I'm using Dropwizard Metrics to expose the metrics of an HikariCP connection pool. These metrics are then piped to Prometheus using its jmx_exporter.
One of the exposed metrics is the number of active connections, which, as stated on the HikariCP wiki, one of the exposed metrics is the number of active connections in the pool, which is kept as a CachedGauge. When I read the metrics, I see both a ..._pool_activeconnections_value and a ..._pool_activeconnections_number.
According to what I could find on Dropwizard Metrics' documentation, a gauge only exposes a value. What is the other metric ?
