mans2singh commented on issue #9325: [FLINK-13542][metrics] Update datadog reporter to send metrics if the… URL: https://github.com/apache/flink/pull/9325#issuecomment-517944144 Hi @zentol I have an application that registers only specific metrics which are based on data and not know up front when the application starts (eg: an exception with its type). I saw that, if no exception for thrown and no metrics was registered for a long time, the datadog reporter was still periodically reporting empty series to the server. So, there might be other scenarios where there are no metrics registered and we can check to see if there are metrics before posting the data datadog. Also, do you think this check belongs to the client and not the reporter ? Let me know your thoughts. Thanks
