As a Prometheus developer I have seen a significant number of users who moved from Graphite because they found it doesn't scale and was far from rock solid for them, requiring regular manual care and feeding. By contrast Prometheus seems to be working pretty well for them at what we would consider to be a moderate load. I've heard similar about Nagios/Ichinga. Push vs. pull is largely not relevant for scaling (pull is slightly better in this regard, but only slightly). I've been involved with some extremely large scale monitoring systems, and the fact they were pull was never relevant to scaling them. May I ask what you consider to be a high level of scale? > It won't scale without a number of workarounds. There are very very few systems who won't scale without workarounds. That's the nature of scaling a non-trivial system.
