Monitor Azure Kubernetes with Prometheus and Grafana

Kubernetes, the popular container orchestration platform, can be effectively monitored using Prometheus and Grafana. Let's dive into how they work together:

  1. Prometheus:

    • Prometheus is a robust monitoring and alerting toolkit designed for cloud-native environments.
    • It collects metrics from various sources, including Kubernetes clusters, services, and applications.
    • Metrics are collected at regular intervals (default: 30 seconds) and include information about memory, CPU, disk performance, network I/O, and read/write rates.
    • By default, Prometheus retains metrics for up to 14 days, but this setting can be adjusted.
    • It exposes metrics via an API endpoint within your Kubernetes cluster.
    • Prometheus Operator simplifies the deployment and management of Prometheus and related components on Kubernetes.
    • Custom resource definitions (CRDs) define desired deployments for Prometheus, Alertmanager, Thanos Ruler, ServiceMonitor, PodMonitor, Probe, and PrometheusRule.
  2. Grafana:

    • Grafana is an analytics and visualization tool that works seamlessly with Prometheus.
    • It allows you to create custom charts, graphs, and alerts based on the metrics stored in the Prometheus database.
    • Developers and system administrators can use Grafana to explore and understand their metrics data.
    • Grafana dashboards provide interactive visualizations and insights into your Kubernetes cluster's performance.
    • You can set up alerts, run queries, and create custom visualizations using Prometheus as the data source.

Remember, Prometheus and Grafana work hand-in-hand to provide comprehensive monitoring and visualization capabilities for your Kubernetes environment. 🚀.
