General Database Attributes

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

Attribute	Type	Description	Examples	Stability
db.client.connection.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 parameters that would make the name unique, for example, combining attributes server.address, server.port, and db.namespace, formatted as server.address:server.port/db.namespace. Instrumentations that generate connection pool name following different patterns SHOULD document it.	myDataSource
db.client.connection.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.batch.size	int	The number of queries included in a batch operation. [3]	2; 3; 4
db.operation.name	string	The name of the operation or command being executed. [4]	findAndModify; HMSET; SELECT
db.operation.parameter.<key>	string	A database operation parameter, with <key> being the parameter name, and the attribute value being a string representation of the parameter value. [5]	someval; 55
db.query.parameter.<key>	string	A database query parameter, with <key> being the parameter name, and the attribute value being a string representation of the parameter value. [6]	someval; 55
db.query.summary	string	Low cardinality summary of a database query. [7]	SELECT wuser_table; INSERT shipping_details SELECT orders; get user by id
db.query.text	string	The database query being executed. [8]	SELECT * FROM wuser_table where username = ?; SET mykey ?
db.response.returned_rows	int	Number of rows returned by the operation.	10; 30; 1000
db.response.status_code	string	Database response status code. [9]	102; ORA-17002; 08P01; 404
db.stored_procedure.name	string	The name of a stored procedure within the database. [10]	GetCustomer
db.system.name	string	The database management system (DBMS) product as identified by the client instrumentation. [11]	other_sql; softwareag.adabas; actian.ingres

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

The collection name SHOULD NOT be extracted from db.query.text, when the database system supports query text with multiple collections in non-batch operations.

For batch operations, if the individual operations are known to have the same collection name then that collection name SHOULD be used.

[2] db.namespace: If a database system has multiple namespace components, they SHOULD be concatenated from the most general to the most specific namespace component, using | as a separator between the components. Any missing components (and their associated separators) SHOULD be omitted. 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] db.operation.batch.size: Operations are only considered batches when they contain two or more operations, and so db.operation.batch.size SHOULD never be 1.

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

The operation name SHOULD NOT be extracted from db.query.text, when the database system supports query text with multiple operations in non-batch operations.

If spaces can occur in the operation name, multiple consecutive spaces SHOULD be normalized to a single space.

For batch operations, if the individual operations are known to have the same operation name then that operation name SHOULD be used prepended by BATCH , otherwise db.operation.name SHOULD be BATCH or some other database system specific term if more applicable.

[5] db.operation.parameter.<key>: For example, a client-side maximum number of rows to read from the database MAY be recorded as the db.operation.parameter.max_rows attribute.

db.query.text parameters SHOULD be captured using db.query.parameter.<key> instead of db.operation.parameter.<key>.

[6] db.query.parameter.<key>: If a query parameter has no name and instead is referenced only by index, then <key> SHOULD be the 0-based index.

db.query.parameter.<key> SHOULD match up with the parameterized placeholders present in db.query.text.

db.query.parameter.<key> SHOULD NOT be captured on batch operations.

Examples:

• For a query SELECT * FROM users where username = %s with the parameter "jdoe", the attribute db.query.parameter.0 SHOULD be set to "jdoe".

• For a query "SELECT * FROM users WHERE username = %(username)s; with parameter username = "jdoe", the attribute db.query.parameter.username SHOULD be set to "jdoe".

[7] db.query.summary: The query summary describes a class of database queries and is useful as a grouping key, especially when analyzing telemetry for database calls involving complex queries.

Summary may be available to the instrumentation through instrumentation hooks or other means. If it is not available, instrumentations that support query parsing SHOULD generate a summary following Generating query summary section.

[8] db.query.text: For sanitization see Sanitization of db.query.text. For batch operations, if the individual operations are known to have the same query text then that query text SHOULD be used, otherwise all of the individual query texts SHOULD be concatenated with separator ; or some other database system specific separator if more applicable. Parameterized query text SHOULD NOT be sanitized. Even though parameterized query text can potentially have sensitive data, by using a parameterized query the user is giving a strong signal that any sensitive data will be passed as parameter values, and the benefit to observability of capturing the static part of the query text by default outweighs the risk.

[9] db.response.status_code: The status code returned by the database. Usually it represents an error code, but may also represent partial success, warning, or differentiate between various types of successful outcomes. Semantic conventions for individual database systems SHOULD document what db.response.status_code means in the context of that system.

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

For batch operations, if the individual operations are known to have the same stored procedure name then that stored procedure name SHOULD be used.

[11] db.system.name: 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.name is set to postgresql based on the instrumentation’s best knowledge.

db.client.connection.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.
