Configuring the Node.js SDK

Docs > APM > Application Instrumentation > Configure the Datadog SDK > Configuring the Node.js SDK

After you set up the SDK with your code and configure the Agent to collect APM data, optionally configure the SDK as desired, including setting up Unified Service Tagging.

To verify your runtime configuration and confirm settings, view the current configuration of your service in Datadog. Navigate to the APM Service Page, click Service Config, and select the SDK Configuration tab.

It is recommended that you use DD_ENV, DD_SERVICE, and DD_VERSION to set env, service, and version for your services. Review the Unified Service Tagging documentation for recommendations on configuring these environment variables.

For more examples of how to work with the library see API documentation.

Span sampling rules to keep individual spans when the rest of the trace would otherwise be dropped. A JSON array of objects. Rules are applied in configured order to determine the span’s sample rate. The sample_rate value must be between 0.0 and 1.0 (inclusive). For more information, see Ingestion Mechanisms. Example: - Set the span sample rate to 50% for the service my-service and operation name http.request, up to 50 traces per second: ‘[{“service”: “my-service”, “name”: “http.request”, “sample_rate”:0.5, “max_per_second”: 50}]’
DD_SPAN_SAMPLING_RULES_FILE: Type: string

DD_TRACE_SAMPLING_RULES: Type: array
Since: v5.83.0
Configures custom sampling rules for traces. Rules are evaluated in order, and the first matching rule determines the sampling rate. If no rules match, the default sampling rate is used. For more information about how these configurations affect trace ingestion, see Ingestion Mechanisms.
DD_TRACE_WEBSOCKET_MESSAGES_INHERIT_SAMPLING: Type: boolean
Default: true
Since: v5.83.0
By default, websocket messages preserve the same sampling as the span captured during the handshake.

Each entry can be either a bare header name (which is reported under http.request.headers.<header> for incoming requests and http.response.headers.<header> for outgoing responses) or <header>:<custom_tag_name> to control the tag key.
DD_TRACE_INFERRED_PROXY_SERVICES_ENABLED: Type: boolean
Default: false
Since: v5.83.0
Aliases:DD_TRACE_INFERRED_SPANS_ENABLED
When enabled, the tracer registers the inferred-proxy propagator, which reads x-dd-proxy* headers (currently x-dd-proxy=aws-apigateway) and starts an inferred proxy span as the parent of the server span, using header values for service, resource, and tags.
DD_TRACE_PROPAGATION_BEHAVIOR_EXTRACT: Type: string

Since: v5.88.0
Specifies how incoming distributed tracing headers should be handled at a service level. Accepted values are: continue: The SDK will continue the distributed trace if the incoming distributed tracing headers represent a valid trace context. restart: The SDK will always start a new trace. If the incoming distributed tracing headers represent a valid trace context, that trace context will be represented as a span link on service entry spans (as opposed to the parent span in the continue configuration). ignore: The SDK will always start a new trace and all incoming distributed tracing headers are ignored.
DD_TRACE_PROPAGATION_EXTRACT_FIRST: Type: boolean
Default: false
Since: v5.83.0
When set to true, stops extracting after the first successful trace context extraction.

Since: v5.88.0
Aliases:OTEL_PROPAGATORS
A comma-separated list of header formats from which to attempt to inject and extract distributed tracing propagation data. The first format found with complete and valid headers is used to define the trace to continue. The more specific DD_TRACE_PROPAGATION_STYLE_INJECT and DD_TRACE_PROPAGATION_STYLE_EXTRACT configurations take priority when present.
DD_TRACE_PROPAGATION_STYLE_EXTRACT: Type: array
Default: datadog, tracecontext, baggage
Since: v5.88.0
Aliases:DD_TRACE_PROPAGATION_STYLE
A comma-separated list of header formats from which to attempt to extract distributed tracing propagation data. The first format found with complete and valid headers is used to define the trace to continue.

Specifies which collection mode to use for automated user events.
DD_APPSEC_COLLECT_ALL_HEADERS: Type: boolean
Default: false
Since: v5.83.0
When enabled, AppSec collects all request headers for security analysis instead of only the default allowlisted subset. Because header values can contain sensitive information, this flag should be used carefully; header redaction and obfuscation settings still apply. The header-collection rules (which headers are always collected vs collected only on certain events) remain in effect unless this flag forces collection of every header
DD_APPSEC_ENABLED: Type: boolean
Since: v5.88.0
Enable Application Security Management features.
DD_APPSEC_GRAPHQL_BLOCKED_TEMPLATE_JSON: Type: string
Since: v5.83.0
Path to a local JSON response template that replaces the default backend template when the tracer performs a block action for a GraphQL request. If unset or the file cannot be read the tracer falls back to the built-in default blocking template
DD_APPSEC_HEADER_COLLECTION_REDACTION_ENABLED: Type: boolean
Default: true
Since: v5.83.0
When enabled the tracer applies the AppSec header/value redaction policies to any header values it collects.

