When a target is unwatched on SQLSentry, it does not show the collected data, it requires watching. However, watching means activating data collection and it should be able to show the old data that has already been collected without any problems when there is no such need.
This situation is mostly impossible when you want to compare the collected data of your old offline server after migrating to a new server.
In addition to this; I was alwayson examining a server at the time of the problem and there was data for 09:00 and I detected the problem with disk waits, disk latency values. Then I did a failover process and unwatched the server whose data I examined and restarted it. Later, when I wanted to see this collected data again to prepare the problem analysis report, it started showing as no data exists. I watched the server but it still did not show the data I had seen before. I think this is a serious problem and should be fixed. Also, there should not be a requirement to watch.
