Is there a way to increment counter in prometheus for similar metrics scraped from pushgateway

Question

I have a running instance of pushgateway and prometheus. And prometheus is configured to scrape from pushgateway. I am able to push metrics from my .NET applications to pushgateway which are successfully scraped by my prometheus. But when a two similar metrics are pushed to pushgateway, they are considered as one by the prometheus and the count is always displayed as one. Is there a way to increment the prometheus count value when similar metrics are present in the pushgateway.

Answer 1

The metrics from the two apps should be separated by adding a label that will distinguish between them. This should solve your issue. Note that the pushgateway docs explicitly state that there should be no duplicate metrics.

Answer 2

Pushgateway is not designed to handle this situation. As the official doc said, Usually, the only valid use case for the Pushgateway is for capturing the outcome of a service-level batch job.

Or you can use this instead, which is a aggregating push gateway for Prometheus: https://github.com/weaveworks/prom-aggregation-gateway