DD_APPSEC_HTTP_BLOCKED_TEMPLATE_HTML: Type: string
Since: v5.88.0
Path to a local HTML template file that will be returned when a request is blocked and the response should be HTML.

DD_APPSEC_HTTP_BLOCKED_TEMPLATE_JSON: Type: string
Since: v5.88.0
Path to a local JSON template file that will be returned when a request is blocked and the response should be JSON. If unset or invalid, the tracer uses the default blocking HTML template defined by the product RFC. The tracer decides HTML or JSON according to Accept header or the block action’s parameters.
DD_APPSEC_MAX_COLLECTED_HEADERS: Type: int
Default: 50
Since: v5.83.0
Caps the number of headers the tracer will store/forward for AppSec purposes to avoid extremely wide span/tag vectors and large payloads. Headers beyond the configured cap are handled according to tracer policy (skipped or only name-collected). This limit protects performance and privacy; use the header collection docs for guidance on safe values.
DD_APPSEC_MAX_STACK_TRACE_DEPTH: Type: int
Default: 32
Since: v5.83.0
Aliases:DD_APPSEC_MAX_STACKTRACE_DEPTH
Maximum number of stack frames retained for any stack trace attached to an AppSec event. When the limit is reached, deeper frames are truncated and the top-of-stack frames are preserved. Lower the value to reduce event payload size.

Default: 2
Since: v5.83.0
Aliases:DD_APPSEC_MAX_STACKTRACES
Limits how many separate stacktraces are captured and attached to an AppSec/IAST event to keep payload sizes reasonable. Evidence stacktraces are useful for triage, but unbounded capture can leak sensitive data and consume excessive bandwidth; this limit balances evidence value and safety. Set to 0 to collect all.
DD_APPSEC_OBFUSCATION_PARAMETER_KEY_REGEXP: Type: string
Default: (?i)pass|pw(?:or)?d|secret|(?:api|private|public|access)[_-]?key|token|consumer[_-]?(?:id|key|secret)|sign(?:ed|ature)|bearer|authorization|jsessionid|phpsessid|asp\.net[_-]sessionid|sid|jwt
Since: v5.88.0
Regular expression used by the AppSec obfuscator to identify parameter keys whose entire value must be redacted. When a key path matches, the parameter is replaced with <redacted by datadog>. The default matches common credential names (password, token, authorization, jwt, etc.). Set to an empty string to disable key-based redaction.
DD_APPSEC_OBFUSCATION_PARAMETER_VALUE_REGEXP: Type: string
Default: (?i)(?:p(?:ass)?w(?:or)?d|pass(?:[_-]?phrase)?|secret(?:[_-]?key)?|(?:(?:api|private|public|access)[_-]?)key(?:[_-]?id)?|(?:(?:auth|access|id|refresh)[_-]?)?token|consumer[_-]?(?:id|key|secret)|sign(?:ed|ature)?|auth(?:entication|orization)?|jsessionid|phpsessid|asp\.net(?:[_-]|-)sessionid|sid|jwt)(?:\s*=([^;&]+)|"\s*:\s*("[^"]+"|\d+))|bearer\s+([a-z0-9\._\-]+)|token\s*:\s*([a-z0-9]{13})|gh[opsu]_([0-9a-zA-Z]{36})|ey[I-L][\w=-]+\.(ey[I-L][\w=-]+(?:\.[\w.+\/=-]+)?)|[\-]{5}BEGIN[a-z\s]+PRIVATE\sKEY[\-]{5}([^\-]+)[\-]{5}END[a-z\s]+PRIVATE\sKEY|ssh-rsa\s*([a-z0-9\/\.+]{100,})
Since: v5.88.0
A regex string to redact sensitive data by its value in attack reports.
DD_APPSEC_RASP_COLLECT_REQUEST_BODY: Type: boolean
Default: false
Since: v5.83.0
Controls whether the RASP (runtime exploit-prevention) collectors include the request body when performing detection or making block decisions. Request bodies can contain sensitive data and large payloads, so collection obeys size limits and obfuscation rules.
DD_APPSEC_RASP_ENABLED: Type: boolean
Default: true
Since: v5.83.0
Turns on the tracer’s RASP / Exploit Prevention capabilities. When enabled the tracer runs synchronous, pre-execution checks and may generate block actions or exploit signals. RASP may have separate activation and implementation details per language; enabling it usually activates extra synchronous instrumentation and additional evidence capture for detections
