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 > Preferences > Network zones.
Activate Enable network zones in this environment.

Alternatively you can use the PUT global configuration API call.

SaaS vs Managed

Network zones are organized per environment. You can get an overview of network zones via Environment API or on the Deployment status > Network zones page.	Network zones are organized per Managed cluster. You can get an overview of network zones in Cluster Management Console or via Cluster API.

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 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.

Naming pattern

To make it easier for you to use network zones, we recommend the following naming pattern:

plaintext
provider.region.availability-zone.datacenter.tier

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 primary network zone.

To configure alternative network zones

In the Dynatrace menu, go to Deployment status > Network zones item.
Select the network zone you want to configure and click Edit in the upper-right corner of the screen.
Select the required network zones.

Alternatively, you can use the PUT a network zone call of Environment API to configure the list of alternative zones.
