A new priority sampler is available, unlike the other sampler which is only based on a local rate, this one uses feedback from the agent to decide wether a given trace should be sampled or not. It is still possible to use the historical sampler also, this one operates later in the pipeline. Whenever a trace should be sampled, an attribute is set which is a message for the downstream backend that "this should be kept, no matter what" and conversely, the same attribute can be set to state that "this should be used for stats, but not be kept as a trace". The decision is made very early in the pipeline, when the root span is created. The attribute is then propagated through all calls, local or remote. By default, this feature is disabled, is has to be explicitely activated by passing 'priority_sampling = True' to configure(). --- ddtrace/api.py | 59 +++++--- ddtrace/constants.py | 1 + ddtrace/context.py | 49 +++++-- ddtrace/contrib/aiohttp/middlewares.py | 32 +++-- ddtrace/contrib/asyncio/helpers.py | 16 +-- ddtrace/contrib/asyncio/provider.py | 2 - ddtrace/sampler.py | 112 ++++++++------- ddtrace/span.py | 36 +++++ ddtrace/tracer.py | 96 +++++++++---- ddtrace/writer.py | 16 ++- tests/contrib/aiohttp/test_middleware.py | 62 ++++++++ tests/contrib/celery/test_task.py | 64 +++------ tests/test_context.py | 2 +- tests/test_encoders.py | 6 + tests/test_integration.py | 33 +++++ tests/test_sampler.py | 171 ++++++++++------------- tests/test_span.py | 67 ++++++++- 17 files changed, 533 insertions(+), 291 deletions(-) diff --git a/ddtrace/api.py b/ddtrace/api.py index 1db81454b5..293e4a3d2e 100644 --- a/ddtrace/api.py +++ b/ddtrace/api.py @@ -12,28 +12,59 @@ TRACE_COUNT_HEADER = 'X-Datadog-Trace-Count' +_VERSIONS = {'v0.4': {'traces': '/v0.4/traces', + 'services': '/v0.4/services', + 'compatibility_mode': False, + 'fallback': 'v0.3'}, + 'v0.3': {'traces': '/v0.3/traces', + 'services': '/v0.3/services', + 'compatibility_mode': False, + 'fallback': 'v0.2'}, + 'v0.2': {'traces': '/v0.2/traces', + 'services': '/v0.2/services', + 'compatibility_mode': True, + 'fallback': None}} + class API(object): """ Send data to the trace agent using the HTTP protocol and JSON format """ - def __init__(self, hostname, port, headers=None, encoder=None): + def __init__(self, hostname, port, headers=None, encoder=None, priority_sampling=False): self.hostname = hostname self.port = port - self._traces = '/v0.3/traces' - self._services = '/v0.3/services' - self._compatibility_mode = False - self._encoder = encoder or get_encoder() - # overwrite the Content-type with the one chosen in the Encoder self._headers = headers or {} + self._version = None + + if priority_sampling: + self._set_version('v0.4', encoder=encoder) + else: + self._set_version('v0.3', encoder=encoder) + self._headers.update({ - 'Content-Type': self._encoder.content_type, 'Datadog-Meta-Lang': 'python', 'Datadog-Meta-Lang-Version': PYTHON_VERSION, 'Datadog-Meta-Lang-Interpreter': PYTHON_INTERPRETER, 'Datadog-Meta-Tracer-Version': ddtrace.__version__, }) + def _set_version(self, version, encoder=None): + if version not in _VERSIONS: + version = 'v0.2' + if version == self._version: + return + self._version = version + self._traces = _VERSIONS[version]['traces'] + self._services = _VERSIONS[version]['services'] + self._fallback = _VERSIONS[version]['fallback'] + self._compatibility_mode = _VERSIONS[version]['compatibility_mode'] + if self._compatibility_mode: + self._encoder = JSONEncoder() + else: + self._encoder = encoder or get_encoder() + # overwrite the Content-type with the one chosen in the Encoder + self._headers.update({'Content-Type': self._encoder.content_type}) + def _downgrade(self): """ Downgrades the used encoder and API level.

