The full invoked ARN as provided on the Context passed to the function (Lambda-Runtime-Invoked-Function-Arn header on the /runtime/invocation/next applicable).
Note: This may be different from faas.id if an alias is involved.
The source code file name that identifies the code unit as uniquely as possible (preferably an absolute file path).
The method or function name, or equivalent (usually rightmost part of the code unit's name).
The line number in code.filepath best representing the operation. It SHOULD point within the code unit named in code.function.
The "namespace" within which code.function is defined. Usually the qualified class or module name, such that code.namespace + some separator + code.function form a unique identifier for the code unit.
The consistency level of the query. Based on consistency values from CQL.
The data center of the coordinating node for a query.
The ID of the coordinating node for a query.
Whether or not the query is idempotent.
The name of the keyspace being accessed. To be used instead of the generic db.name attribute.
The fetch size used for paging, i.e. how many rows will be returned at once.
The number of times a query was speculatively executed. Not set or 0 if the query was not executed speculatively.
The name of the primary table that the operation is acting upon, including the schema name (if applicable).
Note: 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.
The connection string used to connect to the database. It is recommended to remove embedded credentials.
The HBase namespace being accessed. To be used instead of the generic db.name attribute.
The fully-qualified class name of the Java Database Connectivity (JDBC) driver used to connect.
The collection being accessed within the database stated in db.name.
The Microsoft SQL Server instance name connecting to. This name is used to determine the port of a named instance.
Note: If setting a db.mssql.instance_name, net.peer.port is no longer required (but still recommended if non-standard).
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).
Note: In some SQL databases, the database name to be used is called "schema name".
The name of the operation being executed, e.g. the MongoDB command name such as findAndModify, or the SQL keyword.
Note: 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.
The index of the database being accessed as used in the SELECT command, provided as an integer. To be used instead of the generic db.name attribute.
The name of the primary table that the operation is acting upon, including the schema name (if applicable).
Note: 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.
The database statement being executed.
Note: The value may be sanitized to exclude sensitive information.
An identifier for the database management system (DBMS) product being used. See below for a list of well-known identifiers.
Username for accessing the database.
Username or client_id extracted from the access token or Authorization header in the inbound request from outside the system.
Actual/assumed role the client is making the request under extracted from token or application security context.
Scopes or granted authorities the client currently possesses extracted from token or application security context. The value would come from the scope associated with an OAuth 2.0 Access Token or an attribute value in a SAML 2.0 Assertion.
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.
Note: 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.
The exception message.
A stacktrace as a string in the natural representation for the language runtime. The representation is to be determined and documented by each language SIG.
The type of the exception (its fully-qualified class name, if applicable). The dynamic type of the exception should be preferred over the static type in languages that support it.
A boolean that is true if the serverless function is executed for the first time (aka cold-start).
A string containing the schedule period as Cron Expression.
The name of the source on which the triggering operation was performed. For example, in Cloud Storage or S3 corresponds to the bucket name, and in Cosmos DB to the database name.
The document name/table subjected to the operation. For example, in Cloud Storage or S3 is the name of the file, and in Cosmos DB the table name.
Describes the type of the operation that was performed on the data.
The execution ID of the current function execution.
The name of the invoked function.
Note: SHOULD be equal to the faas.name resource attribute of the invoked function.
The cloud provider of the invoked function.
Note: SHOULD be equal to the cloud.provider resource attribute of the invoked function.
The cloud region of the invoked function.
Note: SHOULD be equal to the cloud.region resource attribute of the invoked function.
Type of the trigger on which the function is executed.
The IP address of the original client behind all proxies, if known (e.g. from X-Forwarded-For).
Note: This is not necessarily the same as net.peer.ip, which would
identify the network-level peer, which may be a proxy.
This attribute should be set when a source of information different
from the one used for net.peer.ip, is available even if that other
source just confirms the same value as net.peer.ip.
Rationale: For net.peer.ip, one typically does not know if it
comes from a proxy, reverse proxy, or the actual client. Setting
http.client_ip when it's the same as net.peer.ip means that
one is at least somewhat confident that the address is not that of
the closest proxy.
Kind of HTTP protocol used.
Note: If net.transport is not specified, it can be assumed to be IP.TCP except if http.flavor is QUIC, in which case IP.UDP is assumed.
The value of the HTTP host header. An empty Host header should also be reported, see note.
