 | `NEW_RELIC_LICENSE_KEY_SECRET` | | Secret Name or ARN | Specify the name or ARN of the secret from **AWS Secrets Manager** that contains your New Relic license key.<br><br>**Notes:**<br>- This is only used if `NEW_RELIC_LICENSE_KEY` is not set.<br>- The secret must be in the same AWS region as your Lambda function.<br>- Your Lambda function's execution role needs the `secretsmanager:GetSecretValue` permission for this secret. |
 | `NEW_RELIC_LICENSE_KEY_SSM_PARAMETER_NAME` | | Parameter Name or ARN | Specify the name or ARN of the parameter from the **AWS Systems Manager Parameter Store** that contains your New Relic license key.<br><br>**Notes:**<br> - This is only used if `NEW_RELIC_LICENSE_KEY` is not set.<br> - The SSM parameter must be in the same AWS region as your Lambda function.<br> - Your Lambda function's execution role needs the `ssm:GetParameter` permission for this parameter. |
 | `NEW_RELIC_CLOUD_AWS_ACCOUNT_ID` | | AWS Account ID | Provide the AWS Account ID where your monitored resources (e.g., databases, Lambda functions) are located. This allows New Relic to correctly map and display relationships between these monitored entities. |
+| `NEW_RELIC_APP_NAME` | Lambda function name | String | Sets the APM entity name for this Lambda function in New Relic. When set, the function reports under a named entity instead of using the Lambda function name. Also used to group multiple Lambda functions (across regions or deployments) into a single APM entity. Each language runtime creates its own entity — same name across different runtimes results in separate entities. |
+| `NEW_RELIC_APM_DISABLE_TELEMETRY` | _(empty)_ | Comma-separated list of: `metric_data`, `custom_event_data`, `log_event_data`, `analytic_event_data`, `error_event_data`, `error_data`, `span_event_data`, `sql_trace_data`, `transaction_sample_data`, `platform_metrics` | APM mode only. Telemetry types listed here are **not sent** (and not buffered/retried). Unknown tokens are ignored with a warning. Example: `NEW_RELIC_APM_DISABLE_TELEMETRY=platform_metrics,sql_trace_data` drops the per-invocation `apm.lambda.*` platform metrics and SQL traces. `platform_metrics` also skips REPORT→metric conversion entirely. Does not affect the APM handshake or error synthesis memory capture. |
 | `NEW_RELIC_APM_BLOCKING_HANDSHAKE` | `false` | `true`, `false`, `1`, `0` | When `true`, the extension holds `/next` after `platform.runtimeDone` until the APM PreConnect+Connect handshake finishes (or the remaining invoke deadline is exhausted). Improves the likelihood that APM is connected before the sandbox is frozen — useful for sparse-traffic functions (infrequent invocations) or very short function timeouts where the background handshake may not complete in time. When `false` (default), the handshake runs in the background and APM connects within a few invocations for high-frequency functions. |
 | `NEW_RELIC_APM_HANDSHAKE_TIMEOUT_SECS` | `5` | Number (min: 1) | Maximum seconds to wait for each individual APM PreConnect or Connect request to the New Relic collector. Increase if your function runs in a high-latency network (e.g., cross-region VPC). The total handshake (PreConnect + Connect) can take up to `2 × timeout`. |
 | `NEW_RELIC_RUNTIME_DONE_GRACE_MS` | `25` | Number (0–2000) | Grace period in milliseconds added after the `platform.runtimeDone` signal before the end-of-invocation log flush. Only active when the log batch is not already fully drained. Increasing this gives trailing telemetry (emitted by the agent just before the function returns) more time to arrive. Clamped to `[0, 2000]`. |
