These signals ( latency, traffic, errors, and saturation ) provide a solid means of proactively monitoring operative systems via SLOs and tracking business success. An excellent way to establish an SLO based on latency is to have a certain percentage of all service requests returned within a selected time frame of, for example, 300 ms.
