API Metrics

• API Uptime: Uptime is the continuous availability of an API, in order words, making sure the API is fully-functional without any outages.

• Requests Per Minute (RPM): Requests per minute is a performance metric that measures the number of requests the API will handle per minute.

• Latency: Latency or Network Latency is the time it takes for data or a request to go from one system to another system. It can be either between client & server or server & server(in the case of distributed services).

• Time To First Hello World: TTFHW is the time the user needs to make his first API transaction from the web page.

• Errors Per Minute: Errors per Minute (or error rate) is the number of API calls with failure responses

• Memory Usage: Memory usage helps you understand the amount of resource utilization; a high memory usage can be an indicator of servers overloaded.

• CPU Usage: Keeping track of the CPU is one of the important aspects of performance because high CPU usage can mean the server is overloaded, which can cause a severe bottleneck.
