Infrastructure Observability

API version support for ActiveGate Kubernetes monitoring

ActiveGate Kubernetes monitoring now uses the preferred API version when querying the DynaKube endpoint instead of a fixed version.

Infrastructure Observability | Kubernetes

Added attributes for Kubernetes Enhanced Object Visibility

We have added the k8s.workload.name and k8s.workload.kind fields for top-level workloads on Smartscape nodes. This only affects Kubernetes Enhanced Object Visibility.

Infrastructure Observability | Kubernetes

ActiveGate Kubernetes monitoring: Backing off failing OpenMetrics endpoints

ActiveGate Kubernetes monitoring will now start backing off on OpenMetrics endpoints (Prometheus exporters) when either of the following occurs:

  • The HTTP request returns a 4xx or 5xx status code

  • The HTTP request fails with an exception (for example, a timeout exception).

The per-endpoint backoff duration initially doubles with each failed request and finally stays at a maximum of 60 minutes (for example, 2 min, 4 min, 8 min, 16 min, 32 min, 60 min, 60 min).

This feature can be deactivated by setting the backoff_openmetrics_enabled ActiveGate property to false.

Breaking changes

Infrastructure Observability | Extensions

Added new Python runtime distribution

The Extension Execution Controller (EEC) in an ActiveGate deployment now includes an additional Python 3.14 runtime. For details on Python 3.10 end of support, see Python 3.10 end of support.

Infrastructure Observability | Extensions
