From 468930273b4c95f5b748f037f0285757e21df7ee Mon Sep 17 00:00:00 2001 From: Marcin Grzejszczak Date: Wed, 3 Jan 2018 17:06:26 +0100 Subject: [PATCH 01/38] Initial work with Brave What's done? - Web Server - Simple handler interceptor - Web Clients - RestTemplate - Slf4j - with Brave in place it will also work for any other implementation (e.g. log4j) In progress TraceCallable and TraceRunnable in order to then do stuff with asyncs and then eventually callable on mvc to make the next samples pass. --- .../app/SleuthBenchmarkingSpringApp.java | 11 +- spring-cloud-sleuth-core/pom.xml | 18 +++

    Overhead of adding Trace Data

    + * + * Overhead is directly related to the size of trace data exported out of process. + * Accordingly, it is better to tag what's important for latency troubleshooting, i.e. a + * whitelist vs. collecting everything and filtering downstream. The keys listed here are + * very common in tracing tools, and are considerate to the issue of overhead. + * + *

    + * When evaluating new keys, consider how much additional data it implies, and if that + * data is critical to classifying, filtering or displaying traces. More data often means + * larger systems, less retention, or a lower sample rate. + * + *

    + * For example, in zipkin, a thrift-encoded span with an "sr" annotation is 82 bytes plus + * the size of its name and associated service. The maximum size of an HTTP cookie is 4096 + * bytes, roughly 50x that. Even if compression helps, if you aren't analyzing based on + * cookies, storing them displaces resources that could be used for more traces. + * Meanwhile, you have another system storing private data! The takeaway isn't never store + * cookies, as there are valid cases for this.

    Overhead of adding Trace Data

    - * - * Overhead is directly related to the size of trace data exported out of process. - * Accordingly, it is better to tag what's important for latency troubleshooting, i.e. a - * whitelist vs. collecting everything and filtering downstream. The keys listed here are - * very common in tracing tools, and are considerate to the issue of overhead. - * - *

    - * When evaluating new keys, consider how much additional data it implies, and if that - * data is critical to classifying, filtering or displaying traces. More data often means - * larger systems, less retention, or a lower sample rate. - * - *

    - * For example, in zipkin, a thrift-encoded span with an "sr" annotation is 82 bytes plus - * the size of its name and associated service. The maximum size of an HTTP cookie is 4096 - * bytes, roughly 50x that. Even if compression helps, if you aren't analyzing based on - * cookies, storing them displaces resources that could be used for more traces. - * Meanwhile, you have another system storing private data!

Spring Cloud Sleuth has a -`Sampler` strategy that you can implement to take control of the -sampling algorithm. Samplers do not stop span (correlation) ids from -being generated, but they do prevent the tags and events being -attached and exported. By default you get a strategy that continues to -trace if a span is already active, but new ones are always marked as -non-exportable. If all your apps run with this sampler you will see -traces in logs, but not in any remote store. For testing the default -is often enough, and it probably is all you need if you are only using -the logs (e.g. with an ELK aggregator). If you are exporting span data -to Zipkin, there is also an `AlwaysSampler` +Sampling may be employed to reduce the data collected and reported out +of process. When a span isn't sampled, it adds no overhead (noop). + +Sampling is an up-front decision, meaning that the decision to report +data is made at the first operation in a trace, and that decision is +propagated downstream. + +By default, there's a global sampler that applies a single rate to all +traced operations. `Tracer.Builder.sampler` is how you indicate this, +and it defaults to trace every request. + +=== Declarative sampling + +Some need to sample based on the type or annotations of a java method. + +Most users will use a framework interceptor which automates this sort of +policy. Here's how they might work internally. + +```java +// derives a sample rate from an annotation on a java method +DeclarativeSampler sampler = DeclarativeSampler.create(Traced::sampleRate); + +@Around("@annotation(traced)") +public Object traceThing(ProceedingJoinPoint pjp, Traced traced) throws Throwable { + Span span = tracing.tracer().newTrace(sampler.sample(traced))... + try { + return pjp.proceed(); + } finally { + span.finish(); + } +} +``` + +=== Custom sampling + +You may want to apply different policies depending on what the operation +is. For example, you might not want to trace requests to static resources +such as images, or you might want to trace all requests to a new api. + +Most users will use a framework interceptor which automates this sort of +policy. Here's how they might work internally. + +```java +Span newTrace(Request input) { + SamplingFlags flags = SamplingFlags.NONE; + if (input.url().startsWith("/experimental")) { + flags = SamplingFlags.SAMPLED; + } else if (input.url().startsWith("/static")) { + flags = SamplingFlags.NOT_SAMPLED; + } + return tracer.newTrace(flags); +} +``` + +Note: the above is the basis for the built-in https://github.com/openzipkin/sleuth/tree/master/instrumentation/http[http sampler] + +=== Sampling in Spring Cloud Sleuth + +Spring Cloud Sleuth by default sets all spans to non-exportable. +That means that you will see traces in logs, but not in any remote store. +For testing the default is often enough, and it probably is all you need +if you are only using the logs (e.g. with an ELK aggregator).

