Db Attributes

This group defines the attributes used to describe telemetry in the context of databases.

Attribute	Type	Description	Examples	Stability
db.client.connections.pool.name	string	The name of the connection pool; unique within the instrumented application. In case the connection pool implementation doesn’t provide a name, instrumentation should use a combination of server.address and server.port attributes formatted as server.address:server.port.	myDataSource
db.client.connections.state	string	The state of a connection in the pool	idle
db.collection.name	string	The name of a collection (table, container) within the database. [1]	public.users; customers
db.namespace	string	The name of the database, fully qualified within the server address and port. [2]	customers; test.users
db.operation.name	string	The name of the operation or command being executed. [3]	findAndModify; HMSET; SELECT
db.query.parameter.<key>	string	The query parameters used in db.query.text, with <key> being the parameter name, and the attribute value being the parameter value. [4]	someval; 55
db.query.text	string	The database query being executed.	SELECT * FROM wuser_table where username = ?; SET mykey "WuValue"
db.system	string	The database management system (DBMS) product as identified by the client instrumentation. [5]	other_sql; mssql; mssqlcompact

[1]: If the collection name is parsed from the query, it SHOULD match the value provided in the query and may be qualified with the schema and database name. It is RECOMMENDED to capture the value as provided by the application without attempting to do any case normalization.

[2]: If a database system has multiple namespace components, they SHOULD be concatenated (potentially using database system specific conventions) from most general to most specific namespace component, and more specific namespaces SHOULD NOT be captured without the more general namespaces, to ensure that “startswith” queries for the more general namespaces will be valid. Semantic conventions for individual database systems SHOULD document what db.namespace means in the context of that system. It is RECOMMENDED to capture the value as provided by the application without attempting to do any case normalization.

[3]: It is RECOMMENDED to capture the value as provided by the application without attempting to do any case normalization.

[4]: Query parameters should only be captured when db.query.text is parameterized with placeholders. If a parameter has no name and instead is referenced only by index, then <key> SHOULD be the 0-based index.

[5]: The actual DBMS may differ from the one identified by the client. For example, when using PostgreSQL client libraries to connect to a CockroachDB, the db.system is set to postgresql based on the instrumentation’s best knowledge.

db.client.connections.state 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.
