OpenTelemetry SQLAlchemy Instrumentation
Instrument sqlalchemy to report SQL queries.
There are two options for instrumenting code. The first option is to use
the opentelemetry-instrument
executable which will automatically
instrument your SQLAlchemy engine. The second is to programmatically enable
instrumentation via the following code:
SQLCOMMENTER
You can optionally configure SQLAlchemy instrumentation to enable sqlcommenter which enriches the query with contextual information.
Usage
from opentelemetry.instrumentation.sqlalchemy import SQLAlchemyInstrumentor
SQLAlchemyInstrumentor().instrument(enable_commenter=True, commenter_options={})
For example,
Invoking engine.execute("select * from auth_users") will lead to sql query "select * from auth_users" but when SQLCommenter is enabled
the query will get appended with some configurable tags like "select * from auth_users /*tag=value*/;"
SQLCommenter Configurations
We can configure the tags to be appended to the sqlquery log by adding configuration inside commenter_options(default:{}) keyword
db_driver = True(Default) or False
For example, :: Enabling this flag will add any underlying driver like psycopg2 /db_driver=’psycopg2’/
db_framework = True(Default) or False
For example, :: Enabling this flag will add db_framework and it’s version /db_framework=’sqlalchemy:0.41b0’/
opentelemetry_values = True(Default) or False
For example, :: Enabling this flag will add traceparent values /traceparent=’00-03afa25236b8cd948fa853d67038ac79-405ff022e8247c46-01’/
Usage
from sqlalchemy import create_engine
from opentelemetry.instrumentation.sqlalchemy import SQLAlchemyInstrumentor
import sqlalchemy
engine = create_engine("sqlite:///:memory:")
SQLAlchemyInstrumentor().instrument(
engine=engine,
)
# of the async variant of SQLAlchemy
from sqlalchemy.ext.asyncio import create_async_engine
from opentelemetry.instrumentation.sqlalchemy import SQLAlchemyInstrumentor
import sqlalchemy
engine = create_async_engine("sqlite:///:memory:")
SQLAlchemyInstrumentor().instrument(
engine=engine.sync_engine
)
API
- class opentelemetry.instrumentation.sqlalchemy.SQLAlchemyInstrumentor(*args, **kwargs)[source]
Bases:
BaseInstrumentor
An instrumentor for SQLAlchemy See 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.
