(Jaeger)[https://www.jaegertracing.io/] is an open source, end-to-end distributed tracing solution. It is a part of the Cloud Native Computing Foundation (CNCF)[https://www.cncf.io/].
The (jaeger-collector)[https://www.jaegertracing.io/docs/1.7/deployment/#collectors] is part of the Jaeger deployment architecture that receives spans from agents/instrumented tasks and writes them out to the chosen storage backend.
It is possible to deploy jaeger-collector in a kubernetes environment, for example through steps described (here)[https://github.com/jaegertracing/jaeger-kubernetes].
This dashboard helps you monitor the health of a jaeger-collector component that is running in a kubernetes environment.
