We have refreshed the access logs , But the response time is not displayed.
Are you sure you have created HTTP transactions for the relevant managed server? Remember you need to create real traffic to exceed 8kb buffer size for the response times monitoring. So, at least there must be +100 request after managed server restart.
Are you sure you have selected the right managed server on the “Response Times” page? (Please take below screen capture as a reference)