Here is +an example assuming that you have `rpc.call` function that call a `method` and +propagate a `rpc_metadata` dictionary over the wire:: + + + # Implement your own context propagator + class MyRPCPropagator(object): + def inject(self, span_context, rpc_metadata): + rpc_metadata.update({ + 'trace_id': span_context.trace_id, + 'span_id': span_context.span_id, + 'sampling_priority': span_context.sampling_priority, + }) + + def extract(self, rpc_metadata): + return Context( + trace_id=rpc_metadata['trace_id'], + span_id=rpc_metadata['span_id'], + sampling_priority=rpc_metadata['sampling_priority'], + ) + + # On the parent side + def parent_rpc_call(): + with tracer.trace("parent_span") as span: + rpc_metadata = {} + propagator = MyRPCPropagator() + propagator.inject(span.context, rpc_metadata) + method = "" + rpc.call(method, metadata) + + # On the child side + def child_rpc_call(method, rpc_metadata): + propagator = MyRPCPropagator() + context = propagator.extract(rpc_metadata) + tracer.context_provider.activate(context) + + with tracer.trace("child_span") as span: + span.set_meta('my_rpc_method', method) + + +Sampling +-------- + +.. _`Priority Sampling`: + +Priority Sampling +^^^^^^^^^^^^^^^^^ + +To learn about what sampling is check out our documentation `here +`_. + +By default priorities are set on a trace by a sampler. The sampler can set the +priority to the following values: + +- ``AUTO_REJECT``: the sampler automatically rejects the trace +- ``AUTO_KEEP``: the sampler automatically keeps the trace + +Priority sampling is disabled by default. Enabling it ensures that your sampled +distributed traces will be complete. To enable priority sampling:: + + tracer.configure(priority_sampling=True) + +Once enabled, the sampler will automatically assign a priority to your traces, +depending on their service and volume. + +You can also set this priority manually to either drop an uninteresting trace or +to keep an important one. +To do this, set the ``context.sampling_priority`` to one of the following: + +- ``USER_REJECT``: the user asked to reject the trace +- ``USER_KEEP``: the user asked to keep the trace + +When not using distributed tracing, you may change the priority at any time, as +long as the trace is not finished yet. +But it has to be done before any context propagation (fork, RPC calls) to be +effective in a distributed context. +Changing the priority after context has been propagated causes different parts +of a distributed trace to use different priorities. Some parts might be kept, +some parts might be rejected, and this can cause the trace to be partially +stored and remain incomplete. + +If you change the priority, we recommend you do it as soon as possible, when the +root span has just been created:: + + from ddtrace.ext.priority import USER_REJECT, USER_KEEP + + context = tracer.context_provider.active() + + # indicate to not keep the trace + context.sampling_priority = USER_REJECT + + +Client Sampling +^^^^^^^^^^^^^^^ + +Client sampling enables the sampling of traces before they are sent to the +Agent. This can provide some performance benefit as the traces will be +dropped in the client. + +The ``RateSampler`` randomly samples a percentage of traces:: + + from ddtrace.sampler import RateSampler + + # Sample rate is between 0 (nothing sampled) to 1 (everything sampled). + # Keep 20% of the traces. + sample_rate = 0.2 + tracer.sampler = RateSampler(sample_rate) + + +Resolving deprecation warnings +------------------------------ +Before upgrading, it’s a good idea to resolve any deprecation warnings raised by your project. +These warnings must be fixed before upgrading, otherwise the ``ddtrace`` library +will not work as expected. Our deprecation messages include the version where +the behavior is altered or removed. + +In Python, deprecation warnings are silenced by default. To enable them you may +add the following flag or environment variable:: + + $ python -Wall app.py + + # or + + $ PYTHONWARNINGS=all python app.py + + +Trace Filtering +--------------- + +It is possible to filter or modify traces before they are sent to the Agent by +configuring the tracer with a filters list. For instance, to filter out +all traces of incoming requests to a specific url:: + + Tracer.configure(settings={ + 'FILTERS': [ + FilterRequestsOnUrl(r'http://test\.example\.com'), + ], + }) + +All the filters in the filters list will be evaluated sequentially +for each trace and the resulting trace will either be sent to the Agent or +discarded depending on the