Monitoring and Logging Solution for Kubernetes Cluster

This document outlines the steps to set up a comprehensive monitoring and logging solution for a Kubernetes cluster without using Helm charts. The solution involves deploying a sample application, configuring Prometheus and Grafana for monitoring, and setting up an ELK (Elasticsearch, Logstash, Kibana) stack for log collection and visualization.

1. Prerequisites

  • A functioning Kubernetes cluster
  • kubectl command-line tool installed and configured

2. Deployment

Deploy a sample application on the Kubernetes cluster using your preferred deployment method.

3. Monitoring Setup

3.1 Prometheus

  1. Create a Prometheus deployment manifest and apply it to the cluster.
  2. Configure Prometheus to scrape the sample application's metrics by specifying the appropriate service endpoints.

3.2 Grafana

  1. Create a Grafana deployment manifest and apply it to the cluster.
  2. Access Grafana's web interface, configure Prometheus as a data source, and import predefined dashboards or create custom ones.

4. Logging Setup

4.1 Elasticsearch

  1. Deploy an Elasticsearch cluster using a deployment manifest.
  2. Configure Elasticsearch for data storage.

4.2 Logstash

  1. Create a Logstash deployment manifest and apply it to the cluster.
  2. Configure Logstash to parse and forward logs from the sample application to Elasticsearch.

4.3 Kibana

  1. Deploy Kibana using a deployment manifest.
  2. Access Kibana's web interface and set up an index pattern for the application logs.

5. Dashboard and Visualizations

5.1 Grafana Dashboard

  1. Create a Grafana dashboard manifest and apply it to the cluster.
  2. Configure panels and graphs in the dashboard to monitor key metrics over time.

5.2 Kibana Visualization

  1. Access Kibana's web interface and create visualizations that highlight error logs over time.
