Queue Stats Collector Block :: SAS(R) Simulation Studio 12.1: User's Guide

Description

The Queue Stats Collector block accumulates statistics generated by blocks in your model that implement the QueueStatsGenerator interface. In the properties dialog box associated with the Queue Stats Collector block, you can select from a list of available (QueueStatsGenerator) blocks the ones from which you want to collect statistics.

By default, statistics are gathered from the selected blocks at the end of each design point replication run. Options are provided to collect statistics on a continuous basis (whenever the statistics change) or to force an instantaneous update of the statistics.

The Queue Stats Collector block uses its data collection facility to store values it collects. The statistics can be saved to a SAS data set or JMP table. The statistics are stored in a SimDataModel, which can be accessed through the block’s OutData port. To visualize the statistics, you can connect a display block (such as the Bar Chart block) to the OutData port. Any block connected to the OutData port is automatically notified when the statistics in the SimDataModel are modified.

Fixed Ports

OutData: Output port for the latest updated SimDataModel that contains the statistics held by the Queue Stats Collector block.
ResultLocation: Output text port for the pathname of a folder that contains the output data set, if the Queue Stats Collector block is configured to save its statistics.

Attributes Dialog Box Controls

Add: Adds the selected blocks to the list of blocks from which to collect statistics.
Remove: Removes the selected blocks from the list of blocks from which to collect statistics.
Continuous Collection: Turns on or off statistics collection whenever a monitored block changes state.
Now: Forces the Queue Stats Collector block to attempt an immediate collection of any statistics.

Save Dialog Box Controls

Automatic Save: Turns on or off automatic saving of any collected statistics at the end of each design point replication run. If automatic saving is turned on, statistics are saved to a file with the base filename specified in the Base File Name field. Simulation Studio automatically determines the pathname of the folder for this file based on the pathname of the folder that contains your saved project. If the Submit to Remote SAS Workspace Server option is selected, any collected statistics are saved to a file on a remote SAS server. Simulation Studio automatically determines the pathname of the folder for this file on the remote SAS server by using the Default File Path specified in the Simulation Studio Configuration dialog box.
Save Now: Forces the Queue Stats Collector block to attempt an immediate save of any collected statistics. Statistics are saved to the same location as when automatic saving is turned on.
Location: Displays the pathname of the folder for the file in which to save any collected statistics.
Base File Name: Specifies the base filename for the SAS data set or JMP table that is used to save any collected statistics. This name is the prefix of the actual filename. The zero-based index of the design point and the zero-based index of the replication number are added as suffixes to the filename, separated by underscore characters. For example, the statistics for the first replication of the first design point are saved in a file named BaseFileName_0_0, and the statistics for the second replication of the first design point are saved in a file named BaseFileName_0_1.
