What is a metric?

A metric is a numerical representation of data collected at regular intervals to monitor a system’s performance and behavior. In the context of Kubernetes, metrics can include data points such as CPU usage, memory consumption, network throughput, and the number of active Pods. These metrics help administrators understand how their applications and infrastructure perform and identify potential issues before they escalate.

Collecting metrics is crucial for several reasons:

• Proactive issue detection: Kubernetes administrators can identify and address potential problems before they impact users by monitoring key metrics
• Resource optimization: Metrics provide insights into resource usage, helping with optimizing resource allocation to improve efficiency and reduce costs
• Performance tuning: Regularly analyzing metrics allows application and system performance to be fine-tuned, ensuring the system runs smoothly
• Compliance and auditing...