Note: When the header is present but empty the attribute SHOULD be set to the empty string. Note that this is a valid situation that is expected in certain cases, according the aforementioned section of RFC 7230. When the header is not set the attribute MUST NOT be set.
HTTP request method.
The size of the request payload body in bytes. This is the number of bytes transferred excluding headers and is often, but not always, present as the Content-Length header. For requests using transport encoding, this should be the compressed size.
The size of the uncompressed request payload body after transport decoding. Not set if transport encoding not used.
The size of the response payload body in bytes. This is the number of bytes transferred excluding headers and is often, but not always, present as the Content-Length header. For requests using transport encoding, this should be the compressed size.
The size of the uncompressed response payload body after transport decoding. Not set if transport encoding not used.
The matched route (path template).
The URI scheme identifying the used protocol.
The primary server name of the matched virtual host. This should be obtained via configuration. If no such configuration can be obtained, this attribute MUST NOT be set ( net.host.name should be used instead).
Note: 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.
The full request target as passed in a HTTP request line or equivalent.
Full HTTP request URL in the form scheme://host[:port]/path?query[#fragment]. Usually the fragment is not transmitted over HTTP, but if it is known, it should be included nevertheless.
Note: http.url MUST NOT contain credentials passed via URL in form of https://username:password@www.example.com/. In such case the attribute's value should be https://www.example.com/.
Value of the HTTP User-Agent header sent by the client.
Compressed size of the message in bytes.
MUST be calculated as two different counters starting from 1 one for sent messages and one for received message.
Note: This way we guarantee that the values will be consistent between different implementations.
Whether this is a received or sent message.
Uncompressed size of the message in bytes.
The identifier for the consumer receiving a message. For Kafka, set it to {messaging.kafka.consumer_group} - {messaging.kafka.client_id}, if both are present, or only messaging.kafka.consumer_group. For brokers, such as RabbitMQ and Artemis, set it to the client_id of the client consuming the message.
The conversation ID identifying the conversation to which the message belongs, represented as a string. Sometimes called "Correlation ID".
The message destination name. This might be equal to the span name but is required nevertheless.
The kind of message destination.
Client Id for the Consumer or Producer that is handling the message.
Name of the Kafka Consumer Group that is handling the message. Only applies to consumers, not producers.
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.
Note: 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.
Partition the message is sent to.
A boolean that is true if the message is a tombstone.
A value used by the messaging system as an identifier for the message, represented as a string.
The compressed size of the message payload in 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.
A string identifying the kind of message consumption as defined in the Operation names section above. If the operation is "send", this attribute MUST NOT be set, since the operation can be inferred from the span kind in that case.
The name of the transport protocol.
The version of the transport protocol.
RabbitMQ message routing key.
A string identifying the messaging system.
A boolean that is true if the message destination is temporary.
Connection string.
The ISO 3166-1 alpha-2 2-character country code associated with the mobile carrier network.
The mobile carrier country code.
The mobile carrier network code.
The name of the mobile carrier.
This describes more details regarding the connection.type. It may be the type of cell technology connection, but it could be used for describing details about a wifi connection.
The internet connection type currently being used by the host.
Like net.peer.ip but for the host IP. Useful in case of a multi-IP host.
Local hostname or similar, see note below.
Like net.peer.port but for the host port.
Remote address of the peer (dotted decimal for IPv4 or RFC5952 for IPv6).
Remote hostname or similar, see note below.
Remote port number.
Transport protocol used. See note below.
The service.name of the remote service. SHOULD be equal to the actual service.name resource attribute of the remote service if any.
The numeric status code of the gRPC request.
error.code property of response if it is an error response.
error.message property of response if it is an error response.
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.
Protocol version as in jsonrpc property of request/response. Since JSON-RPC 1.0 does not specify this, the value can be omitted.
The name of the (logical) method being called, must be equal to the $method part in the span name.
Note: 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).
The full (logical) name of the service being called, including its package name, if applicable.
Note: 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).
A string identifying the remoting system.
Current "managed" thread ID (as opposed to OS thread ID).
Current thread name.
Definition of available values for SemanticAttributes This type is used for backward compatibility, you should use the individual exported constants SemanticAttributes_XXXXX rather than the exported constant map. As any single reference to a constant map value will result in all strings being included into your bundle.
Deprecated
Use the SEMATTRS_XXXXX constants rather than the SemanticAttributes.XXXXX for bundle minification.
