Seathru: Network Visibility

Modern applications are built from many microservices running in dynamic cloud or Kubernetes clusters, rather than monolithic applications. Tracking the intricate network interactions between these services is crucial but challenging with traditional monitoring tools.

Seathru addresses this by providing comprehensive network observability for microservice environments, enabling developers and operators to visualize communication flows, identify bottlenecks, and detect anomalies.

How Seathru Works

Seathru operates by deploying lightweight agents alongside your services within your cloud cluster. These agents are designed to capture network flow data directly at the source, observing all incoming and outgoing traffic for each service.

Data Capture and Analysis

Once captured, this flow data is securely transmitted to a central Seathru analyzer. The analyzer aggregates data from all agents across different regions, providing a unified view of your entire application's network activity. This centralized hub then processes the raw flow data to construct a detailed map of all service-to-service communication.

Visualizing Communication and Performance

Seathru automatically identifies and maps out every connection, including the protocols and ports used (e.g., HTTP/1.1 on :8080, gRPC on :50051). This visibility allows you to understand which services are talking to each other, how frequently, and over what paths. Beyond just mapping connections, Seathru continuously monitors traffic patterns to highlight unusual or unauthorized access attempts and deviations from expected behavior.

Identifying Bottlenecks

One of Seathru's key capabilities is identifying performance bottlenecks. By tracking network latency between services, it can pinpoint specific connections experiencing delays. For example, if a user reports slow application responses, Seathru's dashboard can quickly highlight a connection with unusually high latency, such as a database query taking hundreds of milliseconds, indicating the precise point of contention. This allows operators to swiftly investigate and resolve the root cause.
