Hi, Backend latency, round trip time is the major factor in each of the integrations. If it is taking more than the expected time to respond, there are many problems we are facing in production deployments. It is leading to - memory growths - cpu growths - system failures.
As of today, when it comes to troubleshooting these production systems, A major fact we need to collect is "How long it took a backend to respond to WSO2 server". At the moment, only out of the box configurable feature we have for this is , Observability. [1] . You may have noticed following note on the document. Note Observability is not enabled by default as it slightly impacts WSO2 API Manager's performance. If we are troubleshooting a single API failure, We should be able to troubleshoot without affecting other APIs. But if we enable observability, It is affecting the entire environment. More specifically, Customers are reluctant to enable it in production, due to performance hit. However, There are many other cases, where we have to find only the backend latency to troubleshoot issues and isolate. So, if we are trying to use observability for finding backend latency, It is an overkill. So, If we can implement a way to measure backend latency - For all APIs with specific to each of them - For a given api only - For all proxies/endpoint/connector etc with specific to each of them - For a given proxy/endpoint/connector etc only *without restarting the server*, That would add a huge advantage for customers, customer-success teams, every one when it comes to production deployment. So, Can we implement this kind of feature for upcoming releases of APIM and EI?
