Description

To enhance our Kubernetes cluster's observability and responsiveness, we aim to implement the Kube Prometheus Stack. This addition will offer a robust solution to monitor Kubernetes logs and provide insightful visualization of key metrics, leading to improved incident detection and overall system performance.

Features to Implement:

Prometheus Operator:

• Provision the Prometheus Operator, streamlining the deployment and configuration of Prometheus, Alertmanager, and other monitoring components.
• Set up the operator with the necessary RBAC permissions for seamless operations.

Service Monitors:

• Deploy ServiceMonitors to enable automatic service discovery and monitoring within the cluster.
• Configure ServiceMonitors to effectively scrape relevant metrics from our applications and services.

Grafana Integration:

• Integrate Grafana to visualize the metrics being collected by Prometheus.
• Create or import dashboards specifically designed for Kubernetes monitoring.

Alertmanager Configuration:

• Set up and configure Alertmanager to manage and route alerts generated by Prometheus.
• Ensure Alertmanager is integrated with external channels such as Slack, PagerDuty, or email for real-time alert notifications.

Acceptance Criteria

• Prometheus is actively and correctly scraping metrics from all targeted services in the Kubernetes cluster.
• Grafana showcases updated dashboards that reflect real-time metrics.
• Alertmanager effectively triggers and sends alerts to the designated channels when predefined thresholds are crossed.

Additional Notes

• It's imperative to secure monitoring endpoints, with Grafana being a priority, using proper authentication measures.
• Configuration files and dashboards should be backed up regularly to guarantee data safety and quick recoverability.
• The monitoring setup should be periodically reviewed and updated to stay aligned with the Kubernetes environment's changes and advancements.
