Among others I am monitoring two VMs (both on a VMware ESX environment, one running openSUSE 13.2 (Harlequin), the other SUSE Linux Enterprise Server 12 SP3).
I added both to the same target group which I then added as target for performance scans. The scans are scheduled to run once per hour.
On one (the SLES 12) VM the performance scanning is working fine and - when hovering over the asset - there is a performance tab which - when selected - shows disk, memory and other figures.
On the other (the openSUSUE 13.2) VM there is no such tab shown, which - I guess - means that the performance scans are not run or don't yield any results.
Any ideas, why these performance scans are working fine on one VM but not the other? Any hints or pointers what to check or verify?
