Kubeshark

Kubeshark is a tool for visualizing network traffic in Kubernetes clusters. By using Kubeshark, users can analyze the traffic patterns between applications running in a Kubernetes cluster and identify issues or bottlenecks.

Kubeshark provides the following key features:

• Visualization of network traffic within a Kubernetes cluster
• Interactive dashboard
• Monitoring and analysis of performance
• Integration with third-party tools

By using Kubeshark, users can visually understand the flow of network traffic within a Kubernetes cluster. This allows users to understand communication patterns of applications and the network situation, which can be useful for troubleshooting and optimization.

Kubeshark is a useful tool for visualizing network and performing analysis of performance when operating Kubernetes clusters, making it convenient for developers and system administrators.

Example of using kubeshark OSS

Kubeshark OSS is an open-source tool that enables visualization and monitoring of resources within Kubernetes clusters.

Use cases for software architecture:

Kubeshark OSS is primarily used in systems that adopt microservices architecture. In microservices architecture, multiple small services collaborate to provide functionality, requiring monitoring and debugging in complex environments. Kubeshark OSS helps visualize the performance and errors of each service on a Kubernetes cluster and assists in troubleshooting.

Reasons for use:

1. Resource monitoring: Using kubeshark OSS makes it easier to monitor various resources (Pods, services, networks, etc.) within a Kubernetes cluster. Through real-time data display and graphed information, it becomes possible to identify issues and conduct detailed analysis.

2. Debugging support: In cases of challenging debugging, kubeshark OSS supports debugging by enabling request tracing and visualization of logs, allowing tracking of the root cause of problems.

3. Improving operational efficiency: Leveraging kubeshark OSS can streamline the operational management of the entire Kubernetes environment. By utilizing anomaly detection and alert features, it is possible to enhance system stability and availability.

In this way, kubeshark OSS is used in systems adopting microservices architecture for resource monitoring, debugging support, and operational efficiency improvement.