output. + +**Use the standard filters** + +The library comes with a ``FilterRequestsOnUrl`` filter that can be used to +filter out incoming requests to specific urls: + +.. autoclass:: ddtrace.filters.FilterRequestsOnUrl + :members: + +**Write a custom filter** + +Creating your own filters is as simple as implementing a class with a +``process_trace`` method and adding it to the filters parameter of +Tracer.configure. process_trace should either return a trace to be fed to the +next step of the pipeline or ``None`` if the trace should be discarded:: + + class FilterExample(object): + def process_trace(self, trace): + # write here your logic to return the `trace` or None; + # `trace` instance is owned by the thread and you can alter + # each single span or the whole trace if needed + + # And then instantiate it with + filters = [FilterExample()] + Tracer.configure(settings={'FILTERS': filters}) + +(see filters.py for other example implementations) + + +.. _ddtracerun: + +``ddtrace-run`` +--------------- + +``ddtrace-run`` will trace :ref:`supported` web frameworks +and database modules without the need for changing your code:: + + $ ddtrace-run -h + + Execute the given Python program, after configuring it + to emit Datadog traces. + + Append command line arguments to your program as usual. + + Usage: [ENV_VARS] ddtrace-run + + +The available environment variables for ``ddtrace-run`` are: + +* ``DATADOG_TRACE_ENABLED=true|false`` (default: true): Enable web framework and + library instrumentation.

Our deprecation messages include the version where the behavior is altered or -removed. - -In Python, deprecation warnings are silenced by default, and to turn them on you may add the -following flag or environment variable:: - - $ python -Wall app.py - - # or - - $ PYTHONWARNINGS=all python app.py - - -Advanced Usage --------------- - -Trace Filtering -~~~~~~~~~~~~~~~ - -It is possible to filter or modify traces before they are sent to the agent by -configuring the tracer with a filters list. For instance, to filter out -all traces of incoming requests to a specific url:: - - Tracer.configure(settings={ - 'FILTERS': [ - FilterRequestsOnUrl(r'http://test\.example\.com'), - ], - }) - -All the filters in the filters list will be evaluated sequentially -for each trace and the resulting trace will either be sent to the agent or -discarded depending on the output. - -**Use the standard filters** - -The library comes with a FilterRequestsOnUrl filter that can be used to -filter out incoming requests to specific urls: - -.. autoclass:: ddtrace.filters.FilterRequestsOnUrl - :members: - -**Write a custom filter** - -Creating your own filters is as simple as implementing a class with a -process_trace method and adding it to the filters parameter of -Tracer.configure. process_trace should either return a trace to be fed to the -next step of the pipeline or None if the trace should be discarded:: - - class FilterExample(object): - def process_trace(self, trace): - # write here your logic to return the `trace` or None; - # `trace` instance is owned by the thread and you can alter - # each single span or the whole trace if needed - - # And then instantiate it with - filters = [FilterExample()] - Tracer.configure(settings={'FILTERS': filters}) - -(see filters.py for other example implementations) - - -API -~~~ - -.. autoclass:: ddtrace.Tracer - :members: - :special-members: __init__ - - -.. autoclass:: ddtrace.Span - :members: - :special-members: __init__ - -.. autoclass:: ddtrace.Pin - :members: - :special-members: __init__ - -.. autofunction:: ddtrace.monkey.patch_all - -.. autofunction:: ddtrace.monkey.patch - -.. toctree:: - :maxdepth: 2 - -.. _integrations: - -Glossary -~~~~~~~~ - -**Service** - -The name of a set of processes that do the same job. Some examples are :code:`datadog-web-app` or :code:`datadog-metrics-db`. In general, you only need to set the -service in your application's top level entry point. - -**Resource** - -A particular query to a service. For a web application, some -examples might be a URL stem like :code:`/user/home` or a handler function -like :code:`web.user.home`. For a SQL database, a resource -would be the sql of the query itself like :code:`select * from users -where id = ?