- Converted File System instrumentation to use newer shim style.
- Converted DNS instrumentation to newer shim style.
- Added tracking of callbacks to DNS instrumentation.
- Converted crypto instrumentation to newer shim style.
- Updated domains instrumentation to use an instrumentation shim.
- Refactored the global instrumentation to use the shim API.
- Ported inspector instrumentation to use an instrumentation shim.
- Ported async_hooks based promise instrumentation over to using shims.
- Added shim types for core instrumentations.
- Improved benchmark comparison output.
Agent instrumentation will no longer interfere with promisification of core methods.
Some core methods expose pre-promisified versions of the methods as a reference on the method itself. When instrumenting these methods, it neglected to forward these references onto the wrapper function. Now the instrumentation will properly forward property look ups to the original method.
Fixed outbound https call to use example.com to resolve integration test issue.
Fixed tests for ioredis 4.0.0 and above.
Implemented enforcement of
Any payload during the harvest sequence that exceeds the configured limit will be discarded.
Added JSON-formatted output to benchmarks to enable automated benchmark comparison.
Updated the benchmark runner to measure specifically userland CPU overhead.
Added DatastoreShim benchmarks.
Fixed MongoDB instrumentation for driver versions greater than 3.0.6.
Mongo 3.0.6 removed metadata the Agent relied upon to instrument the driver. This fixes that by going back to the old method of manually listing all objects and methods to instrument.
Updated MySQL versioned tests to run against the latest release.
Added support for distributed tracing.
Distributed tracing lets you see the path that a request takes as it travels through your distributed system. By showing the distributed activity through a unified view, you can troubleshoot and understand a complex system better than ever before.
Distributed tracing is available with an APM Pro or equivalent subscription. To see a complete distributed trace, you need to enable the feature on a set of neighboring services. Enabling distributed tracing changes the behavior of some New Relic features, so carefully consult the transition guide before you enable this feature.
To enable distributed tracing, set
newrelic.jsfile, or set
NEW_RELIC_DISTRIBUTED_TRACING_ENABLEDin your environment.
Added a warning for too-new versions of Node.js during agent startup.
Appropriately obfuscated SQL statements will now be included in all transaction traces.
Previously, the agent would only include the SQL statements if the corresponding query was sufficiently slow.
Added ability to execute instrumentation functions in the context of the segment the segment descriptor is describing.
record*methods supplied by all instrumentation shim classes now allow for a function to be executed under the context of the segment the record call will produce. This may be done by supplying a function in the
inContextkey for the segment descriptor passed to the record method.
Reservoirs will now respect setting their size to 0.
Feature flags may now be set from environment variables.
Using the naming convention
NEW_RELIC_FEATURE_FLAG_<feature flag name in upper case>.
Transaction events may be harvested in two payloads now.
This change reduces the occurrence of harvests being rejected due to large payloads. Payloads will only be split when they are large (greater than 1/3 the maximum).
- Updated Hapi v17 instrumentation to wrap
serverexport, in addition to
- Added node v10 to the test matrix.
utilizationenv vars to the
This ensures that if these boolean config values are set outside of a config file, their values are respected, particularly when they are disabled.
This allows people to pass in a string to be injected as the
nonceproperty of the generated script tag. Special thanks to João Vieira (@joaovieira) for contributing this feature!
Expose the External segment on the
httprequest instance for outbound calls.
Added check to mark Hapi
'onPreResponse'extensions as error handlers.
Previously, the agent was unable to mark any Hapi errors as handled, even if they were, resulting in inaccurate reporting. This change assumes that
'onPreResponse'extensions act as error handlers, so errors are only reported if they persist to the final response.
- Added more tests for transaction naming with Restify.
Fixed issue with tracking external requests to default ports.
Special thanks to Ryan King for pinpointing the cause of this issue.
Added extra check for handling arrays of functions when wrapping middleware mounters.
This fixes a bug with the agent incorrectly assuming that arrays passed as the first argument in middleware would only contain route paths, causing a fatal error.
The agent now reports the total time of the transaction on transaction events.
Added an option for using the
finallymethod on promises for instrumentation.
The promise instrumentation would use
Promise#finallyif available. This change is in response to Node v10 promises calling
finallymethod, which caused infinite recursion in the agent's promise instrumentation.
Added seen/sent/dropped supportability metrics for all event collections.
Refactored harvest cycle into separate class.
This refactoring eases managing harvested data and re-merging unharvested values on failure.
No longer download gcc on test suites that do not require it.
WebFrameworkShimto handle arrays of routes when wrapping middleware mounters.
Previously, a transaction that hit a shared middleware (eg,
app.use(['/one', '/two'], ...)) would always be tagged with
<unknown>in its name, due to the agent not interpreting arrays of paths. Now transaction names will include all paths for a shared middleware, comma-delimited, followed by the current route (
