Information about the price category, the [[Metis_Smart_Modeling_-_Models|models]] or the rules is displayed. It is possible to see the details about a rule. For example, select the rule “Configure basic hardware based on CPU choice (low).”

Preview the rule by either clicking on the “Rule Preview” button or by double clicking on the selected rule.

The rule window opens showing details about the rule. Close this window.

The user can also set a “watchdog” to a position or a [[Metis_Smart_Modeling_-_Variables|variable]]. A “watchdog” can be considered as a breakpoint. When executing the [[Metis_Smart_Modeling_-_Models|model]] using the “Start” and “Next Break point” buttons, the process continues until the “watchdog” position or [[Metis_Smart_Modeling_-_Variables|variable]] is encountered.

Click on the “Start” button to execute the [[Metis_Smart_Modeling_-_Models|model]]. Click on the next button to execute the rules of the [[Metis_Smart_Modeling_-_Models|model]], step by step.  

The result values associated with the execution of the rules are displayed in the table “output values and watchdogs” below.

The debugger tool included in Metis Smart Modeling allows to set breakpoints throughout the execution of an imported Metis Smart Quotes environment. Those breakpoints can be used to stop a step-by-step execution at a specific place or time of the offer. For example at the beginning of one of the [[Metis_Smart_Modeling_-_Systems|systems]] included in the offer or when a specific [[Metis_Smart_Modeling_-_Variables|variable]] changes value. This can be very useful to pinpoint a problem in a [[Metis_Smart_Modeling_-_Models|model]] based on certain values.

In the Metis Smart Modeling debugger window, the top table shows the complete content of the imported environment (Offer, [[Metis_Smart_Modeling_-_Systems|system]] and applications, [[Metis_Smart_Modeling_-_Models|models]] used, [[Metis_Smart_Modeling_-_Group_of_Rules|group of rules]] and rules which are executed). Each line listed in the table represents one of the steps of the execution process. Break-point can be set of any of those lines simply by clicking once the leftmost "grayed" column of the table. this add a small red dot to the line showing the user that the step-by-step will stop before executing this line in the process.

To remove a break-point from the execution list, click of the small red dot in from of the line. The execution will then execute until the next one or the end of the list.

Additionally to stopping the execution of the imported environment at a specific place or moment of the execution, Metis Smart Modeling also allows to set break-point on [[Metis_Smart_Modeling_-_Variables|variable]], positions and [[Metis_Smart_Modeling_-_Variables#What_is_a_group_of_items.3F|group of items]]. This can be done by using the "output Values & Watchdogs" table. Simply click in the leftmost column of the item which should stop the execution. Metis Smart modeling will then pause the execution process when the value stored with the item changes due to a rule. By looking at the execution list, the specific operation which applied this change can be viewed.

| Breakpoints on [[Metis_Smart_Modeling_-_Variables|variable]] or positions are very helpful to test and verify that it is not modified when not required.

Within the list of of "Output Values & Watchdogs" are only shown the [[Metis_Smart_Modeling_-_Variables|variables]], positions and groups of items which are either used as an output or an add-on to any rule included in the environment. In order to work on [[Metis_Smart_Modeling_-_Variables|variables]] or positions which could be used as inputs or filters, Metis Smart Modeling allows the user define so called watchdogs. They are [[Metis_Smart_Modeling_-_Variables|variables]], positions or [[Metis_Smart_Modeling_-_Attributes|attributes]] which are not listed in the previously named table but which could be used in rules as either input values or filters.

In order to define a new watchdog within the debugger, click on the ADD button [[File:MetisSmartModelingAddButton.PNG|link=]] located on the right of the "Output Values & Watchdogs" table. A window opens up which allows to select the position, the [[Metis_Smart_Modeling_-_Variables|variable]] (or [[Metis_Smart_Modeling_-_Variables|group of items]]) or [[Metis_Smart_Modeling_-_Attributes|attribute]] to be used as a watchdog. Select the appropriate one and validate in order for it to be listed in the table. Once done, move to the XX column of the inserted element and set the value for which it should be tested. When the execution process starts, and at each step, the watchdog will be tested against the value provided. If equal, then the execution pauses.

In order to remove a watchdog from the list, use the MINUS button on the right of the table.

| Watchdogs on [[Metis_Smart_Modeling_-_Variables|variable]] or positions are very helpful to test and verify that a given [[Metis_Smart_Modeling_-_Variables|variable]] or position is not modified prior to being used as an input to another rule.
