VMware invalid credentials event

Infrastructure Observability | VMware

When the VMware connecting process is blocked due to invalid credentials, a Monitoring Unavailable event is triggered. The event is active for up to 6 hour and then closed.

The event can be closed earlier if:

the affected credentials are fixed.
the affected credentials are removed completely from settings.
the problem is manually closed.

Log monitoring timestamp character search limit is configurable

Infrastructure Observability | Log Monitoring

You can now configure the timestamp character search limit as a part of a timestamp configuration rule.

Kubernetes minimum ActiveGate version is now 1.263

Infrastructure Observability | Kubernetes

To access the latest Kubernetes features, you need to deploy ActiveGate version 1.263+.

Kubernetes anomaly detection sample period and observation period limits changed

Infrastructure Observability | Kubernetes

The maximum sample period and observation period for all alerts provided by Kubernetes anomaly detection have been increased from 30 minutes to 60 minutes.

Bind variable settings for DPS and Adaptive traffic management Version 3

Application Observability | Distributed traces

Bind variable capturing can be enabled by all accounts using a Dynatrace platform subscription and tenants that are using Adaptive Traffic Management V3. No additional support request is needed.
