Overview

Package ext contains a set of Datadog-specific constants. Most of them are used for setting span metadata.

Constants

View Source
const (
	// DEPRECATED: Use SpanTypeWeb
	// AppTypeWeb specifies the Web span type and can be used as a tag value
	// for a span's SpanType tag.
	AppTypeWeb = "web"

	// AppTypeDB specifies the DB span type and can be used as a tag value
	// for a span's SpanType tag. If possible, use one of the SpanType*
	// constants for a more accurate indication.
	AppTypeDB = "db"

	// AppTypeCache specifies the Cache span type and can be used as a tag value
	// for a span's SpanType tag. If possible, consider using SpanTypeRedis or
	// SpanTypeMemcached.
	AppTypeCache = "cache"

	// AppTypeRPC specifies the RPC span type and can be used as a tag value
	// for a span's SpanType tag.
	AppTypeRPC = "rpc"
)

App types determine how to categorize a trace in the Datadog application. For more fine-grained behaviour, use the SpanType* constants.

const (
	// SpanTypeWeb marks a span as an HTTP server request.
	SpanTypeWeb = "web"

	// SpanTypeHTTP marks a span as an HTTP client request.
	SpanTypeHTTP = "http"

	// SpanTypeSQL marks a span as an SQL operation. These spans may
	// have an "sql.command" tag.
	SpanTypeSQL = "sql"

	// SpanTypeCassandra marks a span as a Cassandra operation. These
	// spans may have an "sql.command" tag.
	SpanTypeCassandra = "cassandra"

	// SpanTypeRedis marks a span as a Redis operation. These spans may
	// also have a "redis.raw_command" tag.
	SpanTypeRedis = "redis"

	// SpanTypeMemcached marks a span as a memcached operation.
	SpanTypeMemcached = "memcached"

	// SpanTypeMongoDB marks a span as a MongoDB operation.
	SpanTypeMongoDB = "mongodb"

	// SpanTypeElasticSearch marks a span as an ElasticSearch operation.
	// These spans may also have an "elasticsearch.body" tag.
	SpanTypeElasticSearch = "elasticsearch"

	// SpanTypeLevelDB marks a span as a leveldb operation
	SpanTypeLevelDB = "leveldb"

	// SpanTypeDNS marks a span as a DNS operation.
	SpanTypeDNS = "dns"

	// SpanTypeMessageConsumer marks a span as a queue operation
	SpanTypeMessageConsumer = "queue"

	// SpanTypeMessageProducer marks a span as a queue operation.
	SpanTypeMessageProducer = "queue"

	// SpanTypeConsul marks a span as a Consul operation.
	SpanTypeConsul = "consul"

	// SpanTypeGraphql marks a span as a graphql operation.
	SpanTypeGraphQL = "graphql"
)

Span types have similar behaviour to "app types" and help categorize traces in the Datadog application. They can also help fine grain agent level behaviours such as obfuscation and quantization, when these are enabled in the agent's configuration.
