Dynatrace provides different types of ActiveGate. ActiveGates are the only endpoints used by OneAgents to send data to Dynatrace Server.
An Environment ActiveGate is downloaded by you from your Dynatrace environment and installed within your infrastructure. An Environment ActiveGate is bound to your environment and is thus only capable of handling traffic from OneAgents that belong to the same environment as the ActiveGate.
An Environment ActiveGate can only handle traffic from OneAgents, not from other ActiveGates. An Environment ActiveGate can communicate to Dynatrace Server either directly or via a Cluster ActiveGate.
Cluster ActiveGate (Dynatrace Managed installations only)
A Cluster ActiveGate is downloaded by you from your Dynatrace Managed cluster and installed within your infrastructure. A Cluster ActiveGate is capable of handling all traffic that belongs to a Dynatrace Managed cluster (i.e., Cluster ActiveGate handles traffic from all Dynatrace environments within a cluster).
Cluster ActiveGates are typically used to set up a OneAgent connection point in some distant location (for example, a separate data center) or as a dedicated entry point into an otherwise secure location (for example, to allow receipt of messages from mobile apps or Dynatrace synthetic monitoring data).
