When limit is exceeded, a NoopScope is returned.
Allow custom ScopeManager to be provided, with the plan to remove `ScopeContext` customization in the future.
This is a more generic form of the previous `split-by-domain` and `split-by-instance`.
(Note: evaluation is done when a tag is set, so If multiple tags are configured, the last tag set will take precidence.)
For example, this setting can be used to rename `aws-sdk` spans to be identified with the corresponding `aws.service` tag:
```
-Ddd.trace.split-by-tags=aws.service
```
There are some slight differences with this setting compared with`dd.trace.http.client.split-by-domain` and `dd.trace.db.client.split-by-instance`. `split-by-tags` applies to every span, where `split-by-domain` and `split-by-instance` only apply to http and db client spans respectively.
The core changes are in Config and ServerDecorator.
Moved default tagging from Config::getRuntimeTags to Config::getLocalRootSpanTags. This changes the result of Config::getMergedJmxTags as well.
To preserve language for servers changed ServerDecorator::afterStart.
Other changes are in tests - the most complicated part is in TagsAssert::defaultTags. This now contains a bit too much conditional logic for my liking.
Expose new options for configuring JMXFetch with standard datadog-agent config files with `jvm_direct: true` set as an instance attribute (this will be ignored by the datadog-agent).
For Example:
* `dd.agent.conf.d=/opt/datadog-agent/etc/conf.d`
* `dd.jmxfetch.configs=activemq.d/conf.yaml,jmx.d/conf.yaml`
will load jmx configs in those two files that have `jvm_direct: true` in their `instance` setup.
Environment variables can also be used: `DD_AGENT_CONF_D` and `DD_JMXFETCH_CONFIGS`
Depends on https://github.com/DataDog/jmxfetch/releases/tag/0.29.0 being released.
Or all executors, bypassing the allow list.
`dd.trace.executor=com.MyCustomExecutor,com.OtherExecutor`
`dd.trace.executors.all=true`
Turns out in many cases, executors that we say we’re skipping, are still being traced because they extend from an already instrumented executor.
