      • DB_NAME

        public static final io.opentelemetry.api.common.AttributeKey<String> DB_NAME
        If no tech-specific attribute is defined, this attribute is used to report the name of the database being accessed. For commands that switch the database, this should be set to the target database (even if the command fails).

        Notes:

        • In some SQL databases, the database name to be used is called "schema name".

      • DB_STATEMENT

        public static final io.opentelemetry.api.common.AttributeKey<String> DB_STATEMENT
        The database statement being executed.

        Notes:

        • The value may be sanitized to exclude sensitive information.

      • DB_OPERATION

        public static final io.opentelemetry.api.common.AttributeKey<String> DB_OPERATION
        The name of the operation being executed, e.g. the MongoDB command name such as findAndModify, or the SQL keyword.

        Notes:

        • When setting this to an SQL keyword, it is not recommended to attempt any client-side parsing of db.statement just to get this property, but it should be set if the operation name is provided by the library being instrumented. If the SQL statement has an ambiguous operation, or performs more than one operation, this value may be omitted.

      • DB_MSSQL_INSTANCE_NAME

        public static final io.opentelemetry.api.common.AttributeKey<String> DB_MSSQL_INSTANCE_NAME
        The Microsoft SQL Server instance name connecting to. This name is used to determine the port of a named instance.

      • DB_CASSANDRA_KEYSPACE

        public static final io.opentelemetry.api.common.AttributeKey<String> DB_CASSANDRA_KEYSPACE

        The name of the primary table that the operation is acting upon, including the schema name (if applicable).

        Notes:

        • This mirrors the db.sql.table attribute but references cassandra rather than sql. It is not recommended to attempt any client-side parsing of db.statement just to get this property, but it should be set if it is provided by the library being instrumented. If the operation is acting upon an anonymous table, or more than one table, this value MUST NOT be set.

      • DB_CASSANDRA_IDEMPOTENCE

        public static final io.opentelemetry.api.common.AttributeKey<Boolean> DB_CASSANDRA_IDEMPOTENCE
        Whether or not the query is idempotent.

        Notes:

        • It is not recommended to attempt any client-side parsing of db.statement just to get this property, but it should be set if it is provided by the library being instrumented. If the operation is acting upon an anonymous table, or more than one table, this value MUST NOT be set.

      • EXCEPTION_TYPE

        public static final io.opentelemetry.api.common.AttributeKey<String> EXCEPTION_TYPE

      • EXCEPTION_ESCAPED

        public static final io.opentelemetry.api.common.AttributeKey<Boolean> EXCEPTION_ESCAPED
        SHOULD be set to true if the exception event is recorded at a point where it is known that the exception is escaping the scope of the span.

        Notes:

        • An exception is considered to have escaped (or left) the scope of a span, if that span is ended while the exception is still logically "in flight". This may be actually "in flight" in some languages (e.g. if the exception is passed to a Context manager's __exit__ method in Python) but will usually be caught at the point of recording the exception in most languages.
        • It is usually not possible to determine at the point where an exception is thrown whether it will escape the scope of a span. However, it is trivial to know that an exception will escape, if one checks for an active exception just before ending the span, as done in the example above.
        • It follows that an exception may still escape the scope of the span even if the exception.escaped attribute was not set or set to false, since the event might have been recorded at a time where it was not clear whether the exception will escape.

        Notes:

        • http.url is usually not readily available on the server side but would have to be assembled in a cumbersome and sometimes lossy process from other information (see e.g. open-telemetry/opentelemetry-python/pull/148). It is thus preferred to supply the raw data that is available.

        public static final io.opentelemetry.api.common.AttributeKey<Long> MESSAGING_MESSAGE_PAYLOAD_SIZE_BYTES
        The (uncompressed) size of the message payload in bytes. Also use this attribute if it is unknown whether the compressed or uncompressed payload size is reported.

      • MESSAGING_MESSAGE_PAYLOAD_COMPRESSED_SIZE_BYTES

        public static final io.opentelemetry.api.common.AttributeKey<Long> MESSAGING_MESSAGE_PAYLOAD_COMPRESSED_SIZE_BYTES

        public static final io.opentelemetry.api.common.AttributeKey<String> MESSAGING_KAFKA_MESSAGE_KEY
        Message keys in Kafka are used for grouping alike messages to ensure they're processed on the same partition. They differ from messaging.message_id in that they're not unique. If the key is null, the attribute MUST NOT be set.

        Notes:

        • If the key type is not string, it's string representation has to be supplied for the attribute. If the key has no unambiguous, canonical string form, don't include its value.

      • MESSAGING_KAFKA_CONSUMER_GROUP

        public static final io.opentelemetry.api.common.AttributeKey<String> MESSAGING_KAFKA_CONSUMER_GROUP

      • MESSAGING_KAFKA_CLIENT_ID

        public static final io.opentelemetry.api.common.AttributeKey<String> MESSAGING_KAFKA_CLIENT_ID

        public static final io.opentelemetry.api.common.AttributeKey<String> RPC_SERVICE
        The full (logical) name of the service being called, including its package name, if applicable.

        Notes:

        • This is the logical name of the service from the RPC interface perspective, which can be different from the name of any implementing class. The code.namespace attribute may be used to store the latter (despite the attribute name, it may include a class name; e.g., class with method actually executing the call on the server side, RPC client stub class on the client side).

      • RPC_METHOD

        public static final io.opentelemetry.api.common.AttributeKey<String> RPC_METHOD
        The name of the (logical) method being called, must be equal to the $method part in the span name.

        Notes:

        • This is the logical name of the method from the RPC interface perspective, which can be different from the name of any implementing method/function. The code.function attribute may be used to store the latter (e.g., method actually executing the call on the server side, RPC client stub method on the client side).

      • RPC_GRPC_STATUS_CODE

        public static final io.opentelemetry.api.common.AttributeKey<Long> RPC_GRPC_STATUS_CODE
        The numeric status code of the gRPC request.

        public static final io.opentelemetry.api.common.AttributeKey<String> RPC_JSONRPC_VERSION
        Protocol version as in jsonrpc property of request/response. Since JSON-RPC 1.0 does not specify this, the value can be omitted.

      • RPC_JSONRPC_REQUEST_ID

        public static final io.opentelemetry.api.common.AttributeKey<String> RPC_JSONRPC_REQUEST_ID
        id property of request or response. Since protocol allows id to be int, string, null or missing (for notifications), value is expected to be cast to string for simplicity. Use empty string in case of null value. Omit entirely if this is a notification.

      • RPC_JSONRPC_ERROR_CODE

        public static final io.opentelemetry.api.common.AttributeKey<Long> RPC_JSONRPC_ERROR_CODE
        error.code property of response if it is an error response.

      • RPC_JSONRPC_ERROR_MESSAGE

        public static final io.opentelemetry.api.common.AttributeKey<String> RPC_JSONRPC_ERROR_MESSAGE
        error.message property of response if it is an error response.

      • EXCEPTION_EVENT_NAME

        public static final String EXCEPTION_EVENT_NAME
        The name of an event describing an exception.

        Typically an event with that name should not be manually created. Instead Span.recordException(Throwable) should be used.
