title: Application insights | Sometimes End-to-end transaction details do not show all telemetry
body: <p>I have .Net core App deployed on azure and enabled application insights.
  Sometimes Azure application insights End-to-end transaction details do not display all telemetry.</p>
  <p>Here it only logs the error and not request or maybe request logged but both do not display together over here(difficult to find out due to many people use it)
  <a href="https://i.stack.imgur.com/BR28m.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/BR28m.png" alt="Only error log" /></a></p>
  <p>Should be like:
  <a href="https://i.stack.imgur.com/rXB6g.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/rXB6g.png" alt="Both request and error" /></a></p>
  <p>Sometimes request log but with no error log.</p>
  <p>What could be the reason for happening this? do I need to look into application insights specific set-up/feature?</p>
  <p><strong>Edit:</strong>
  As suggested by people here, try to disable the Sampling feature but still not works, <a href="https://github.com/microsoft/ApplicationInsights-dotnet/issues/1808" rel="nofollow noreferrer">Here</a> is open question as well.</p>
