NME Default Azure Resource Tags

Nerdio Product Support

August 18, 2026 20:38

Nerdio Manager for Enterprise (NME) automatically applies a set of system tags to the Azure resources it manages. These tags let NME identify, classify, and track the resources it creates and operates on, including session hosts, desktop images, storage accounts, and monitoring resources.

This article lists the tags NME writes, explains what each one means, and describes the rules that govern them.

Note

Do not manually create, edit, or delete tags that use a reserved prefix. NME relies on these tags for correct operation, and manual changes can cause resources to be misidentified or mismanaged.

Key Concepts

All NME system tags share a common prefix followed by an underscore and a descriptive name, for example, NMW_OBJECT_TYPE.
The default prefix is NMW. The prefix is configurable per deployment; if a custom Azure tag prefix is set, NME writes tags with that prefix instead, for example, CONTOSO_OBJECT_TYPE.
Both the default NMW_ prefix and any configured custom prefix are treated as reserved (system) prefixes.
Tag names that begin with a reserved prefix are managed exclusively by NME. When adding custom tags, any name that starts with a reserved prefix is rejected.

Tag Reference

The tables below use the default NMW_ prefix. If your deployment uses a custom prefix, substitute it accordingly.

Frequently Asked Questions

	Can I add my own tags to NME-managed resources?
	Yes, NME supports custom tagging for resources as long as the tag name does not begin with a reserved prefix (`NMW_` or your deployment's custom prefix). See this KB for details.
	What happens if I delete an NME system tag?
	NME may no longer correctly identify or manage the resource. Do not remove system tags manually.
	Can I change the prefix?
	The prefix is set at the deployment level. Changing it affects the tags written to newly managed resources; the default `NMW_` prefix always remains reserved. Customers can change the prefix by editing the NME app service environment variable.
