As defined by the Google SRE initiative, the four golden signals of monitoring include the following metrics: Latency. Latency is the amount of time, or delay, a service takes to respond to a request. Traffic refers to the amount of user demand, or load, is on the system. Monitoring can provide a way to differentiate between.

Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). Two-way latency is often called round-trip time (RTT).
