Go Agent Release Notes
1.13.4 - August 28, 2020
- Improved OpenTracing support to add HTTP status and method tags for APM service metrics such as request throughput, latency, aggregated histograms for percentiles, and error count. This builds on the previous release which added tagging by transaction names. Service metrics and latency percentiles are aggregated across 100% of requests, not just those sampled for tracing.
- New multitracer contrib package provides the ability to use two OpenTracing tracers simultaneously. Baggage propagation is not supported.
1.13.3 - July 9, 2020
- Added support for reporting exceptions via OpenTracing span.SetTag("error", ...) calls to the AppOptics exception tracking feature.
- Use Go modules to manage dependencies.
1.13.2 - June 19, 2020
- Added support for setting transaction names via OpenTracing. This allows you to better control the names you see on the Service Transactions page and used in request metrics, latency percentiles, etc. Set the tag TransactionName or resource.name to use this feature, which is equivalent to calling the AO Go SDK's Span.SetTransactionName.
