with this change the child span of the HTTP filter span gets changed into a span coming from the Controller aspect. The name of the span becomes the name of the method.
Zipkin 1.1.1 includes a few changes relevant to sleuth:
* Adds JSON button to trace detail screen
* Presents server errors in UI
* Fixes misclassification of http span metrics (1.1.1)
https://github.com/openzipkin/zipkin-java/releases/tag/1.1.0
After this change a custom FeignContext is created that before returning instance or instances of beans will wrap, if necessary, that bean into a tracing representation. That way all the custom Feign configurations will have wrapped beans and tracing will get propagated.
Fixes#286
This moves to changes made in preparation of zipkin 1.0.
Here are the notables:
* Zipkin has autoconfiguration modules, where maven artifacts have the prefix 'zipkin-autoconfigure-X'
* Zipkin's ui now shares a version with everything else
* Zipkin now namespaces packages and configuration. ex zipkin.storage.X as opposed to zipkin.X
* All autoconfiguration classes are prefixed `Zipkin` to be easier to find
* Zipkin binds components like StorageComponent, as opposed to individual classes like SpanStore.
* Health checks are under the scope "zipkin" and broken down by component
* UI responsiveness is better by conditionally caching names queries for 5 minutes
* New `Collector` class, which makes logging and metrics patterns the same regardless of transport
Removes wiremock as a test dependency in core (which created more
issues than you might expect because Tomcat and Jetty don't treay
HTTP headers in the same way apparently).
Also moves the spring-messaging dependency to where it is needed
in sleuth stream.
This important in so far that it allows us to do metrics. The actual
implementation of stream metrics is something we can work on after 1.0
if there's a time crunch.
Notably, this removes the accidental transient dependency on scala, by
removing the dependency on `zipkin-cassandra-core`. Related classes have
been vendored into `storage-cassandra`.
This also splits out `CollectorSampler` as its own thing and introduces
two options for instrumentation sampling:
* `BoundaryTraceIdSampler` - For high-volume sites, based on Finagle
* `CountingTraceIdSampler` - Trades lower performance for high accuracy
No immediate impact to sleuth, but some notable changes underneath:
* zipkin.Sampler is now extensible to permit dynamic rate adjustments
* self-tracing can now be disabled even if Brave is in the classpath
* related property: zipkin.self-tracing.enabled
* brave-spancollector-scribe is no longer an optional dependency
In the world of plugins:
* Elasticsearch bugfix on traces w/ more than 10 spans
* New ZooKeeper adaptive collection-tier sampler
This updates to the latest release. Beyond bug fixes, there are some
notable changes:
* storage: writes are now via AsyncSpanConsumer
* storage: added elasticsearch
* zipkin-ui: constrains start time to look for traces
* zipkin-ui: assets set cache headers, increasing responsiveness
* core: debug logging available for zipkin.internal.DependencyLinker
Notably, this removes the "zipkin-web" dependency, as the UI is now
collocated on zipkin-server.
Other notable changes are Cassandra and Kafka support, as well removing
the Brave dependency.
This is a maintenance update to zipkin which has no api impact.
* zipkin-server supports cassandra now
* zipkin-web is now javascript (even if still hosted on a scala process)
