0.17.4 - October 23, 2023

Return to top

Bundled OTel agent version

• Java OTel agent version 1.29.0

New features and improvements

• Custom transaction names are allowed when the trace isn't sampled.
• The value for resource.service.name is resolved to the service name defined in the service key when resource.service.name is not set.
• resource.service.name is exposed in the system properties, allowing it to be accessed by loggers and application code. The service name can be retrieved by reading the key service.name, using system property read API and from loggers using the following:
  • Log4j2: resource.service.name=${sys:service.name}
  • Logback: resource.service.name=${service.name}
• Introduces the SW_APM_SQL_TAG_PREPARED config to allow enabling trace context injection into prepared statements. SW_APM_SQL_TAG is retained to enable the same for non-prepared statements.

Fixes

• The service key does not leak via process commands and arguments.
• IMDSv2 token request no longer has a bug.
