Overview

Available in v1.28.4+

The Cluster Network Flow page is a visual map of how your workloads communicate with each other and with external services. It shows the top workloads in the cluster ranked by traffic volume, connected by lines whose thickness reflects how much data flows between them.

Workloads are grouped inside a “Cluster” boundary, while AWS services like RDS, SQS, and S3 appear outside it in a “VPC” boundary, making it easy to see which workloads are talking to which cloud services. Each connection also breaks down traffic into in-zone vs. cross-zone, helping identify costly cross-availability-zone data transfer.

Key Features

Filtering and Time Range

The interface provides flexible filtering capabilities to focus on specific areas of interest:

• Namespace filtering: View traffic for specific namespaces
• Label filtering: Filter workloads by label selectors
• Workload filtering: Focus on specific workloads
• Time range adjustment: Analyze traffic patterns across different time periods
• Workload count control: Adjust how many workloads are displayed in the visualization

Filters are affecting what are the top workloads that will be presented in the map.

Interactive Navigation

Clicking on any workload zooms into a detailed view of that workload’s connections. You can navigate back and forth between views to explore different parts of your network topology.

Traffic Visualization

Hovering over a node or connection highlights the relevant traffic path and displays a tooltip with the exact traffic breakdown, including:

• Total traffic volume
• In-zone traffic
• Cross-zone traffic
• Traffic direction (ingress/egress)
