REST Endpoint: GET: https://rason.net/odata/solvelog

A REST API endpoint that returns the log of solve requests for the requesting user. Fields returned are listed below. Note that a single model is a decision flow with one stage.

• ResourceID: Resource ID of the model instance. The ResourceID is not updated in the case of scheduled models.
• SeqNumber: If the model is a scheduled model, this field allows multiple runs of the same model with the same ResourceID.
• SolverUserID: Requesting User ID
• Name: Name of submitter.
• Email: Email of submitter
• ModelName: Model name
• ModelVersion: Resource ID of the parent origin/version model, if any.
• SolveTimeStamp: Complete decision flow solve timestamp.
• SolveTime: The complete decision flow solve time in seconds.
• Origin: Submitted user IP address.
• SubmittedBy: Submitted application type.
• StatusCode*: Solver final result code for the decision flow.

  StatusMessage*: Solver final result code text message for the decision flow. *See the description for GET rason.net/api/model/{nameorid}/result or the Solver Result Messages chapter within the RASON Reference Guide for detailed information on each possible status code and message.

• SolveType: Operation performed. See the list below for all solve types.
• NumStages: Total number of stages in the decision flow.
• NumAttemptedStages: The number of stages attempted, in the decision flow. This value will be equal to NumSucceededStages if solving the entire flow.
• NumSucceededStages: The number of stages that succeeded in the decision flow.
• ManagedModel: If True, this field indicates that the solved model is a managed model. A managed model is a model stored on the RASON.com server and solved with an asynchronous endpoints. (Solves triggered by Analytic Solver Cloud are not included.)
• CommonSolveType: Endpoint used to solve the model: Unknown, Optimization (\optimize), Simulation (\simulate), Decision (\decision), Datamining (\datamine), Solve (\solve), IISFind (infeasibility report), Diagnosis (\diagnose) or Analysis.
• CommonStatusCode: Status of the decision flow: Success, Stopped, Invalid or Error.
• InstanceType: Displays the model instance type: Unknown, Optimization, Simulation, Calculation, Datamining, Flow.
• ModelKind: Filters on the ModelKind field: ModelKind = Excel (posted Excel model), RASON (RASON models) or LP/MPS models.
• Stages: Log returned for all stages in the decision flow. (A single model is a decision flow with one stage.)
• SeqNumber: If running a scheduled model
• Name: Standalone model or stage name.
• StageID: Used to locate the stage model. If the decision flow is “in-line, this value will be the same as the enclosing flow. If a reusable model, this value will be the ResourceID of the reusable model.
• Type: The model type: optimization, simulation, decision, or data science.
• Kind: Filters on the ModelKind field: ModelKind = Excel (posted Excel model), RASON (RASON model) or LPMPS.
• Attempted: True if a solve was attempted for this stage; false otherwise.
• Succeeded: True if the solve of this stage was completed; false otherwise.
• Skipped: True if this stage was skipped in the decision flow solve. A skipped stage could be due to a failure or reusing previously available results based on Recency.
• StatusCode: Final status of solve. See the description for GET rason.net/api/model/{nameorid}/result for a list of possible result codes.
• StatusMessage: Final status of solve. See the Solver Result Messages chapter within the RASON Reference Guide for information on each result.
• SolveTime: The time (in seconds) to solve this stage.
• SolveTimestamp: The timestamp of the solve for this stage.
• Optimization: null, if the stage does not contain an optimization model

  [

  • ResourceID: Resource ID of the model instance
  • SeqNumber: If a scheduled model, this is the sequence number of the model instance.
  • NumVariables: The number of variables in the optimization stage model.
  • NumIntegerVariables: The number of integer variables in the optimization stage model.
  • NumFunctions: Number of constraints plus the objective in the optimization stage model.
  • Type: Optimization type: LP (linear problem), QP (quadratic problem), QCP (quadratically constrained problem), CVX (convex), NLP (nonlinear problem) or NSP (nonsmooth problem).

  ]

• Simulation: null, if the stage does not contain a simulation model

  [

  • ResourceID: Resource ID of the model instance.
  • SeqNumber: If a scheduled model, this is the sequence number of the model instance.
  • NumUncertainVariables: Total number of uncertain variables in the simulation model.
  • NumUncertain Functions: Total number of uncertain functions in the simulation model.

  ]

• Calculation: null, if the stage does not contain a calculation, or decision, model

  [

  • ResourceID: Resource ID of the model instance.
  • SeqNumber: If a scheduled model, this is the sequence number of the model instance.
  • NumObservations: Number of observations in the decision model.

  ]

• DataMining: null, if the stage does not contain a data science or forecasting model

  [

  • ResourceID: Resource ID of the model instance.
  • SeqNumber: If a scheduled model, this is the sequence number of the model instance.
  • NumTrainingRows: Number of rows in the training data.
  • Number of columns in the training data.
  • Type of data science algorithm: classification, regression, transformation, featureSelection, timeSeries, clustering, textMining, bigdata, affinityAnalysis.
  • Algorithm: Data science algorithm.
