Which network ports does Dynatrace Server use?

This topic applies to Dynatrace Managed installations only.

Both standalone Dynatrace Servers and Dynatrace Managed clusters require several network ports to operate, serve pages, and accept monitoring data.

Be sure to configure your network and firewall so that these ports are accessible. Note that ports should be opened for bi-directional communication.

Ports 443 and 8443 must remain open to allow incoming traffic from your data center.

Port Used by Notes
443 Dynatrace Managed user interface Routed to local port 8020 using iptables' prerouting rule. This port must remain open.
8443 Monitoring data from Dynatrace Each monitored machine with Dynatrace OneAgent installed on it must access this port. This port must remain open.
8019 Upgrade UI This port can be closed to traffic coming from outside the Dynatrace cluster. If you're running a Dynatrace Managed cluster, only your cluster nodes need access to this port.
8020, 8021 Dynatrace Managed user interface Required only internally on the Dynatrace Server machine.
5701-5711 Dynatrace cluster analytics engine These ports can be closed to traffic coming from outside the Dynatrace cluster. If you're running a Dynatrace Managed cluster, only your cluster nodes need access to these ports.
9042, 9160, 7000, 7001, 7199 Cassandra-based Hypercube storage These ports can be closed to traffic coming from outside the Dynatrace cluster. If you're running a Dynatrace Managed cluster, only your cluster nodes need access to these ports.
9200, 9300 Elasticsearch-based search engine These ports can be closed to traffic coming from outside the Dynatrace cluster. If you're running a Dynatrace Managed cluster, only your cluster nodes need access to these ports.

Outbound communication to Dynatrace Mission Control

Dynatrace clusters must be able to communicate to Mission Control (IP addresses 52.5.224.56 and 52.200.165.10, 52.221.165.63, and 13.228.109.33) via HTTPS (port 443) for license validation, health monitoring, and automatic updates. This communication can be routed via a proxy, but the proxy must allow web sockets and, if the proxy is clustered, it must provide sticky sessions for web socket communication.

To enable Dynatrace deployment health monitoring, your Dynatrace Managed Server must also have access to *.live.dynatrace.com (IP addresses 34.203.81.189, 34.205.222.178, 54.164.42.22, 52.1.155.152, and 54.164.49.176) via HTTPS (port 443).
