Rules and limits for alerts

This document contains some technical rules and limits for alerts.

Permission levels

Permissions differ depending on whether you're on our original product-based pricing model or our New Relic One pricing model:


If your organization has a parent/child account structure, child accounts do not inherit a parent account's alert policies: You must create policies separately for all child accounts.

The following rules apply both to the New Relic One user interface and to the REST API (v2).
