Launch HN: Opstrace (YC S19) – open-source Datadog
We use [insert very large application performance monitoring tool here] for workloads running in [insert very, very large cloud provider here] and after examining our deployments, concluded that we were spending nearly $13k/mo for data transfer out expenditures because the monitoring agents have crazy aggressive defaults. Seems like running our own (which may be worthwhile) would alleviate anything like that.
