terminal and color has not been disabled. Files never contain color codes.

bool Logger::openEventFile

(

const std::string &

path

)

log()

void Logger::log	(	LogCategory	category,
		unsigned long	cycle,
		const std::string &	source,
		const std::string &	message )

Logs one event.

Parameters

category	Event kind; Arrival/Assign/Complete/Reject/Discard/Scale events appear only in verbose mode.
cycle	Clock cycle of the event.
source	Name of the load balancer reporting the event.
message	Event text.
