v5.0.0 (2022-06-24)

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
First release of a completely new, easier to install CLI, supporting the new features of StackState such as 4T Monitors and Service Tokens. STAC-15281
Anomalies can now be marked with a thumbs-up or thumbs-down. This feedback can be exported via the CLI and sent to StackState to help further develop test sets and algorithms for the AAD. STAC-15270
The right panel in the StackState UI has been revamped. It now supports multiple tabs and chaining of selected elements. STAC-14808

Improvements

Introduced service tokens as a means of authenticating to StackState. Service tokens are not tied to a principal, but instead to a set of roles, allowing for service authentication. More information on creating and managing these can be found in the StackState documentation. STAC-15016
Introduced optional View access logging. When enabled, a new access log for StackState views is created under logs/access/. This log allows you to track how often specific views are accessed and by which user. To enable this feature, you need to enable the feature flag featureSwitches.viewAccessLogs in the StackState Api config. STAC-16369
The OIDC refresh_token is now cached to prevent re-authenticating the user if the OIDC server does not return a new refresh_token when 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
kafkaup-operator Helm chart: Added a configurable SecurityContext so that the container no longer requires privileged mode. STAC-16664
StackState Helm chart: Added configurable resource requests and limits for all containers. STAC-16443
Improved indexing speed for messages coming in on Kafka topics. STAC-15998

Bug fixes

Added more error context when JSON deserialization fails. STAC-16733
Fixed issue that prevented relation details being displayed in the right panel when a link was clicked in the full event details. STAC-16264
Fixed DNS lookup errors by explicitly setting a short DNS lookup cache timeout on the internal JDK DNS cache. This ensures that service lookups don't fail in containerized environments. STAC-15983
Fixed issue that caused groups with big names to be displayed outside of the visualizer canvas. STAC-16844
StackState Helm Chart: The backup-scripts ConfigMap now has a label so that it can be easily retrieved in the backup/restore scripts STAC-16447
Fixed scroll position after changing group. STAC-16284
Fixed error handling of expired sessions for OIDC and Keycloak authentication methods, especially in combination with API token. STAC-15781
Fixed suggestions in telemetry inspector for values with multiple dots (domains, IPs). STAC-15764
Fixed STQL query generation for relation based problems. STAC-13333
If the OIDC configuration is wrongly configured to obtain a username, the logging will now show all fields that can be selected to obtain the username from. STAC-16027

Security

Upgraded ssl_client to 1.33.1-r7, patching the CVE-2022-28391 vulnerability. STAC-16426

Bug fixes

Fixed issue that incorrectly showed an error message when displaying a log stream. STAC-16222

v4.6.0 (2022-03-04)

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.
