Go agent attributes

Attributes are key-value pairs containing information for transaction events, error events, and traced errors. You can adjust the destinations of default attributes and create custom attributes for the attributes collected by New Relic's Go language agent, including:

Error traces
Transaction events
Page views

For an extra level of monitoring detail, create custom attributes.

The Go agent receives the following default attributes from your app. You can adjust these default settings and turn attributes on or off for certain destinations.

The name of the server host under which the current script is executing, called with newrelic.AttributeHostDisplayName.

Default settings:

Transaction traces: Enabled
Error collector (traced errors): Enabled
Transaction events: Disabled
Example of excluding this attribute:
```
config.Attributes.Exclude = append(config.Attributes.Exclude, newrelic.AttributeHostDisplayName)
```

The response status code for a web request, called with newrelic.AttributeResponseCodeDeprecated

Default settings:

Transaction traces: Enabled
Error collector (traced errors): Enabled

Transaction events: Enabled

Example of excluding this attribute:

config.Attributes.Exclude = append(config.Attributes.Exclude, newrelic.AttributeResponseCodeDeprecated)

重要

As of Go agent v3.0.0, this attribute has been marked deprecated and been renamed to http.statusCode. The v3.x agent will continue to produce this attribute, but it will be removed in v4.0.0.

The type as read from the HTTP request's Accept header, called with newrelic.AttributeRequestAccept

Default settings:

Transaction traces: Enabled
Error collector (traced errors): Enabled

Transaction events: Enabled

Example of excluding this attribute:

config.Attributes.Exclude = append(config.Attributes.Exclude, newrelic.AttributeRequestAccept)

The incoming request size in bytes as read from the Content-Length request header, called with newrelic.AttributeRequestContentLength.

Default settings:

Transaction traces: Enabled
Error collector (traced errors): Enabled

Transaction events: Enabled

Example of excluding this attribute:

config.Attributes.Exclude = append(config.Attributes.Exclude, newrelic.AttributeRequestContentLength)

The incoming request content type as read from the Content-Type request header, called with newrelic.AttributeRequestContentType.

Default settings:

Transaction traces: Enabled
Error collector (traced errors): Enabled

Transaction events: Enabled

Example of excluding this attribute:

config.Attributes.Exclude = append(config.Attributes.Exclude, newrelic.AttributeRequestContentType)

The name from the HTTP host request header, called with newrelic.AttributeRequestHost.

Default settings:

Transaction traces: Enabled
Error collector (traced errors): Enabled

Transaction events: Enabled

Example of excluding this attribute:

config.Attributes.Exclude = append(config.Attributes.Exclude, newrelic.AttributeRequestHost)

The incoming request referer as read from the Referer request header, called with newrelic.AttributeRequestReferer.

Default settings:

Transaction traces: Enabled
Error collector (traced errors): Enabled

Transaction events: Disabled

Example of excluding this attribute:

config.Attributes.Exclude = append(config.Attributes.Exclude, newrelic.AttributeRequestReferer)

The contents of the User-Agent HTTP header, called with newrelic.AttributeRequestUserAgentDeprecated

Default settings:

Transaction traces: Enabled
Error collector (traced errors): Enabled
Transaction events: Disabled
Example of excluding this attribute:
```
config.Attributes.Exclude = append(config.Attributes.Exclude, newrelic.AttributeRequestUserAgentDeprecated)
```
重要
As of Go agent v3.0.0, this attribute has been marked deprecated and been renamed to request.headers.userAgent. The v3.x agent will continue to produce this attribute, but it will be removed in v4.0.0.

The contents of the User-Agent HTTP header, called with newrelic.AttributeRequestUserAgent

Default settings:

Transaction traces: Enabled
Error collector (traced errors): Enabled
Transaction events: Disabled
Example of excluding this attribute:
```
config.Attributes.Exclude = append(config.Attributes.Exclude, newrelic.AttributeRequestUserAgent)
```
重要
This attribute was added in v3.0.0 of the agent and the original request.headers.User-Agent will eventually be removed. Therefore the v3.x agents will produce two attributes representing the the contents of the User-Agent HTTP header. To completely exclude the attribute when using the v3.x agent, you must include both the old and new attributes. For example:
config.Attributes.Exclude = append(config.Attributes.Exclude, newrelic.AttributeRequestUserAgent, newrelic.AttributeRequestUserAgentDeprecated, )

The HTTP method of the incoming request, called with newrelic.AttributeRequestMethod

Default settings:

Transaction traces: Enabled
Error collector (traced errors): Enabled

Transaction events: Enabled

Example of excluding this attribute:

config.Attributes.Exclude = append(config.Attributes.Exclude, newrelic.AttributeRequestMethod)

The outgoing response size in bytes as read from the Content-Length response header, called with newrelic.AttributeResponseContentLength.

