Output Metrics

MiSim supports the following output metrics. A csv table for each mertric is generated that contains data pairs of simulation time (column SimulationTime) and the assotiated value (column Value) .

#	Metric	File	Desciption
1	System Load	G[<LoadGeneratorName>]_[<TargetOperation>]_Load.csv	Load accumulated over 1 STU
2	Failed Requests	G[<LoadGeneratorName>]_[<TargetOperation>]_FailedRequests.csv	Failed Requests accumulated over 1 STU
3	Successful Requests	G[<LoadGeneratorName>]_[<TargetOperation>]_SuccessfulRequests.csv	Successful Requests accumulated over 1 STU
4	Failed Requests Global	GEN_ALL_FailedRequests.csv	Accumulation of failed requests over all load generators binned by 1 STU.
5	Successful Requests Global	GEN_ALL_SuccessfulRequests.csv	Accumulation of successful requests over all Load generators binned by 1 STU.
6	Global Response Times	R[All]ResponseTimes.csv	All measured responsetimes, independent of service.
7	Response Times	R[<EndpointName>]_ResponseTimes.csv	Response times simualted for the specific endpoint.
8	Instance Count	S[<ServiceName>]_InstanceCount.csv	Number of Instances of the respective service.
9	Load Distribution	S[<ServiceName>]_Load_Distribution.csv	List of instances that were chosen as load balancing target.
10	Service CPU Utilization	S[<ServiceName>]_CPUUtilization.csv	Average relative utilization of all instances of the service. (Probed every 0.1 STU by default)
11	Autoscaling Decision	AS[<servicename>]_Decision.csv	Holds the autoscaler decision as "UP","HOLD" and "DOWN"
12	Instance Changes	AS[<servicename>]_InstanceChange.csv	Number of started/stopped instances for a scaling decision
13	Measured Utilization	AS[<servicename>]_MeasuredUtilization.csv	Periodically measured Utilization by the autoscaler
14	Requests in System	I[<InstanceName>]_Requests_InSystem.csv	Number of Requests currently handled by an Instance.
15	Not Computed Requests	I[<InstanceName>]_Requests_NotComputed.csv	Number of Requests that still have a remaining computational demand for the instances' CPU.
16	Requests Waiting For Dependencies	I[<InstanceName>]_Requests_WaitingForDependencies.csv	Number of Requests still waiting for dependenies (data collection) to complete.
17	Internal Request Sends	I[<InstanceName>]_SendOff_Internal_Requests.csv	Number of open Dependencies. (One request may produces multiple dependencie requests.)
18	Instance State	I[<InstanceName>]_State.csv	State of the instance (Running, Shutting Down, Shut Down, ...)
19	Active Processes	C[_CPU]_ActiveProcesses.csv	The count of requests that are currently using active CPU time. Essentially active Threads.
20	Relative Utilization	C[_CPU]_RelativeUtiliization	A measure of how long the CPU will take to complete its active work and clear its queue.
21	Total Processes	C[_CPU]_TotalProcesses.csv	Count of requests currently assigend to be handled by the CPU. (Queuelenght + Active Processes)
22	Utilization	C[_CPU]_Utilization.csv	Percentage utilization of the CPU changes in n/CoreCount sized steps.
23	Binned/Avg. Utilization	C[_CPU]_UtilizationBinned.csv	Running Average over the utilization with window size of 0.5 STU (not modifyable yet).
24	Network Latency	NL_latency.csv	List of calculated Network latencies. Disabled by default.
25	Circuit Breaker State	CB[<CircuitBreakerName>]_[<CB_TargetService>].csv	Tupel of current (State, #SuccessFullRequests,#FailedRequests, FailureRate)
