A simple spring boot 3.x app highlighting how we can add our own tags in controller metrics. This will override the default tags provided by Spring Framework.
I'm trying to do observability for cassandra in springboot. I have integrated with micrometer and able to push low cardinality metrics of cassandra db. But, unable to push high cardinality metrics to prometheus.
How can I customize the ObservationConvention interface to fetch high cardinality metrics via springboot application.I have followed this spring documentation link.
