Correlation of observability signals.

Signal correlation for Kubernetes

Overview

There are many tools that collect observability signals from a Kubernetes clusters. Each tool may use different labelling conventions, data stores, and query languages for the data it collects.

Korrel8r calls each distinct set of tools and conventions a domain, for example.

• Container logs stored in Loki.
• Metrics and alerts stored in Prometheus.
• Kubernetes resources stored in thea API server.

Korrel8r uses rules to define relationships between data in different domains. Rules form a graph. Walking the graph can correlate data via indirect relationships that span multiple domains.
