Dropwizard指标可跟踪传入请求中的邮政编码

Question

I am working on an application that accepts incoming HTTP requests and contains the user's zip code. I would like to track each of the zip codes received using a metric such that it can be reported to Prometheus and graphed inside Grafana. It would not make sense to have a counter for every single zip code but I worry that a Gauge would not be appropriate and Grafana would miss some of the data between Prometheus scrapes. Any suggestions for how I could possibly accomplish this task? We do have logging but we need this information displayed in Grafana.

Answer 1

This is more a use case for logging than metrics given the cardinality.

This is a use case for a label, however Dropwizard doesn't support those. Thus if you're going to do this with Prometheus I'd suggest using the Java client with a Counter with a label for the zip code.
