Which network ports does ActiveGate use?

See the ports you need to open for your ActiveGates, depending on their types and your deployment scenario.


Default port Origin Destination Protocol Notes
9999 OneAgent Environment and Cluster ActiveGate HTTPS
9999 Environment ActiveGate Cluster ActiveGate HTTPS Dynatrace Managed only
8443 Environment and Cluster ActiveGate Managed Cluster node HTTPS Dynatrace Managed only
443 Environment ActiveGate Cloud/virtualization environments (AWS, VMware, Azure, GCP) HTTPS
443 Environment ActiveGate Dynatrace Server HTTPS Dynatrace SaaS only

The port 9999 that is used for communication with OneAgents and other ActiveGates can be manually re-configured in the ActiveGate custom.properties file.

If you use Browser monitors or HTTP monitors in private synthetic locations, you need to make sure the synthetic-enabled ActiveGate has access to the tested resource. If you use ActiveGate plugins, you need to make sure the ActiveGate executing the plugins has access to the monitored technology.

For Dynatrace Managed, ActiveGate must have network access to other services as well on specific ports, based on your deployment scenario.
