Value is wrong from api servcie about prometheus-adapter HOT 3 CLOSED

You'll have to provide more information. What object are you fetching the metric on? I'd guess, however, that the value is being aggregated over other labels. Can you post the full set of labels on the series? If you query prometheus for sum(your_metric_name{the_type="some-name"}) by (the_type), what gets returned?

I have found the root cause. In my application, I created serval pods and services. Each pod had a metric called worker_queue_length_percentage. And there could be serval services that selected a same pod. For each service I also created a corresponding service monitor. So in prometheus there were serval records for a pod, with each service having one record. And it seemed that k8s-prometheus-adapter would sum them up for the metric of one pod.

After finding the root cause, I have fixed this issue.

yep, that would do it. As discussed in the documentation, the adapter sums over all labels besides the requested resource's label: https://github.com/DirectXMan12/k8s-prometheus-adapter/blob/master/docs/format.md#L38-L40
