Network zones - Basic information
Network zones are Dynatrace entities that represent your network structure. They help you to route the traffic efficiently, avoiding unnecessary traffic across data centers and network regions.
Activate network zones
To activate network zones
- In the Dynatrace menu, go to Settings and select Preferences > Network zones.
- Turn on Enable network zones in this environment.
Alternatively you can use the PUT global configuration API call.

Network zone naming
The name of a network zone is a string of alphanumeric characters. Additionally, you can use hyphens (
-), and underscores (
_). The length of the string is limited to 256 characters.
A dot (
.) serves as a separator in the name of the network zone (see the Naming pattern section below). You can't use it for other purposes and the network zone must not start with a dot.
Network zone names are not case-sensitive. Dynatrace stores these names in lowercase.
There is a pre-created default network zone. OneAgents use it when no network zone is specified or the setting is reset. The name default is equal to an empty name.
To make it easier for you to use network zones, we recommend the following naming pattern:
Use your company name as the
provider part if you're using your own infrastructure.
You can add additional fields to this pattern.
Alternative network zone
For each network zone, you can configure one or more alternative zones—network zones that OneAgents should use when no ActiveGate from the primary zone is available. Make sure that ActiveGates from an alternative network zone are reachable by OneAgents of the primary network zone.
To configure alternative network zones
- In the Dynatrace menu, go to Deployment status and select Network zones.
- Select the network zone you want to configure and the select Edit in the upper-right corner of the page.
Select the required network zones.
Alternatively, you can use the PUT a network zone call of the Environment API to configure the list of alternative zones.
Fallback mode determines how the network handles traffic if no ActiveGates are available in this network zone and there are no alternative network zones.
Available fallback modes:
- Any ActiveGate (default): Traffic is routed to any available ActiveGate if the primary network zone is not accessible.
- Only DefaultZone: Traffic is directed only to the default network zone.
- None (drop traffic): Traffic is discarded if the primary network zone is unavailable.
Configure fallback mode
In the Dynatrace menu, go to Deployment status and select Network zones.
Choose the network zone for which you want to set the fallback mode.
Note that the default network zone is not configurable.
In the Fallback mode section, select a fallback mode from the list.
Select Save changes.
