New features and enhancements
Chromium support for private Synthetic locations
Digital Experience | Synthetic Monitoring
Chromium 115 is the latest supported version for Synthetic-enabled ActiveGate installed on:
- Ubuntu 18.04, 20.04, and 22.04.
- Red Hat Enterprise Linux 7 and 8.
- CentOS 7.
- Amazon Linux 2.
Chromium 115 is bundled with the Windows ActiveGate installer.
For more information on supported and provided Chromium versions, see Requirements for private Synthetic locations and Create a private Synthetic location.
Log ingest performance improvement
Infrastructure Observability | Logs
As a result of improvements to the Log Monitoring internal buffer file format in this and previous versions, we highly recommend that ActiveGate versions 1.263 or earlier not be updated directly to version 1.273+. Instead, update them first to an ActiveGate version between 1.265 and 1.271 to avoid the data loss of buffered old log events.
Kubernetes events of type Warning are root-cause relevant
Infrastructure Observability | Kubernetes
All Kubernetes events with event type Warning are considered relevant to identifying the root causes of issues. This change has two primary impacts.
- When you enable the Include important events option in cluster monitoring settings, these warning events pass through this initial filter. This means you'll see more relevant events in your monitoring feed.
- These warning events are now deemed relevant to root cause analysis, and Davis AI incorporates them into its causation analysis.
Topology assignment for kube-state-metrics
Infrastructure Observability | Kubernetes
We've improved topology assignment for kube-state-metrics—now, the assignment is based on dimension values instead of referencing the Prometheus exporter pod and its related resources. This change affects only kube-state-metrics, for example, kube_pod_*.
Additionally, Kubernetes service entities are now created based on kube-state-metrics (in the same way as for Istio metrics).
ActiveGate cloud-init support
Platform | ActiveGate
ActiveGate can now be installed as a part of the cloud-init mechanism.
