New features and enhancements

Chromium support for private Synthetic locations

Digital Experience | Synthetic Monitoring

Chromium 117 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 117 is bundled with the Windows ActiveGate installer.

Note that Chromium development for Ubuntu 18.04 stopped at version 112.

For more information on supported and provided Chromium versions, see Requirements for private Synthetic locations and Create a private Synthetic location.

Chromium WebP library vulnerability

Digital Experience | Synthetic Monitoring

Chromium 116.0.5845.187+ fixes a security issue in the Chromium WebP library. This version is available for Windows and Ubuntu 20.04 and 22.04 on ActiveGate 1.273. A Chromium 117 package that fixes this issue is available for supported Linux distributions.

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.
