View an x-ray session

After you start a New Relic APM x-ray session ( or > Key transactions > (select a key transaction) > x-ray), New Relic will collect up to 100 transaction traces and a thread profile for your key transaction. Collection automatically stops based on the options you select.

Access to this feature depends on your subscription level.

Every ten seconds the x-ray sessions index refreshes automatically. The x-ray sessions index (newest to oldest) shows:

  • X-ray session name
  • Current progress
  • Number of traces
  • Author (email link for the person who created the x-ray session)
  • When the session started
  • Current status (Starting, Running, Stopped, Finished)
  • Icons to edit (rename), stop (cancel), or delete the x-ray session

From the x-ray session index, select any row to view page details.
