Database

Generic Database Attributes

Attribute	Type	Description	Examples	Stability
db.instance.id	string	An identifier (address, unique name, or any other identifier) of the database instance that is executing queries or mutations on the current connection. This is useful in cases where the database is running in a clustered environment and the instrumentation is able to record the node executing the query. The client may obtain this value in databases like MySQL using queries like select @@hostname.	mysql-e26b99z.example.com
db.name	string	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). [1]	customers; main
db.operation	string	The name of the operation being executed, e.g. the MongoDB command name such as findAndModify, or the SQL keyword. [2]	findAndModify; HMSET; SELECT
db.statement	string	The database statement being executed.	SELECT * FROM wuser_table; SET mykey "WuValue"
db.system	string	An identifier for the database management system (DBMS) product being used. See below for a list of well-known identifiers.	other_sql
db.user	string	Username for accessing the database.	readonly_user; reporting_user

[1]: In some SQL databases, the database name to be used is called “schema name”. In case there are multiple layers that could be considered for database name (e.g. Oracle instance name and schema name), the database name to be used is the more specific layer (e.g. Oracle schema name).

[2]: 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.system has the following list of well-known values. If one of them applies, then the respective value MUST be used; otherwise, a custom value MAY be used.

Cassandra Attributes

Attribute	Type	Description	Examples	Stability
db.cassandra.consistency_level	string	The consistency level of the query. Based on consistency values from CQL.	all
db.cassandra.coordinator.dc	string	The data center of the coordinating node for a query.	us-west-2
db.cassandra.coordinator.id	string	The ID of the coordinating node for a query.	be13faa2-8574-4d71-926d-27f16cf8a7af
db.cassandra.idempotence	boolean	Whether or not the query is idempotent.
db.cassandra.page_size	int	The fetch size used for paging, i.e. how many rows will be returned at once.	5000
db.cassandra.speculative_execution_count	int	The number of times a query was speculatively executed. Not set or 0 if the query was not executed speculatively.	0; 2
db.cassandra.table	string	The name of the primary Cassandra table that the operation is acting upon, including the keyspace name (if applicable). [1]	mytable

[1]: 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.consistency_level MUST be one of the following:

Value	Description	Stability
all	all
each_quorum	each_quorum
quorum	quorum
local_quorum	local_quorum
one	one
two	two
three	three
local_one	local_one
any	any

[1]: Many Elasticsearch url paths allow dynamic values. These SHOULD be recorded in span attributes in the format db.elasticsearch.path_parts.<key>, where <key> is the url path part name. The implementation SHOULD reference the elasticsearch schema in order to map the path part values to their names.

Attribute	Type	Description	Examples	Stability
db.redis.database_index	int	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.	0; 1; 15
