Node.js agent release notesRSS

• Added a check for invalid characters in the app_name setting.

  The agent will now emit a warning and disable itself if any application name is invalid. Allowed characters are alphanumerics and certain punctuation characters ({}.?!')

• Router queue time now properly handles floating point values.

• Fixed a bug where a socket connection could throw a synchronous error and cause the application to crash.

• We now support Cassandra via the node-cassandra-cql driver.

  New database instrumentation means that we can present you with the timing data for how long those queries take. Thanks to Aaron Silvas from GoDaddy for the initial implementation of the Cassandra instrumentation.

• Router queue time now supports t=<number> in the X-REQUEST-START and X-QUEUE-START headers.

Notes

• Agent now tracks metrics for router queue time. In addition to X-REQUEST-START, the agent now supports X-QUEUE-START header times. This metric will show up as "Request Queueing" in the Overview tab.

Notes

• General release of proxy support for the agent to connect to New Relic.
  • HTTP/HTTPS support from the newrelic module to the proxy
  • HTTP/HTTPS support from the newrelic module to New Relic.
  • Basic proxy authentication.
  • Allow custom certificates during TLS negotiation.
  • For more information, read our docs here
• Fix for enabling High-security mode via an environment variable
• Optimization to allow early garbage collection of TLS slab buffers.

Notes

• Plain http routes (i.e. routes outside of a framework) now apply config naming rules early. See rules for naming and ignoring requests.

  This fixes a bug where generating the Browser Timing Header would not work without a framework (i.e. express, restify, hapi).

• Beta support for connecting to newrelic via ssl through a proxy.

Notes

• The agent now reports the value of the NODE_ENV environment variable to New Relic.

  This will show up in your Settings -> Environment tab in APM. The data is being collected for debugging and to aid support.

Notes

• Support for instrumenting a standalone express 4 router. See issue 154.
• Set the default log level to info.

Notes

• Captured parameters for express, restify, and hapi have been normalized.

  When capture_params is enabled the agent will collect route and query parameters. Previously express and restify only captured route params, and hapi only captured query params. This normalizes the behavior across the frameworks.

• Fixed an issue with restify instrumentation that caused the agent to always collect route parameters.

  Users of restify who want to continue capturing route (and now query) parameters are advised to enable capture_params.

• Fixed an issue where circular configs caused the agent to crash.

Notes

• Fixed an issue where collected errors did not include captured and custom parameters.
• Added the environment variable NEW_RELIC_HIGH_SECURITY. This correlates to the high_security setting in your newrelic.js for High-security mode.
