Execution Monitor monitors the model execution progress status and allows execution of debugging scripts. The execution stats include the execution status, estimation of execution progress % and model coverage.

Stop condition section lists the stop condition(s) set for the model execution. Model execution is completed when any of the stop conditions evaluates to true:

• Transitions - transition coverage in percentage, a transition is considered covered when it has been traversed Traversals Required times set in Transition Properties
• Traversals - number of transition traversals, each time a transition is traversed is counted one traversal
• Elapse Time - elapse time in minutes
• Requirements - requirement coverage in percentage
• Test Paths - number of test paths (test cases)

If no stop conditions are specified, the default stop condition is Transitions 100% or when all test paths generated by the selected sequencer have been exhausted.

• Status - model execution status, STARTED, PAUSED, ENDED or ERRORED.
• Virtual Users - number of virtual users (threads) specified in Execution Setting.
• Running - active virtual users (threads)
• Start Time - model execution start date and time
• Elapse Time - model execution elapse time
• End Time - date and time when model execution completed or estimated date and time when the model execution will complete
• Progress - model execution completion in percentage
• JVM Memory - amount of JVM heap memory in use and total amount of memory available (allocated). This percentage will fluctuate up and down and occasionally up to 100%. This is normal as long as the percentage does not stay on 90+% at all time.

Debug Expression allows you to run scripts while the model is executing or execution is paused. Script will be executed on a randomly selected virtual user (thread) if more than one is running.

The results from the script execution are displayed in JSON.

Be aware that if some of functions in $SYS may depend on the context of the thread. For example $SYS.getCurState() reports the current state. While model execution is paused, it may not have the state context established yet.