`. - -You can track thousands (not millions or billions) of unique resources per services, so prefer -resources like :code:`/user/home` rather than :code:`/user/home?id=123456789`. - -**App** - -Currently, an "app" doesn't provide much functionality and is subject to change in the future. For example, in the UI, hovering over the type icon (Web/Database/Custom) will display the “app” for a particular service. In the future the UI may use "app" as hints to group services together better and surface relevant metrics. - -**Span** - -A span tracks a unit of work in a service, like querying a database or -rendering a template. Spans are associated with a service and optionally a -resource. A span has a name, start time, duration and optional tags. - -Supported versions -================== - We officially support Python 2.7, 3.4 and above. -+---------------------+--------------------+ -| Integrations | Supported versions | -+=====================+====================+ -| aiohttp | >= 1.2 | -+---------------------+--------------------+ -| aiobotocore | >= 0.2.3 | -+---------------------+--------------------+ -| aiopg | >= 0.12.0 | -+---------------------+--------------------+ -| boto | >= 2.29.0 | -+---------------------+--------------------+ -| botocore | >= 1.4.51 | -+---------------------+--------------------+ -| bottle | >= 0.11 | -+---------------------+--------------------+ -| celery | >= 3.1 | -+---------------------+--------------------+ -| cassandra | >= 3.5 | -+---------------------+--------------------+ -| djangorestframework | >= 3.4 | -+---------------------+--------------------+ -| django | >= 1.8 | -+---------------------+--------------------+ -| elasticsearch | >= 1.6 | -+---------------------+--------------------+ -| falcon | >= 1.0 | -+---------------------+--------------------+ -| flask | >= 0.10 | -+---------------------+--------------------+ -| flask_cache | >= 0.12 | -+---------------------+--------------------+ -| gevent | >= 1.0 | -+---------------------+--------------------+ -| mongoengine | >= 0.11 | -+---------------------+--------------------+ -| mysql-connector | >= 2.1 | -+---------------------+--------------------+ -| MySQL-python | >= 1.2.3 | -+---------------------+--------------------+ -| mysqlclient | >= 1.3 | -+---------------------+--------------------+ -| psycopg2 | >= 2.4 | -+---------------------+--------------------+ -| pylibmc | >= 1.4 | -+---------------------+--------------------+ -| pylons | >= 0.9.6 | -+---------------------+--------------------+ -| pymongo | >= 3.0 | -+---------------------+--------------------+ -| pymemcache | >= 1.3 | -+---------------------+--------------------+ -| pyramid | >= 1.7 | -+---------------------+--------------------+ -| redis | >= 2.6 | -+---------------------+--------------------+ -| sqlalchemy | >= 1.0 | -+---------------------+--------------------+ -| tornado | >= 4.0 | -+---------------------+--------------------+ +The versions listed are the versions that we have tested, but ``ddtrace`` can +still be compatible with other versions of these libraries.

Which is much more fast (~50%).

(#607) * [tests] Update the integrations libraries versions to the latest possible. A few notes follow for specific libraries besides updates you can see in the code itself *tornado* - not possible to udate to 5.x, postponing *elasticsearch* - added 6.3 - a test had to be updated because `doc_type` arg was optional before, it is not anymore. *falcon* - added 1.3, 1.4 - a small change to a test class was necessaries because of a new expected property that must exists in the TestCase class. *flask* - added version 1.0 - our integration flask_cache does not support flask 1. *pymongo/mongoengine* - mongoengine: updated to latest - pymongo: added 3.6. Latest stable is 3.7, but our integration fails to trace at least inserts. Example: 1) ['count here.are.songs', 'count here.are.songs', 'count here.are.songs', 'count here.are.songs', 'delete here.are.songs {"artist": "?"}', 'delete here.are.songs {"artist": "?"}', 'drop here.are.songs', 'insert here.are.songs'] 2) [u'count here.are.songs', u'count here.are.songs', u'count here.are.songs', u'count here.are.songs', u'delete here.are.songs {"artist": "?"}', u'delete here.are.songs {"artist": "?"}', u'drop here.are.songs'] * [tests] Fix dependecy line aiobotocore->aiohttp->multidict after release of multidict 4.4 Suddenly master started to fail when before was passing just fine. The difference in the dependency tree showed that the only package updated was multidict. Fails : aiobotocore==0.2.3,aiohttp==1.3.5,...,multidict==4.4.1,...,yarl==0.9.8 Succeed: aiobotocore==0.2.3,aiohttp==1.3.5,...,multidict==4.3.1,...yarl==0.9.8 The versions we are testing are pretty old and they are not compatible with multidict 4.4.x that was just released a few days ago.

