7.4 Monitoring and data retrieval

There are three methods for obtaining monitored data about arrivals, resources and attributes. They can be applied to a single simulation environment or to a list of environments, and the returning object is always a data frame.

• get_mon_arrivals(): Returns timing information per arrival: name of the arrival, start_time, end_time, activity_time (time not spent in resource queues) and a flag, finished, that indicates whether the arrival exhausted its activities (or was rejected). By default, this information is referred to the arrivals’ entire lifetime, but it may be obtained on a per-resource basis by specifying per_resource = TRUE.
• get_mon_resources(): Returns state changes in resources.
• get_mon_attributes(): Returns state changes in attributes.
