Hi, Great question from the CNCF Slack: What's the reason why we don't allow Exemplars for _count in Summary metrics?
Use case: Java's Micrometer provides a Summary with just a _count and a _sum as the default metric for HTTP services. The _count has the HTTP status code as a label, so these metrics are great for request rates and error rates (and for average latencies if you have nothing better). However, there's currently no way to have exemplars. It would be nice to have them, for example for investigating erroneous calls. If the _count was an explicit counter, and not part of a summary, Exemplars would be supported. What do you think? Any reason why Exemplars don't work in _count in Summaries? Would that be something we could consider supporting? Fabian -- You received this message because you are subscribed to the Google Groups "Prometheus Developers" group.
