Latency The time it takes to service a request. It’s important to distinguish between the latency of successful requests and the latency of failed requests. For example, an HTTP 500 error triggered due to loss of connection to a database or other critical backend might be served very quickly; however, as an HTTP 500 error indicates a failed request, factoring 500s into your overall latency might result in misleading calculations. On the other hand, a slow error is even worse than a fast error! Therefore, it’s important to track error latency, as opposed to just filtering out errors.

C. Latency
In the context of Google's "Four Golden Signals," latency refers to the time it takes for an application to return a result or complete a request. It measures the delay between a request being made and the result being returned. If an organization is concerned about how long it takes for their application to respond, latency is the signal they should focus on.
