FAQPage Schema

How do I build a custom cloud cost analysis plugin for FinFocus?▼

To build a FinFocus cost plugin, use the pluginsdk to scaffold the project, implement CostSourceService methods like GetProjectedCost, and handle gRPC communication for data exchange. This extends FinFocus with new cloud provider support.

How does gRPC communication work between FinFocus core and plugin binaries?▼

FinFocus plugins use gRPC to communicate with the core application. Your custom plugin binary acts as a gRPC server implementing the CostSourceService, allowing FinFocus core to invoke methods like GetActualCost and GetRecommendations over the protocol.

What is the best way to structure a new FinFocus plugin project?▼

Structure a new FinFocus plugin by scaffolding the project with the pluginsdk. You need to implement the CostSourceService interface to define how GetProjectedCost, GetActualCost, and GetRecommendations fetch and format cost data.

Can I add support for a niche cloud provider not natively supported by FinFocus?▼

Yes, you can add support for a niche cloud provider by developing a custom plugin. Use this Skill to learn plugin scaffolding and implement the required CostSourceService methods to fetch and format your specific provider's cost data.

What testing strategies are recommended for FinFocus plugin development?▼

Testing FinFocus plugins involves validating your CostSourceService implementation and gRPC communication patterns. You must ensure methods like GetProjectedCost and GetRecommendations return accurate cost calculation logic before deploying the plugin binary.
