The StackState v5.0 release delivers brand-new features and enhancements that help your team troubleshoot faster. Here are some highlights:
- New 4T® Monitors – adds a new, first-in-the-industry dimension to observability monitoring – the ability to now monitor topology and to set validation rules that span topology and multiple other parameters
- Improved Topology Visualizer and Right Panel – substantially enhances user experience and increases productivity with a more modern, focused, easy-to-learn UI and more in-depth troubleshooting capabilities.
- New StackState CLI – lets you instantly configure StackState, run queries, create monitors and more, directly from your command line, while sending output directly to other systems for GitOps integration.
- Accuracy Feedback for Anomalies – gives users the ability to provide feedback about the usefulness of the anomalies reported by StackState, so we can continuously improve the accuracy of our algorithms.
Details of the included features, improvements, bug fixes and updated StackPacks can be found below.
Features
- Introduced a new monitoring feature - 4T Monitors. STAC-14693
- Part of the API of StackState 5.0.0 has been released with an OpenAPI specification to allow for easier consumption by API clients of StackState. The OpenAPI specification can be browsed at https://dl.stackstate.com/stackstate-openapi/v5.0/openapi-v5.0.0.html STAC-16693
- The topology visualizer has been revamped. It now features much cleaner user experience and multiple helpful navigation improvements including a legend that describes the components and relations displayed. STAC-16191

refresh_tokenis now cached to prevent re-authenticating the user if the OIDC server does not return a newrefresh_tokenwhen the old one hasn't expired yet. STAC-16158 - Updated the telemetry script API to stream results. More information can be found in the StackState documentation. STAC-16801

- Security fixes for CVE-2022-24407. STAC-15939
The StackState v4.6 release brings powerful new capabilities:
- Important improvements in topology visualization to accelerate troubleshooting.
- Support for OpenTelemetry traces, specifically for serverless AWS Lambda applications built with Node.js. This new low-latency data requires no integration, and will immediately enrich your topology with additional relationships and telemetry.
- Expanded Autonomous Anomaly Detection capabilities to automatically analyze the golden signals of throughput, latency and error rate. Automatic health checks can then run on this data and alert you as soon as anomalies are found. This will help you to get to the root cause of incidents more quickly and proactively prevent problems before they occur.
Details of the included improvements and bug fixes can be found below.
