> Prometheus alternative

Well... if size of the executable is really a concern, perhaps Victoria Metrics is worth considering; my amd64 executable is about 17MiB in size.

Everyone should consider Victoria Metrics anyway. It scales better performance wise, and they broke out components to improve scalability (vmagent, vmalert, etc) when Prometheus was just one huge process that did all the things. The two work closely together, and even did a good talk together about the differences.

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.

Not only that, we were able to reduce the total virtual machine ram where our monitoring was hosted by half and storage is more efficient too I think when we switched to victoriametrics.
