we have renew our front end server a few month ago. The old ones have been unracked.
I wanted to compare some CPU betwenn the old and the new one but in Infrastructure I don't see the old one. Even if I create a dashlet and display CPU I don't see the old ones.
Is there any way to see history of those old servers (even if there is no agent anymore on it as thoses servers has been disconnected/unracked).
If you open a new dashboard and set the source to your Dynatrace self-monitoring system profile you should be able to chart the Frontend CPU Utilization. You could try changing the time frame of the chart to a period where you know the old servers were connected. You should then be able to compare the metrics to similar timeframe after the change was made.
Hello @David N.
I tried but if I set the source of Dynatrace self-monitoring system. I only have Dynatrace information not my front end server.
Edit 1 : Just to clarify. It's not Dynatrace front end server but application front end server (web server).
Is there any trick ?
Edit 2 : I tried to graph CPU Total Time on my current system profile and extend time to last year (where my servers were up and running but I still don't see them).
I am not aware of any tricks to get the metrics on that old web server from the client. A disconnected server is displayed on the infrastructure overview for 72 hours and beyond that time frame, I am not sure you can access the metrics.
