Depending on your specific requirement, ActiveGate can be used in a Dynatrace SaaS connectivity scheme or a Dynatrace Managed connectivity scheme. The Dynatrace Managed connectivity scheme can be deployed in a number of different deployment scenarios.
Dynatrace requires certain ports and paths to be opened and accessible through the monitored infrastructure, firewalls and other components. The ports are configurable and the default values are shown here.
Dynatrace SaaS connectivity scheme
All possible connections for the SaaS connectivity scheme, with preferred and alternative paths are shown below.
The solid arrows indicate the preferred paths. For example, OneAgent will connect to an Environment ActiveGate, if one is present. It will, however, connect to a the Dynatrace Saas Cluster directly, if no connection to an Environment ActiveGate is possible. The direction of arrows in the diagrams indicates which component initiates the connection.
Dynatrace Managed connectivity scheme
All possible connections for the Dynatrace Managed connectivity scheme—in all possible deployment scenarios—are shown below in one diagram.
The solid arrows indicate the preferred paths. For example, OneAgent will connect to an Environment ActiveGate, if one is present. It will, however, connect to a Cluster ActiveGate, if no connection to an Environment ActiveGate is possible, and it can even connect directly to a Dynatrace Managed Cluster. The direction of arrows in the diagrams indicates which component initiates the connection.
- Environment ActiveGate receives connections on port 9999.
- Dynatrace SaaS Cluster receives connections on port 443.
- Cluster ActiveGate receives connections on port 9999.
- Dynatrace Managed Cluster (embedded ActiveGate) receives connections on port 443.
For more information see diagrams above.
If you run Browser monitors or HTTP monitors from private Synthetic locations, you need to make sure the Synthetic-enabled ActiveGate has access to the tested resource. If you use ActiveGate extensions, you need to make sure the ActiveGate executing the extensions 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.
ActiveGates exist in the following hierarchy:
- Level 1—Environment ActiveGates
- Level 2—Cluster ActiveGates
- Level 3—Embedded ActiveGates—ActiveGates embedded within cluster nodes (not shown on graphs above).
ActiveGates can only send data to higher hierarchy levels. It is impossible to send data to the same or lower level of the hierarchy.
Connectivity can also depend on network zones if such are configured. Network zone configuration means that ActiveGates and OneAgents will prefer to communicate with ActiveGates from the same zone, before connecting to ActiveGates outside of the active zone.
