September 2024
In this release, we've introduced several new features and enhancements to make troubleshooting faster and more efficient, along with bug fixes to improve the overall stability of the platform. From interactive service maps to a more intuitive issue resolution process, our goal is to provide you with the tools needed to resolve issues more accurately. Key updates include improved stack trace support, infrastructure monitoring at the cluster level, and a integrations with Slack. We’ve also significantly improved the user interface and experience across various pages, ensuring a cleaner, more informative, and easier-to-use interface.
New Features
Interactive service maps for issue resolution – A real-time visual representation of service interactions, showing request flows, error rates, and performance metrics across your system so you can quickly pinpoint issues and identify affected services for faster troubleshooting.
Added native stack trace support for Java, JavaScript, and Golang. This feature provides language-specific error tracing, allowing developers to quickly identify and resolve issues in their codebases with detailed, language-tailored stack information.
Endpoint Grouping Enhancement: Introduced a feature to consolidate and group similar endpoint URLs by abstracting away dynamic parameters. This reduces noise in the system, allowing developers to focus on identifying problematic endpoints without being overwhelmed by unnecessary detail.
Normal State Metric Baseline: Introduced a new feature that calculates a "normal state" for each metric based on a service or endpoint's historical behavior. This helps developers quickly determine whether observed metrics, like error rates, are within normal ranges or cause for concern. Instead of guessing if a 15-20% error rate is problematic, developers will now have clear context based on past performance to assess and act on potential issues faster.
K8s Infrastructure Metrics: Added Kubernetes infrastructure metrics at the cluster, node, and pod levels to provide better context during issue resolution. This feature helps developers quickly differentiate between infrastructure-related and application-specific issues, speeding up the troubleshooting process.
Slack Integration for New Issues: Introduced an initial Slack integration that sends notifications for new issues directly to a dedicated "Kerno" channel. This allows teams to stay informed about critical problems in real time. Future updates will expand notification options for more event types.
Log Capture for Issues: Introduced log capture functionality for issues, allowing detailed logs to be automatically collected and attached to issue reports. This gives developers immediate access to relevant logs during troubleshooting, speeding up the identification and resolution of problems.
Cluster View: Introduced a new cluster view feature, allowing users to assess the overall health of their Kubernetes cluster at a glance. This feature provides a comprehensive overview of every component running within the cluster, helping developers quickly identify any issues affecting the system.
Improvements
Consistent 'Empty Data' Messages—Standardized the 'Empty Data' messages across the app for a more uniform and cohesive user experience.
Infrastructure Color Coding—Updated bullet points in the infrastructure details to reflect status-based colors. The colors now indicate the health or status of components, providing clearer insight into system conditions.
Interactive Graphs—Enhanced graphs to be interactive, allowing for better filtering of errors and events. This provides users with more control and deeper insights while troubleshooting.
Issue Resolution Page Rework—Reworked the Issue Resolution page with a redesigned UX/UI for better clarity and usability. Unnecessary data has been removed, new informative visualizations have been added, and the layout has been cleaned up to improve issue troubleshooting.
Persistent Table Sorting—Table sorting is now persisted throughout a session. When users navigate away and return to the components table, their previous sorting preferences are retained for a smoother experience.
Bug Fixes
K8s metrics—Fixed an issue where null usage metric values were not being sent. Now, null values are correctly passed, as they are filtered out before sending node and pod usage metrics, ensuring more accurate and reliable metric reporting.
Missing Resources in Infrastructure Details—Fixed an issue where resources were not listed in the infrastructure details section if they weren't created or updated within the selected timeframe. Now, all relevant resources are displayed regardless of their creation/update date, ensuring comprehensive visibility.
Issue Details Window Resize Glitch—Fixed a glitch where the chart on the Issue Details page would behave erratically during window resizing. The chart now adjusts smoothly and without glitches when the window is resized.
UI Improvements and Minor Fixes—Addressed various small bugs, including UI inconsistencies, incorrect labels, and graph sizing issues. These fixes enhance the overall user experience by improving visual alignment and accuracy across the interface.
