StackImpact is a set of profilers, which continuously sample production applications at low-overhead. The result is line-of-code precision, not just application-level metrics. I think it doesn't really compare to monitoring tools such as DataDog. However, it also sends metrics as well (cpu, memory, GC). (Disclaimer: I work at StackImpact)
