HealthCheckAPI: monitoramento de APIs gRPC.

Abstract

Launched by Google in 2016, gRPC is a framework based on RPC (Remote Procedure Call) for creating APIs that has become increasingly popular among companies, startups and open-source projects. As it is a new technology, monitoring, observability and maintenance tools that support gRPC are quite scarce in the software development community. Furthermore, the few solutions available are often difficult to configure or do not produce desired metrics, such as call execution latency. Given this context, the purpose of this work is to develop HealthCheckAPI, a gRPC API monitoring platform. This application is capable of monitoring all endpoints available through the API through periodic calls to the service, obtaining availability and response time information, in addition to allowing the user to configure validations for the message returned by the API, as is done on the Assertible and Checkly platforms which are for monitoring REST APIs only.