In this case + # binding will have been performed where the instance against + # which the method is bound will be None at that point. + # + # This case is a problem because we can no longer tell if the + # method was a static method, plus if using Python3, we cannot + # tell if it was an instance method as the concept of an + # unnbound method no longer exists. + # + # 4.

It is also only an issue + # if a decorator wants to actually do things with the arguments. + # + # As to not being able to identify static methods properly, we + # just hope that that isn't something people are going to want + # to wrap, or if they do suggest they do it the correct way by + # ensuring that it is decorated in the class definition itself, + # or patch it in the __dict__ of the class type. + # + # So to get the best outcome we can, whenever we aren't sure what + # it is, we label it as a 'function'.

[PATCH 1762/1981] [core] Collect run-time metrics (#819) * [metrics] initial implementation - add data structures with tests - add collectors for psutil and platform modules - send metrics to agent statsd * [metrics] add gc generation metrics * [metrics] clean-up * [metrics] add thread worker, additional metrics * [metrics] linting * [metrics] code organization * [metrics] add runtime_id to tracer * [metrics] resolve rebase conflicts * [metrics] linting * [metrics] add runtime-id tag * [metrics] linting * [metrics] linting * Add environment variable for enabling runtime metrics * Environment configuration for dogstatsd * apply brettlinter - thanks brett :) Co-Authored-By: Kyle-Verhoog * [metrics] remove unnecessary LazyValues * [metrics] in-line psutil method calls * [metrics] use internal logger * [metrics] add reset method, gather services * [metrics] support multiple services properly * [metrics] use base test case * [metrics] handle process forking * [metrics] add runtime metrics tags to spans * Remove LazyValue * Add dependencies for runtime metrics to library * Refactor metrics collectors and add tests * Begin major refactoring of api * Decouple dogstatsd from runtime metrics * Fix constant * Fix flake8 * Separate host/port for trace agent and dogstatsd * Update ddtrace_run tests * Fix integration test * Vendor datadogpy to fix issues with gevent+requests * Revert change to on import * Add license for dogstatsd * Move runtime metrics into internal * Fixes for ddtrace.internal.runtime * Wrap worker flush in try-except to log errors * Flush calls gauge which is a UDP so no need to catch errors * Remove unused datadog and metrics tests * Rename class in repr * Remove collect_fn argument from ValueCollector * Fix flake8 * Remove tags not called for in RFC * Better metric names for cpu * Use 0-1-2 for gc collections * Comments * Fix daemon for threading * Add test on metrics received by dogstatsd * Remove datadog dependency since we have it vendored * Fix cpu metrics * Fix cumulative metrics * Fix reset * Flag check unnecessary * Fix runtime tag names Co-Authored-By: majorgreys * Only tag root span with runtime info * Use common namespace for gc metric names * Remove unnecessary set check * Wait for tests of metrics received * Fix for constant tags and services * Fix broken config * Fix flake8 * Fix ddtrace-run test for runtime metrics enabled * Update ddtrace/bootstrap/sitecustomize.py Co-Authored-By: majorgreys --- ddtrace/bootstrap/sitecustomize.py | 2 + ddtrace/internal/runtime/__init__.py | 12 +

Proper documentation must be written. + +Splitting Pull Requests +======================= + +If you discussed your feature within an issue (as advised), there's a great +chance that the implementation appears doable in several steps. In order to +facilite the review process, we strongly advise to split your feature +implementation in small pull requests (if that is possible) so they contain a +very small number of commits (a single commit per pull request being optimal). + +That ensures that: + +1.

