OpenTelemetry distributed tracing platform Jaeger has become a powerful must-have observability tool for Dev and Ops teams. But Ops teams still face a big challenge in making distributed tracing practically useful. With the high volumes and complexity of trace data, how does one find the problem trace when user requests are facing slowdowns? We will introduce and demonstrate a new observability concept called TracePath that can help Ops to solve this challenge: detect problems and identify problem traces in real time using distributed tracing.
