Prometheus Our Service Leads use Prometheus as a powerful monitoring and alerting system for Kubernetes. It collects real-time metrics, stores them in a time-series database, and enables querying with PromQL. With built-in alerting and visualisation support, Prometheus helps monitor application performance, detect anomalies, and ensure system reliability and scalability.

Helm Our Service Leads use Helm, which is a package manager for Kubernetes. It uses 'charts' as its package format, which is based on YAML.

Alertmanager Alertmanager is a component of Prometheus that handles alerts by deduplicating, grouping, and routing them to different notification channels such as email, Slack, PagerDuty, and OpsGenie. It supports silencing and inhibition to prevent alert fatigue and ensure only critical issues are escalated. It is commonly used in cloud-native and Kubernetes-based monitoring setups.
