New features and enhancements

General

  • Cluster backups that use local disk storage are no longer supported and will be disabled after the upgrade to version 1.218. This may affect clusters installed before version 1.140. Since then, we have introduced a new backup strategy for extended data coverage and increased reliability. If this change affects you, please follow our guidelines to configure a new cluster backup.
  • Dynatrace Managed now handles up to 30 nodes per cluster to further support web-scale Dynatrace deployments.
  • To improve our pro-active support and collaboration with you, we've enabled remote access approval mode to all regardless of the cluster version. Check all available cluster remote access scopes.

Cluster Management Console

We've updated our policy for data privacy and exchange in Dynatrace Managed deployments. For maximum data privacy, any data exchange that is related to the sending of usage data from users' browsers to Dynatrace for the purpose of improving Dynatrace no longer involves any 3rd party companies. This data is now sent only to Dynatrace for the purposes of self-monitoring. Following this change, we've removed the corresponding toggle at Settings > Preferences. The monitoring of user behavior now fully relies on the Dynatrace deployment health monitoring setting in the Cluster Management Console.

Installation and upgrade

Dynatrace Managed now leverages Linux capabilities (if your operating system supports it) for scripts executed with root permissions. Specifically, the following scripts were adjusted and removed from dtrun configuration file:

  • iptables-save
  • iptables -L -n
  • nft -s list ruleset
  • /opt/dynatrace-managed/nginx/services/nginx.sh (enable|disable|is-enabled|reload)
  • /opt/dynatrace-managed/upgrader/upgrader.sh (start|debug|stop)( [a-zA-Z0-9]=[^ ]*)+
  • /opt/dynatrace-managed/upgrader/upgrader-ports.sh (start|stop|status)
  • /opt/dynatrace-managed/firewall/services/firewall.sh (start|stop|restart|status|check|get-nodes|set-nodes|add-node|remove-node|get-redirect-to|set-redirect-to)[0-9., ]*

To use ambient capabilities we've added to /etc/systemd/system/dynatrace-server.service and /etc/systemd/system/dynatrace-nodekeeper.service below line: AmbientCapabilities=CAP_DAC_READ_SEARCH CAP_NET_ADMIN CAP_NET_RAW
