Latency

Latency is the time it takes for a request to travel through a system. Latency metrics are crucial for understanding service performance, especially in real-time applications.

Error Rate

This metric monitors the frequency of errors occurring in the system. It can include application errors, infrastructure failures, and network errors. It is essential for ensuring service reliability.

Throughput

Throughput measures the amount of data processed in a given period. This metric is fundamental for assessing the system’s ability to handle workload.

Availability

Availability refers to the time a service is operational and accessible to users. High availability is critical for customer satisfaction and business continuity.

Resource Utilization

Monitors the use of resources such as CPU, memory, and disk. These metrics help understand whether resources are being used efficiently or if there is a need for scalability.

Response Time

Response time measures the average time the system takes to respond to a request. It is a crucial metric for evaluating user experience.
