I'm using kuberenetes for our application. It can have max 8 pods. I've used manual instrumentation for taking the input tps value as a gauge metrics and each pod is exporting via http exporter every second. But once we're getting the graph for TPS VS time, its showing values of only 1 pod per second. I need to know the total TPS value of n pods per second and not just one pod. I tried SUM aggregation but it's not giving me correct value. Can someone support?
