Will New Relic add a test‑mode flag to its agents for isolating test data?

Answer to the Question

No, New Relic does not currently provide a native test‑mode flag in its agents that would automatically separate test telemetry from production data within a single account. The platform’s architecture relies on the License Key as the primary routing identifier, and all telemetry sent with a given key is delivered to the same account.

Likely Implementation Logic

Because data isolation is enforced server‑side based on the ingest key, a simple client‑side flag cannot create a separate storage bucket. If a future version were to introduce a test‑mode flag, it would most likely act as a metadata tag rather than a routing instruction, and it would not replace the need for distinct license keys when full isolation is required.

Practical Work‑Arounds

1. Separate Accounts or License Keys: Create a dedicated New Relic account or generate a second license key for test environments. This guarantees that test data never mixes with production data and keeps billing and quota limits distinct.
2. Custom Attributes for Logical Filtering:
   • Add a custom attribute (e.g., environment = 'test') to all events in the test environment.
   • Filter dashboards or NRQL queries to exclude or include the attribute, e.g., SELECT count(*) FROM Transaction WHERE environment != 'test'.
   • Note that this method does not prevent the data from counting toward ingestion limits or billing.

Verification Steps

1. Deploy an agent with a custom attribute and confirm that the data appears in the account’s ingestion stream.
2. Run an NRQL query with a WHERE clause to ensure the attribute can be used to filter results.

Diagnostic Question

Do you require isolation for billing/quota purposes, or is the goal mainly to keep dashboards clean?
