Stackdriver Trace is a distributed tracing system that collects latency data from applications, Google App Engine, and HTTP(s) load balancers, and displays it in near-real time in the GCP console. For applications to be able to use this feature, they need to have the appropriate code in place with the Stackdriver Trace SDKs, but this is not needed if your application is being deployed in Google App Engine. Stackdriver Trace greatly enhances your understanding of how your application behaves. Things like time to handle requests and complete RPC calls can be viewed in real time using Stackdriver Trace:
Some use cases for Stackdriver Trace include the following:
- Reviewing historical latency data
- Reviewing detailed latency data, including performance insights and RPC calls
- Generating custom reports for latency data, and building comparison models for latency data...
