Performance Limits and Tuning

Mon, 01 Jan 0001 00:00:00 +0000

Kanvas is designed to handle a wide range of infrastructure and application configurations. However, there are some performance limits that you should be aware of when working with Kanvas. This guide will help you understand these limits and provide tips for tuning your environment for optimal performance.

Performance Limits 🔗

Maximum Number of Components 🔗

Kanvas has a maximum limit of 1,000 components per design. If you exceed this limit, you may experience performance issues such as slow loading times and laggy interactions. To avoid hitting this limit, consider breaking your design into smaller, more manageable designs.

Design Render Quality

Mon, 01 Jan 0001 00:00:00 +0000

By default, Kanvas optimizes the rendering of your designs to ensure good performance and responsiveness. This means that some computationally intensive visual elements, such as advanced relationships like TagSets (groups of components visually demarcated), might not be displayed initially to reduce system load.

To learn more about defining relationships between components, including the detailed use and creation of TagSets, please see the Creating Relationships | Layer5 Documentation.

Enable Full Render Mode 🔗

To activate this full render mode, you will need to add the render=full parameter to your Kanvas design URL. This mode ensures all elements, including TagSets, are displayed, which might otherwise be hidden for performance optimization.

Instance Details

Mon, 01 Jan 0001 00:00:00 +0000

In Kanvas, the Instance Details tab provides a detailed view of Kubernetes resources such as Nodes, Pods, Deployments, and more. This tab is essential for understanding the configuration and status of individual resources within your Kubernetes cluster. The Instance Details tab is accessible when you select a specific Kubernetes resource from the Resources tab. It allows you to view and manage the details of that resource, including its configuration, status, and associated events.

Navigating Operator

Mon, 01 Jan 0001 00:00:00 +0000

Discover and examine your Kubernetes clusters and cloud native infrastructure using Operator mode.

Using Filters 🔗

Using filters you can select the Kubernetes resources you want to view. Apply one or more filters to narrow down the resources you want to view.

Search and Select Specific Resources 🔗

Using the search bar, you can search for specific resources and select them. The selected resources are highlighted in the Operator canvas. Details of the selected resources are displayed in the right panel.

Views in Operator

Mon, 01 Jan 0001 00:00:00 +0000

The Views tab is located on the right side of the screen just beside the Details tab in Kanvas Operator. It allows you to see all containers the present in your Kubernetes cluster. Think of views for Operator mode as you would design for the Designer mode.

Managing Views 🔗

Here’s what you can do with views in Operator:

Interactive Terminal

Mon, 01 Jan 0001 00:00:00 +0000

When operating cloud native infrastructure, deep diagnostics often require direct access to the container shell. The Interactive Terminal in Kanvas enables you to execute commands and inspect the filesystem of your running containers directly from the visual topology. By integrating terminal sessions into the Kanvas interface, you can troubleshoot issues, verify configurations, and test network connectivity without switching context to external CLI tools like kubectl.

Overview 🔗

The Kanvas Interactive Terminal allows operators to establish a secure, low-latency shell session with one or more pods simultaneously. This feature is essential for “last mile” debugging where metrics and logs alone are insufficient. The interactive terminal behaves in a fashion similar to the behavior of the kubectl exec command, but web-based.

Log Streaming

Mon, 01 Jan 0001 00:00:00 +0000

Efficient troubleshooting requires immediate visibility into your application’s behavior. The Log Streamer in Kanvas allows you to live-tail logs from your Kubernetes pods and containers directly within the visual topology. Unlike static log files, this feature provides a real-time, multiplexed view of your infrastructure’s activities, enabling you to debug interactions between services without leaving the Kanvas interface.

Overview 🔗

Kanvas Log Streaming is part of the Operator mode (Visualizer). It establishes a persistent, low-latency connection to your cluster resources, allowing you to stream stdout and stderr logs from one or multiple pods simultaneously.
