we use LMS 4.2.1 and we noticed a strange behaviour when starting a discovery. From aprox. 160 devices some devices are displayed as IP Address instead of hostname. Every device is DNS resolvable and has a value for "hostname"
I´ve tried every possible option in the global discovery settings but some devices have the IP instead of their hostname
Can you tell me how to fix this? Thank you.
DNS is often not understood and just as often implemented badly
When it is working correct you can do 2 things:
will start ping towards the IP address of the host.
will resolve the ip to a hostname if possibe and then start a ping towards the IP address.
Often only the first works. Reverse lookup is required by LMS as well.
if you can fix the DNS you can always create a local hosts file
