Before a new version of the application is deployed, the software is subject to a series of load tests that evaluate capacity and performance under a series of simulated traffic and application demands. These metrics are latency, traffic, errors, and saturation, all of which must be key considerations when curating user experience.

At Netflix, we periodically reevaluate our workloads to optimize utilization of available capacity. A quick canary test was free of errors and showed lower latency, which is expected given that our standard canary setup routes an equal amount of traffic to both the baseline running on 4xl and the canary on 12xl.

Reduced tail latencies In both our GRPC and DGS Framework services, GC pauses are a significant source of tail latencies. Each of these errors is a canceled request resulting in a retry so this reduction further reduces overall service traffic by this rate: Errors rates per second. There is no best garbage collector.

These signals ( latency, traffic, errors, and saturation ) provide a solid means of proactively monitoring operative systems via SLOs and tracking business success. SLOs, as a measure of service quality, can track the related availability, reliability, and performance. This is what Dynatrace captures as response time.
