I love Prometheus because the (OpenMetrics) data protocol is so darn simple and easy to grok. You can do things like take an arbitrary data source, pipe it through awk and curl, and get it into prometheus metrics via remotewrite. You can also easily write your own /metrics endpoint in your favorite language.

VictoriaMetrics sweetens the deal by offering a solution to long-term storage and more flexible service architecture without leaving the simple and highly interopable Prometheus ecosystem.
