Metrics with Prometheus & Grafana

Metrics are numerical measurements that describe the state and performance of your applications and infrastructure. Think of them as vital signs for your software!

They provide valuable insights into:

• Performance: How fast is your app responding?
• Resource Usage: Is your server running out of memory?
• Availability: Is your service up and running for users?

By tracking metrics, you can understand trends, detect anomalies, and troubleshoot issues proactively.

Prometheus is an open-source monitoring system designed for reliability and scalability. It's a key tool in the cloud-native observability stack.

Its primary job is to:

• Scrape: Collect metrics from configured targets (like your applications).
• Store: Save these metrics in a time-series database.
• Query: Allow you to ask questions about the collected data.

Prometheus helps you get a clear picture of what's happening inside your Kubernetes cluster.
