if you want to send the metrics to prometheus, https://github.com/clj-commons/iapetos is a nice client that works well and has some built in collectors as well (for mostly automatic collection of ring, jvm and exception metrics)

Nice! Of course metrics are not enough for a good observability story, but Prometheus is a really awesome tool :star-struck: It is so simple to setup and operate. And there are existing metric exporters for everything. It’s really great to monitor infrastructures especially. And also implementing your own metrics is super straight forward. Even without libaries, its text format is super simple 🙂

right on! As far as I've noticed in the infra world, prometheus is the most well documented one https://github.com/prometheus/docs/tree/master/content/docs and if I recall correctly, they are working on standardizing some of the formats like the metrics export
