Netsil

Netsil is an application observability and monitoring platform that analyzes network traffic to provide visibility into distributed microservices and cloud-native environments.

• Application observability and monitoring for microservices and cloud-native architectures (observability)
• Automatic discovery and mapping of application services and their dependencies (observability)
• Traffic-based analytics derived from network data without requiring code instrumentation (network monitoring)
• Dashboards and metrics for monitoring performance, latency, and health of services (APM/observability)
• Support for containerized and orchestrated environments such as Kubernetes (cloud DevOps)

More About Netsil

Netsil focuses on observability for modern distributed applications, with an emphasis on microservices, containers, and cloud-native deployments. The platform captures and analyzes network traffic to infer relationships between services, build real-time maps of application topologies, and surface metrics that operations and Site Reliability Engineering (SRE) teams use to monitor health and performance. This approach allows teams to gain visibility into complex systems without requiring developers to modify application code.

The platform operates by passively observing network protocols such as Hypertext Transfer Protocol (HTTP), HTTPS, and other service-to-service communications. From this telemetry, Netsil constructs a dependency graph of services, APIs, and backend components. This service map helps enterprise architects and infrastructure teams understand how microservices interact, which components are involved in a given transaction path, and where latency or errors occur. Because it relies on network-level data, the platform can monitor heterogeneous environments that include multiple languages, frameworks, and runtimes.

Netsil is positioned in the observability and Application Performance Management (APM) (application performance monitoring) category, with a focus on environments built on containers and orchestration platforms such as Kubernetes (cloud DevOps). In such environments, services are often short-lived and dynamically scheduled, which makes static configuration and manual dependency mapping difficult. Netsil addresses this by automatically discovering services as they appear on the network and by updating its topology maps in near real time based on observed traffic patterns.

Enterprises typically use Netsil alongside logging and metrics systems as part of a broader observability stack. While traditional APM tools often rely on code agents and manual instrumentation, Netsil emphasizes a network-centric model that can be deployed at the infrastructure layer. This can be especially useful in multi-tenant clusters or polyglot microservices estates, where standardized in-app instrumentation is complex to maintain.

From a directory perspective, Netsil aligns with categories such as observability, application performance monitoring, network-based application analytics, and cloud DevOps monitoring for container and Kubernetes environments. Its capabilities are oriented toward operations, DevOps, and SRE teams that require continuous visibility into the behavior, performance, and dependencies of distributed applications running in cloud or hybrid infrastructure.