Therefore, support for old versions of a library might be +dropped from the testing pipeline at anytime. + +Code Style +========== + +The code style is enforced by `flake8 `_, its +configuration, and possibly extensions. No code style review should be done by +a human. All code style enforcement must be automatized to avoid bikeshedding +and losing time. diff --git a/docs/index.rst b/docs/index.rst index 19ba83b02b..8ce7ae2609 100644 --- a/docs/index.rst +++ b/docs/index.rst @@ -141,3 +141,4 @@ Indices and tables other_integrations basic_usage advanced_usage + contributing From 1b66566a3c0e60aae7ac7dc6b11e7152d866f573 Mon Sep 17 00:00:00 2001 From: Martin Ringehahn Date: Fri, 24 May 2019 11:42:27 -0400 Subject: [PATCH 1805/1981] make psutil requirement more accurate PSUtilRuntimeMetricCollector uses `.oneshot` which only comes with version 5 or higher. --- setup.py | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/setup.py b/setup.py index f0ee1e2845..b18d013574 100644 --- a/setup.py +++ b/setup.py @@ -86,7 +86,7 @@ def run_tests(self): license='BSD', packages=find_packages(exclude=['tests*']), install_requires=[ - 'psutil', + 'psutil>=5.0.0', ], extras_require={ # users can include opentracing by having: From f1b20af7a8921f9a4d2458dcdbcaf166adb4efd2 Mon Sep 17 00:00:00 2001 From: Martin Ringehahn Date: Tue, 28 May 2019 14:13:50 -0400 Subject: [PATCH 1806/1981] fix documentation for current_root_span the function may return `None`. guard against that in the example --- ddtrace/tracer.py | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/ddtrace/tracer.py b/ddtrace/tracer.py index ce5088137d..55f0c7fbd5 100644 --- a/ddtrace/tracer.py +++ b/ddtrace/tracer.py @@ -387,7 +387,8 @@ def current_root_span(self): # get the root span root_span = tracer.current_root_span() # set the host just once on the root span - root_span.set_tag('host', '127.0.0.1') + if root_span: + root_span.set_tag('host', '127.0.0.1') """ ctx = self.get_call_context() if ctx: From 2f3bb75019e100bf3bdbcdd556b40a09b27e3019 Mon Sep 17 00:00:00 2001 From: Julien Danjou Date: Fri, 31 May 2019 14:22:34 +0200 Subject: [PATCH 1807/1981] tox: fix ignore path for integrations tests/integration does not exists; the file tests/test_integration.py is more likely what we want to ignore. --- tox.ini | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tox.ini b/tox.ini index 5af82ed1db..68e1150f97 100644 --- a/tox.ini +++ b/tox.ini @@ -323,7 +323,7 @@ passenv=TEST_* commands = # run only essential tests related to the tracing client - tracer: pytest {posargs} --ignore="tests/contrib" --ignore="tests/integration" --ignore="tests/commands" --ignore="tests/opentracer" --ignore="tests/unit" --ignore="tests/internal" tests + tracer: pytest {posargs} --ignore="tests/contrib" --ignore="tests/test_integration.py" --ignore="tests/commands" --ignore="tests/opentracer" --ignore="tests/unit" --ignore="tests/internal" tests # run only the `ddtrace.internal` tests internal: pytest {posargs} tests/internal # run only the opentrace tests From fd8c25af533636e3ec05d25332d4099f5e01f26b Mon Sep 17 00:00:00 2001 From: Julien Danjou Date: Fri, 31 May 2019 15:18:03 +0200 Subject: [PATCH 1808/1981] api: simplify _put codepath MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The length is always provided and should be included in every request, so make it mandatory.

This should divide the number of API call by 2 when a lot of traces are being sent at once. This patch also fixes the hypothetical case where a trace wouldn't fit in a single Payload.