The most common propagation +approach is to copy a trace context from a client sending an RPC request +to a server receiving it. + +For example, when an downstream Http call is made, its trace context is +sent along with it, encoded as request headers: + +``` + Client Span Server Span +┌──────────────────┐ ┌──────────────────┐ +│ │ │ │ +│ TraceContext │ Http Request Headers │ TraceContext │ +│ ┌──────────────┐ │ ┌───────────────────┐ │ ┌──────────────┐ │ +│ │ TraceId │ │ │ X─B3─TraceId │ │ │ TraceId │ │ +│ │ │ │ │ │ │ │ │ │ +│ │ ParentSpanId │ │ Extract │ X─B3─ParentSpanId │ Inject │ │ ParentSpanId │ │ +│ │ ├─┼─────────>│ ├────────┼>│ │ │ +│ │ SpanId │ │ │ X─B3─SpanId │ │ │ SpanId │ │ +│ │ │ │ │ │ │ │ │ │ +│ │ Sampled │ │ │ X─B3─Sampled │ │ │ Sampled │ │ +│ └──────────────┘ │ └───────────────────┘ │ └──────────────┘ │ +│ │ │ │ +└──────────────────┘ └──────────────────┘ +``` + +The names above are from [B3 Propagation](https://github.com/openzipkin/b3-propagation), +which is built-in to Brave and has implementations in many languages and +frameworks. + +Most users will use a framework interceptor which automates propagation. +Here's how they might work internally. + +Here's what client-side propagation might look like + +```java +// configure a function that injects a trace context into a request +injector = tracing.propagation().injector(Request.Builder::addHeader); + +// before a request is sent, add the current span's context to it +injector.inject(span.context(), request); +``` + +Here's what server-side propagation might look like + +```java +// configure a function that extracts the trace context from a request +extracted = tracing.propagation().extractor(Request::getHeader); + +// when a server receives a request, it joins or starts a new trace +span = tracer.nextSpan(extracted, request); +``` + +=== Propagating extra fields + +Sometimes you need to propagate extra fields, such as a request ID or an alternate trace context. +For example, if you are in a Cloud Foundry environment, you might want to pass the request ID: + +```java +// when you initialize the builder, define the extra field you want to propagate +tracingBuilder.propagationFactory( + ExtraFieldPropagation.newFactory(B3Propagation.FACTORY, "x-vcap-request-id") +); + +// later, you can tag that request ID or use it in log correlation +requestId = ExtraFieldPropagation.get("x-vcap-request-id"); +``` + +You may also need to propagate a trace context you aren't using. For example, you may be in an +Amazon Web Services environment, but not reporting data to X-Ray. To ensure X-Ray can co-exist +correctly, pass-through its tracing header like so. + +```java +tracingBuilder.propagationFactory( + ExtraFieldPropagation.newFactory(B3Propagation.FACTORY, "x-amzn-trace-id") +); +``` + +==== Prefixed fields + +You can also prefix fields, if they follow a common pattern. For example, the following will +propagate the field "x-vcap-request-id" as-is, but send the fields "country-code" and "user-id" +on the wire as "x-baggage-country-code" and "x-baggage-user-id" respectively. + +Setup your tracing instance with allowed fields: + +```java +tracingBuilder.propagationFactory( + ExtraFieldPropagation.newFactoryBuilder(B3Propagation.FACTORY) + .addField("x-vcap-request-id") + .addPrefixedFields("baggage-", Arrays.asList("country-code", "user-id")) + .build() +); +``` + +Later, you can call below to affect the country code of the current trace context + +```java +ExtraFieldPropagation.set("country-code", "FO"); +String countryCode = ExtraFieldPropagation.get("country-code"); +``` + +Or, if you have a reference to a trace context, use it explicitly + +```java +ExtraFieldPropagation.set(span.context(), "country-code", "FO"); +String countryCode = ExtraFieldPropagation.get(span.context(), "country-code"); +``` + +IMPORTANT: In comparison to previous versions of Sleuth, with +Brave it's required to pass the list of whitelisted baggage keys +via the `spring.sleuth.baggage-keys` property. + +==== Extracting a propagated context + +The `TraceContext.Extractor` reads trace identifiers and sampling status +from an incoming request or message. The carrier is usually a request object +or headers. + +This utility is used in standard instrumentation like [HttpServerHandler](../instrumentation/http/src/main/java/sleuth/http/HttpServerHandler.java), +but can also be used for custom RPC or messaging code. + +`TraceContextOrSamplingFlags` is usually only used with `Tracer.nextSpan(extracted)`, unless you are +sharing span IDs between a client and a server. + +==== Sharing span IDs between client and server + +A normal instrumentation pattern is creating a span representing the server +side of an RPC. `Extractor.extract` might return a complete trace context when +applied to an incoming client request. `Tracer.joinSpan` attempts to continue +the this trace, using the same span ID if supported, or creating a child span +if not. When span ID is shared, data reported includes a flag saying so. + +Here's an example of B3 propagation: + +``` + ┌───────────────────┐ ┌───────────────────┐ + Incoming Headers │ TraceContext │ │ TraceContext │ +┌───────────────────┐(extract)│ ┌───────────────┐ │(join)│ ┌───────────────┐ │ +│ X─B3-TraceId │─────────┼─┼> TraceId │ │──────┼─┼> TraceId │ │ +│ │ │ │ │ │ │ │ │ │ +│ X─B3-ParentSpanId │─────────┼─┼> ParentSpanId │ │──────┼─┼> ParentSpanId │ │ +│ │ │ │ │ │ │ │ │ │ +│ X─B3-SpanId │─────────┼─┼> SpanId │ │──────┼─┼> SpanId │ │ +└───────────────────┘ │ │ │ │ │ │ │ │ + │ │ │ │ │ │ Shared: true │ │ + │ └───────────────┘ │ │ └───────────────┘ │ + └───────────────────┘ └───────────────────┘ +``` + +Some propagation systems only forward the parent span ID, detected when +`Propagation.Factory.supportsJoin() == false`. In this case, a new span ID is +always provisioned and the incoming context determines the parent ID. + +Here's an example of AWS propagation: +``` + ┌───────────────────┐ ┌───────────────────┐ + x-amzn-trace-id │ TraceContext │ │ TraceContext │ +┌───────────────────┐(extract)│ ┌───────────────┐ │(join)│ ┌───────────────┐ │ +│ Root │─────────┼─┼> TraceId │ │──────┼─┼> TraceId │ │ +│ │ │ │ │ │ │ │ │ │ +│ Parent │─────────┼─┼> SpanId │ │──────┼─┼> ParentSpanId │ │ +└───────────────────┘ │ └───────────────┘ │ │ │ │ │ + └───────────────────┘ │ │ SpanId: New │ │ + │ └───────────────┘ │ + └───────────────────┘ +``` + +Note: Some span reporters do not support sharing span IDs. For example, if you +set `Tracing.Builder.spanReporter(amazonXrayOrGoogleStackdrive)`, disable join +via `Tracing.Builder.supportsJoin(false)`. This will force a new child span on +`Tracer.joinSpan()`. + +==== Implementing Propagation + +`TraceContext.Extractor` is implemented by a `Propagation.Factory` plugin. Internally, this code +will create the union type `TraceContextOrSamplingFlags` with one of the following: +* `TraceContext` if trace and span IDs were present. +* `TraceIdContext` if a trace ID was present, but not span IDs. +* `SamplingFlags` if no identifiers were present + +Some `Propagation` implementations carry extra data from point of extraction (ex reading incoming +headers) to injection (ex writing outgoing headers). For example, it might carry a request ID. When +implementations have extra data, here's how they handle it. +* If a `TraceContext` was extracted, add the extra data as `TraceContext.extra()` +* Otherwise, add it as `TraceContextOrSamplingFlags.extra()`, which `Tracer.nextSpan` handles. + +== Current Tracing Component + +Brave supports a "current tracing component" concept which should only +be used when you have no other means to get a reference. This was made +for JDBC connections, as they often initialize prior to the tracing +component. + +The most recent tracing component instantiated is available via +`Tracing.current()`. You there's also a shortcut to get only the tracer +via `Tracing.currentTracer()`. If you use either of these methods, do +noot cache the result.
