I can't use Netsight OneView dashboard for watching device up/down. It seems that it never refreshes or refreshes too late. Cacti shows device down in about 1 minutes. Even after 5-10 mins Oneview dashboard does not update and show the device is down. But if I manually refresh the browser it shows device down. Also Oneview devices tab shows down devices in 1 minute. So it seems the problem is dashboard is not refreshed. I look for but could not find any setting for dashboard refresh interval.
