Troubleshooting What-if Simulation issues
When you perform a What-if Simulation to simulate the growth of resources, the simulation might fail with error or warning messages.
Issues displayed on UI
The UI displays warnings related to missing data or incomplete simulation.
Use the following information to identify and resolve issues:
Message | Explanation | Solution | Displayed in... |
|---|---|---|---|
| From the selected deployments, one or more deployments are not included in the simulation. This message appears at the top of the Simulation page. | Click Learn more to view the errors associated with each deployment. It could be one of the errors listed in the rows below. The warning message displays the name of the deployment that helps you identify the deployment which is resulting in an error. | What-if simulation for deployments |
| You do not have the permission to access the requested entity. The following permissions are required to access a What-if Simulation:
| Contact your administrator to request for access. For details, see Configuring authorization profiles. | What-if simulation for deployments What-if simulation for a business service |
| Data about the number of pods that are running in a deployment is mandatory to generate a simulation. When this data is not available for the last 7 days, the deployment is excluded from the simulation. |
You can also create a quick analysis with the 'last 7 days' filter to check whether the metric has data for the last 7 days. | What-if simulation for deployments |
| Data for one or more of the required metrics is not available for simulation. |

| This message is displayed due to intermediate errors. | Run the simulation again. If the issue persists, contact BMC Support. | What-if simulation for deployments What-if simulation for a business service |
| A What-if Simulation can simulate growth only for the Kubernetes deployments. You cannot simulate for any other entity. When you try to simulate using a system identifier of an incorrect entity, this warning is displayed. | Exclude the deployment from the simulation and run the simulation again. | What-if simulation for deployments |
| Data is not available to complete the simulation. | Check whether the ETL has failed to collect data. Check the ETL logs for troubleshooting. | What-if simulation for deployments |
| Resizing request for the same pool and same date is already available. | Edit the custom resizing request and select the different date. | What-if simulation for a business service |
Error codes displayed on APIs
Error code | Explanation | Solution |
|---|---|---|
OPT_SIMULATION_0 | Request validation error | |
OPT_SIMULATION_2 | An error occurred invoking the catalog service | Check related logs |
OPT_SIMULATION_3 | An error occurred invoking the analysis service | Check related logs |
OPT_SIMULATION_4 | An error occurred invoking the forecast service | Check related logs |
OPT_SIMULATION_5 | Simulation not found | Check if the simulation ID is valid and exists in the database |
OPT_SIMULATION_6 | An error occurred saving the simulation into the database | Check optsimulation logs |
OPT_SIMULATION_7 | Simulation not executed as a warning has been detected | Check optsimulation logs |
OPT_SIMULATION_8 | Unsupported Input has been detected | Check optsimulation logs |
OPT_SIMULATION_9 | CFS produced no results for this business service | If it is a new business service, wait for the business service to be processed automatically, otherwise it means there is no correlation between business driver and service pools included in this business service. |
OPT_SIMULATION_10 | Simulation produced no results for this business service | It might be due to missing business driver metrics or other data dependent issues that made the simulation impossible. |
