In opentelemetry, there is something called as span
and trace
.
-
Basically think of one http request. The whole lifetime of request and response can be called
trace
. And things done along the way is calledspan
. Lets say when request comes, and we want to create some file or read something for that request that will be onespan
. And so on. That is how we know the whole lifetime of request. -
Now when we collect the data we might want to send it to external system to display for that we want what we call as
exporters
.
