I use a spring boot application with IntegrationFlows, with micrometer for exposing metrics. When the flow starts I see a metric with name spring_integration_send_seconds_count denoting processed data, after the flow is complete the same metric goes to zero as expected.
However, on application restart this metric is non-existent and this is causing issues with applying PromQL functions. The frequency of the flow running cannot be predicted.
I did read on https://docs.spring.io/spring-integration/docs/5.3.2.RELEASE/reference/html/system-management.html#configuring-metrics-capture but even with defaultCountsEnabled enabled it doesn't initialize the said metric.
Is it possible to reset the spring integration flow metric on the application restart without hardcoding it?
Spring Integration metrics are registered when they are first used - you have to send a message to a channel before the metric will appear.
