Our client experience that the dashboard with timeframe of 1 hour will show missing data as shown below:
The dashlet only showing 2 hosts CPU usage while the other 6 hosts are missing. After refresh it would still missing. However, it would appear if click on previous 1 hour and comeback to latest 1 hour. Nevertheless, it also happen when the timeframe is set to 30min:
The graph will show CPU usage of 2 hosts only while the other 6 hosts are missing. It only happen for this application.
It is impacting their daily operation as they cannot see the latest monitoring data and suspected it went offline. Else they have to keep go to previous 1 hour and comeback to last 1 hour.
i have double check on the infrastructure overview. There are data as shown in image below:
Due to some reason, our client are still using the AppMon version 7.0.25 and it is EOL. Please help.

Hello, the question is if agent on those hosts are able to send data to collector live. Arent network intefaces exhausted there? Did you check agent and collector logs?
If you have those data on host tab, but not on dashboard it may be issue. In general you can upgrade appmon server without upgrading agents so it can be done. In general I suggest checking collector health, server health, server logs and if there is no interesting entries, open support ticket.
