0.30.0

Improvements

• Provide configuration properties to add tags for query string and query fragments in http server and client spans:
  • Server:
    • System Property: dd.http.server.tag.query-string=true
    • Environment Variable: DD_HTTP_SERVER_TAG_QUERY_STRING=true
  • Client:
    • System Property: dd.http.client.tag.query-string=true
    • Environment Variable: DD_HTTP_CLIENT_TAG_QUERY_STRING=true
• Set the service name for db clients spans as the instance name of the database when the configuration property -Ddd.trace.db.client.split-by-instance=true or env DD_TRACE_DB_CLIENT_SPLIT_BY_INSTANCE=true is activated #881
• Improve our process to parse db instance name out of jdbc connection string for a number of different vendors #866
• Added option to configure the tracer via properties file. The file path can be provided via -Dtrace.config=/path/to/file.properties or env DD_TRACE_CONFIG=/path/to/file.properties #862
• Tests Java 12 in our CI environment #868

Changes

• Update Mongo instance name and remove memcache instance name #880
• Deprecated static methods in Config.java class previously used to statically retrieve configuration properties. The new pattern is now to access all the properties via instance methods on the configuration singleton accessible through Config.get() #863

0.29.1

Changes

• Reverted breaking changes to Kafka and RabbitMQ service names introduced in 0.29.0 #861

0.29.0

Improvements

• Upgrade JMXFetch to 0.29.0 and enable JMXFetch by default. #838

  • To disable it add the one of the following config:
    • System Property: dd.jmxfetch.enabled=false
    • Environment Variable: DD_JMXFETCH_ENABLED=false

• Bundled jmx integrations must now be configured via (default still disabled):

  • System Property dd.jmxfetch.<integration>.enabled=true
  • Environment Variable DD_JMXFETCH_<INTEGRATION>_ENABLED=true

• New config options are passed through that enable datadog-agent config files to be used for JMXFetch. For example, the following will load jmx configs in those two files that have jvm_direct: true in their instance setup:

  • dd.jmxfetch.config.dir=/opt/datadog-agent/etc/conf.d
  • dd.jmxfetch.config=activemq.d/conf.yaml,jmx.d/conf.yaml
  • Environment variables can also be used: DD_JMXFETCH_CONFIG_DIR and DD_JMXFETCH_CONFIG

• JMXFetch now uses the same logging system as dd-java-agent. This will help reduce logging noise when using JMXFetch.

• Allow async propagation by default within Spring Controllers #856

Fixes

• Prevent Glassfish's classloader from blacklisting classes added to the bootstrap by the agent #839
• Improve Kafka instrumentation scope handling #859
• Avoid setting Kafka headers when connected to an old/incompatible broker #836
• Use default service name for Kafka Consumers #854 (Reverted in #861 -- 0.29.1)
• Use default service name for RabbitMQ Consumers #855 (Reverted in #861 -- 0.29.1)

For a full list of changes please reference the milestone for this release.

  • dd.trace.executors=com.MyCustomExecutor,com.OtherExecutor
  • dd.trace.executors.all=true
  • Environment Variables: DD_TRACE_EXECUTORS, DD_TRACE_EXECUTORS_ALL

0.26.2

Bug Fix

This is a critical release fixing a bug introduced in 0.26.0. Please upgrade to this instead of using 0.26.0 or 0.26.1.

• Report correct content length when sending traces to the agent. #783

0.26.1

WARNING:

This release has a bug calculating the content length for tracer payloads with more than 15 traces (per second). This miscalculation causes the agent to drop the payload. This is fixed in 0.26.2.

Bugs

• Fix regression introduced in version 0.26.0 where it was impossible to instantiate HttpsURLConnectionImpl due to missing classes. #781
• Fix config key for http status error mapping. The following config should now work properly. #782
  • System Property:
    • dd.http.client.error.statuses=400-499
    • dd.http.server.error.statuses=500-599
  • Environment Variable:
    • DD_HTTP_CLIENT_ERROR_STATUSES=400-499
    • DD_HTTP_SERVER_ERROR_STATUSES=500-599
