As I receive many questions about why Dynatrace Managed doesn't support Red Hat Enterprise Linux 8.5 I've decided to write a community post about this.
We do not plan to add support for RHEL 8.5, 8.7 and 8.9 versions as Red Hat doesn't include for those Extended Update Support - in practice they are supported only for 6 months. We recommend to stay on 8.4, 8.6, or 8.8 respectively for a longer time till a new patch is released.
Hope you find it well. Feel free to leave feedback here.
