without this change it's pretty much impossible to enforce sampling for certain traces
with this change setting the X-B3-Flags to 1 for HTTP messages / spanFlags to 1 for messaging will override any sampling decisions
fixes#496
Local Ip determined from spring.commons InetUtils.
To enable local endpoint resolution via service discovery, DiscoveryClient must be present and 'spring.zipkin.service.locator.discovery' should be set to true.
FallbackHavingEndpointLocator was caching and recreating EndpointLocator in the same time - removed the caching part.
Fixes gh-403
without this only either service discovery service id / spring.application.name can be chosen as a service name for zipkin
with this change you can pass spring.zipkin.service.name property to change override that both for HTTP and Stream collectors
fixes#324
without this change there is no support for context propagation
with this change whenever you pass the `baggage-...` for http or `baggage_` for messaging headers then such a value will be propagated through your system
fixes#237
without this change the percentage value might have been set to over 1.0
with this change we explain what are the valid values and what are the reasons for keeping the value as it is
fixes#397
without this change it could be nonclear where Tracer comes from and how you can use it.
With this change hopefully it get properly explained
fixes#402
we had a couple of questions related to missing attributes in the logback file or the logs as such. It's related to the fact that once you provide a custom logback file you have to place the propery of spring.application.name in the bootstrap file
fixes#376
What we're missing ATM is different documentation versions for different application versions. What this change does is that it's:
- finding out what is the current branch (e.g. 1.0.x)
- finding out out what is the name of the main adoc file (e.g. spring-cloud-sleuth)
- pulling the changes from gh-pages after checkout
- finding out what is the list of comma separated whitelisted branches (via the `docs.whitelisted.branches` prop)
- in gh-pages creating a folder with name of the branch (e.g. /1.0.x)
copying all the docs/target/generated-docs/ to that folder
- if the branch from which we're calling the script is NOT master then we're changing the ${main.adoc}.html to index.html so that it's easier to access the docs (e.g. http://cloud.spring.io/spring-cloud-sleuth/1.0.x/)
Using the e.g properties from Zipkin Consumer gives the following error when loading the zipkin-server ui:
ERROR: cannot load service names: zipkin/storage/mysql/internal/generated/tables/ZipkinAnnotations
ERROR: cannot load span names: zipkin/storage/mysql/internal/generated/tables/ZipkinSpans
So to fix it you have to explicitly add username and password for the mysql storage.
* Fix headers in messaging
with this change the span related headers are changed to be compatible with messaging specs. The change is backwards compatible so we accept the old ones as input, and as output we're producing both new and old headers.
fixes#332
