Node.js agent release notesRSS

New Features

• Added CPU metric gathering to Node.js versions <6.1

  As of this release the agent will attempt to gather CPU usage metrics via the optional @newrelic/native-metrics module.

• Added additional memory usage classification metrics.

  The agent will now report memory metrics that break down memory by its current use.

  For more information on these features, see our documentation.

Bug fixes

• Removed automatic installation of @newrelic/native-metrics.

  Due to the way npm v3+ flatten dependencies, a bug in the version of npm packaged with Node v5, and npm v1's ungraceful handling of scoped packages we have opted to not automatically install this module.

  If you would like to see native metrics for your application, you can add the @newrelic/native-metrics module to your package.json and the Node Agent will automatically pick it up.

• Corrected attribution of the Bluebird patch in the last release's notes.

  Thanks to Matt Lavin (@mdlavin) for this correction!

Notes

New features

• The agent will now report garbage collection statistics on supported platforms.

  On node versions 0.10, 0.12, 4, 6, and 7 the agent will now record the time spent in, the number of, and type of garbage collection cycles. You can read more about it on our docs site!

Bug fixes

• The agent no longer double counts MySQL query times when using a connection pool.

  Previously, when using a pool of connections a query done through the pool would be recorded as the time it took on the pool, as well as the connection, effectively counting the time twice. This is no longer the case.

• The agent will no longer lose transaction state across Bluebird's promise.nodify.

  Thanks to Matt Lavin (@mdlavin) for this contribution!

New features

• The agent now collects CPU metrics when running under Node 6.1.0 and higher.

  Node 6.1.0 introduced an API to get CPU time usage of the running Node process. We are now collecting this data as new metrics.

• The agent now has a separate configuration for audit logging.

  Previously the data that the agent sends to the collector was logged only in trace logging mode, making the logs unnecessarily large and noisy. The agent can now include this data independent of the logging level using separate configuration settings.

• A new API method addCustomParameters() has been added to allow adding multiple custom parameters at once. Thanks to Austin Peterson (@AKPWebDesign) for this contribution!

Improvements

• Updated tests to run on Node 7.

  Node 7 is officially supported as of the previous release, v1.33.0.

• The shutdown() API now waits for connection to collect pending data.

  When a flag to collect pending data is provided to the shutdown() method, the agent now ensures a connection to the collector has been established. This is useful when the Node process is short-lived, such as in AWS Lambda.

• Added running the nsp (Node Security Platform) tool to the test suite to help with detecting security-related vulnerabilities.

Bug fixes

• The setIgnoreTransaction() API now works for background transactions.
• Fixed issue with synthetic result not displaying a link to the corresponding transaction trace.

Improvements

• Incorporated new features and fixes from v1.30.4, v1.30.5, v1.31.0, v1.32.0, and v1.33.0.

New features

• The agent now collects database instance information for Memcached operations.

  This information (database server and database name) is displayed in transaction traces and slow query traces.

Improvements

• socket.io long-polling requests are now ignored by default.

  Collecting metrics for these requests is typically not desirable since they are frequent and do not represent business transactions. Previously we recommended adding an ignore rule manually. Now it is included by default.

• Improved test coverage for Postgres and MongoDB instrumentations.

New features

• The agent now collects database instance information for MySQL and MongoDB operations. This information (database server and database name) is displayed in transaction traces and slow query traces.
• Datastore instance configuration can now be done through environment variables. These can be set through NEW_RELIC_DATASTORE_INSTANCE_REPORTING_ENABLED and NEW_RELIC_DATASTORE_DATABASE_NAME_REPORTING_ENABLED

Bug fixes

• The agent will no longer crash the process when an express param handler is executed when a transaction is not active.

New features

• The agent now collects database instance information for PostgreSQL and Redis operations. This information (database server and database name) is displayed in transaction traces and slow query traces.

Bug fixes

• Fixed issue with aborted requests causing the agent to crash in some cases.

  Previously the agent would crash when the client request aborted before Express server sent a response and encountered an error.

Improvements

• Upgraded integration tests to work with the latest version of node-tap.
