We have a vlan configured for scanning the assets.Which scans all the availble assets in the vlan. however, we see only few assets are getting scanned completely and few assets last scan date remains as 1 or 2 months ago. Same firewall policy has been applied for all the assets. Troubleshooted in firewall and traffic between insightvm to assets getting allowed.
when you look at the asset page, down the page there is a scan asset history section.. are there different IP’s being scanned on that host at different times?
IF no, then are you confirming that the hosts that are expected to be there are reachable, have you attempted to scan them indapendately one at a time to see if there being picked up as part of your troubleshooting?
