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, two parameters should be changed in the newrelic.ini file:newrelic.distributed_tracing_enabled = true
andnewrelic.transaction_tracer.threshold = 0
- A bug in the PHP agent resulted in databaseCallCount attributes no longer being attached to Transaction events. The 8.4 release restores these attributes.
- Predis 2 cluster connections could not be instrumented due to internal changes in Predis. The 8.4 release fixes this.