Default settings:

Transaction traces: Enabled
Error collector (traced errors): Enabled

Transaction events: Enabled

Example of excluding this attribute:

config.Attributes.Exclude = append(config.Attributes.Exclude, newrelic.AttributeResponseContentLength)

The outgoing response content-type as read from the Content-Type response header, called with newrelic.AttributeResponseContentType.

Default settings:

Transaction traces: Enabled
Error collector (traced errors): Enabled

Transaction events: Enabled

Example of excluding this attribute:

config.Attributes.Exclude = append(config.Attributes.Exclude, newrelic.AttributeResponseContentType)

The response status code for a web request, called with newrelic.AttributeResponseCode

Default settings:

Transaction traces: Enabled
Error collector (traced errors): Enabled
Transaction events: Enabled
Example of excluding this attribute:
```
config.Attributes.Exclude = append(config.Attributes.Exclude, newrelic.AttributeResponseCode)
```
重要
This attribute was added in v3.0.0 of the agent and the original httpResponseCode will eventually be removed. Therefore the v3.x agents will produce two attributes representing the response status code for a web request. To completely exclude the attribute when using the v3.x agent, you must include both the old and new attributes. For example:
config.Attributes.Exclude = append(config.Attributes.Exclude, newrelic.AttributeResponseCode, newrelic.AttributeResponseCodeDeprecated, )

Span and segment attributes

If you have Go agent v2.6.0 or higher, you can configure attributes on spans and segments. The Go agent receives the following default attributes from your app. These attributes are only found on span events and transaction trace segments. You can adjust these default settings and turn attributes on or off for certain destinations.

For datastore segments, this is the collection used and represents the table or group, called with newrelic.SpanAttributeDBCollection.

Default settings:

Transaction trace segments: Enabled

Span events: Enabled

Example of excluding this attribute:

config.Attributes.Exclude = append(config.Attributes.Exclude, newrelic.SpanAttributeDBCollection)

For datastore segments this is the database name and represents the name of the database where the query is being executed, called with newrelic.SpanAttributeDBInstance.

Default settings:

Transaction trace segments: Enabled

Span events: Enabled

Example of excluding this attribute:

config.Attributes.Exclude = append(config.Attributes.Exclude, newrelic.SpanAttributeDBInstance)

For datastore segments this is the parameterized query being executed and represents the query being performed, called with newrelic.SpanAttributeDBStatement.

Default settings:

Transaction trace segments: Enabled

Span events: Enabled

Example of excluding this attribute:

config.Attributes.Exclude = append(config.Attributes.Exclude, newrelic.SpanAttributeDBStatement)

For external segments this is the http method of the outgoing request, called with newrelic.SpanAttributeHTTPMethod.

Default settings:

Transaction trace segments: Enabled

Span events: Enabled

Example of excluding this attribute:

config.Attributes.Exclude = append(config.Attributes.Exclude, newrelic.SpanAttributeHTTPMethod)

For external segments this is the url of the outgoing request, called with newrelic.SpanAttributeHTTPURL.

Default settings:

Transaction trace segments: Enabled

Span events: Enabled

Example of excluding this attribute:

config.Attributes.Exclude = append(config.Attributes.Exclude, newrelic.SpanAttributeHTTPURL)

For datastore segments this is the hostname plus port of the database being queried, called with newrelic.SpanAttributePeerAddress.

Default settings:

Transaction trace segments: Enabled

Span events: Enabled

Example of excluding this attribute:

config.Attributes.Exclude = append(config.Attributes.Exclude, newrelic.SpanAttributePeerAddress)

For datastore segments this is the hostname of the database being queried, called with newrelic.SpanAttributePeerHostname.

Default settings:

Transaction trace segments: Enabled

Span events: Enabled

Example of excluding this attribute:

config.Attributes.Exclude = append(config.Attributes.Exclude, newrelic.SpanAttributePeerHostname)

Change attribute destination

Use these options to change attribute destinations:

To open or close an entire destination to attributes, set the .Enabled flag to true or false.

For example, to turn off APM error collection: After the config, add:

config.ErrorCollector.Attributes.Enabled = false

To turn specific attributes on or off, use the .Include or .Exclude methods.

For example, to disable AttributeResponseCode: After the config, add:

config.Attributes.Exclude = append(config.Attributes.Exclude, newrelic.AttributeResponseCode)

Create custom attributes

Add custom attributes by using this method in a transaction:

txn.AddAttribute("key", "value")

The txn variable is the one instrumented for the Go transaction. For example:

txn.AddAttribute("product", "widget")
txn.AddAttribute("price", 19.99)
txn.AddAttribute("importantCustomer", true)

Default settings for custom attribute destinations:

Error collector (traced errors): Enabled
Transaction events: Enabled
