I was logged into the ASDM for a Cisco ASA the other day and I wanted to view how much traffic was coming in and out of the device, but I could only view the real time data. When I clicked on any of the other available time periods, I got the  following error “ASDM history is disabled“.

The way to fix this is:

Go to the configuration tab of the ADSM.

Go down to advanced.

Click on History Metrics.

Tick the ADSM History Metrics box

Click apply

Don’t forget to save the settings to flash memory!
