OpenTelemetry mysqlclient Instrumentation
The integration with MySQLClient supports the MySQLClient library and can be enabled
by using MySQLClientInstrumentor.
Usage
import MySQLdb
from opentelemetry.instrumentation.mysqlclient import MySQLClientInstrumentor
MySQLClientInstrumentor().instrument()
cnx = MySQLdb.connect(database="MySQL_Database")
cursor = cnx.cursor()
cursor.execute("CREATE TABLE IF NOT EXISTS test (testField INTEGER)")
cursor.execute("INSERT INTO test (testField) VALUES (123)")
cnx.commit()
cursor.close()
cnx.close()
Configuration
SQLCommenter
You can optionally enable sqlcommenter which enriches the query with contextual
information. Queries made after setting up trace integration with sqlcommenter
enabled will have configurable key-value pairs appended to them, e.g.
"select * from auth_users; /*traceparent=00-01234567-abcd-01*/". This
supports context propagation between database client and server when database log
records are enabled. For more information, see:
import MySQLdb
from opentelemetry.instrumentation.mysqlclient import MySQLClientInstrumentor
MySQLClientInstrumentor().instrument(enable_commenter=True)
cnx = MySQLdb.connect(database="MySQL_Database")
cursor = cnx.cursor()
cursor.execute("CREATE TABLE IF NOT EXISTS test (testField INTEGER)")
cursor.execute("INSERT INTO test (testField) VALUES (123)")
cnx.commit()
cursor.close()
cnx.close()
SQLCommenter with commenter_options
The key-value pairs appended to the query can be configured using
commenter_options. When sqlcommenter is enabled, all available KVs/tags
are calculated by default. commenter_options supports opting out
of specific KVs.
import MySQLdb
from opentelemetry.instrumentation.mysqlclient import MySQLClientInstrumentor
# Opts into sqlcomment for MySQLClient trace integration.
# Opts out of tags for mysql_client_version, db_driver.
MySQLClientInstrumentor().instrument(
enable_commenter=True,
commenter_options={
"mysql_client_version": False,
"db_driver": False,
}
)
Available commenter_options
The following sqlcomment key-values can be opted out of through commenter_options:
Commenter Option |
Description |
Example |
|---|---|---|
|
Database driver name with version (URL encoded). |
|
|
DB-API threadsafety value: 0-3 or unknown. |
|
|
DB-API API level: 1.0, 2.0, or unknown. |
|
|
DB-API paramstyle for SQL statement parameter. |
|
|
MySQL client version. |
|
|
OpenTelemetry context as traceparent at time of query. |
|
SQLComment in span attribute
If sqlcommenter is enabled, you can opt into the inclusion of sqlcomment in
the query span db.statement attribute for your needs. If commenter_options
have been set, the span attribute comment will also be configured by this
setting.
from opentelemetry.instrumentation.mysqlclient import MySQLClientInstrumentor
# Opts into sqlcomment for mysqlclient trace integration.
# Opts into sqlcomment for `db.statement` and/or `db.query.text` span attribute.
MySQLClientInstrumentor().instrument(
enable_commenter=True,
enable_attribute_commenter=True,
)
Warning
Capture of sqlcomment in db.statement/db.query.text may have high cardinality without platform normalization. See Semantic Conventions for database spans for more information.
API
- class opentelemetry.instrumentation.mysqlclient.MySQLClientInstrumentor(*args, **kwargs)[source]
Bases:
BaseInstrumentor- instrumentation_dependencies()[source]
Return a list of python packages with versions that the will be instrumented.
The format should be the same as used in requirements.txt or pyproject.toml.
For example, if an instrumentation instruments requests 1.x, this method should look like: :rtype:
Collection[str]- def instrumentation_dependencies(self) -> Collection[str]:
return [‘requests ~= 1.0’]
This will ensure that the instrumentation will only be used when the specified library is present in the environment.
- static instrument_connection(connection, tracer_provider=None, enable_commenter=None, commenter_options=None, enable_attribute_commenter=None)[source]
Enable instrumentation in a mysqlclient connection.
- Parameters:
connection – The MySQL connection instance to instrument. This connection is typically created using MySQLdb.connect() and needs to be wrapped to collect telemetry.
tracer_provider – A custom TracerProvider instance to be used for tracing. If not specified, the globally configured tracer provider will be used.
enable_commenter – A flag to enable the OpenTelemetry SQLCommenter feature. If set to True, SQL queries will be enriched with contextual information (e.g., database client details). Default is None.
commenter_options –
A dictionary of configuration options for SQLCommenter. All options are enabled (True) by default. This allows you to customize metadata appended to queries. Possible options include:
db_driver: Adds the database driver name and version.
dbapi_threadsafety: Adds threadsafety information.
dbapi_level: Adds the DB-API version.
mysql_client_version: Adds the MySQL client version.
driver_paramstyle: Adds the parameter style.
opentelemetry_values: Includes traceparent values.
- Returns:
An instrumented MySQL connection with OpenTelemetry support enabled.
