My router is a Linux server, so I think netdisco did not discover it.
Is it necessary in order to get the Ip's of the devices connected to it?
Thanks.

Have you discovered the router with Netdisco for the subnets that your
hosts are on?

Yes, netdisco has to ask routeurs to get ARP information (MAC/IP
associations).
Have a nice day,

You should run the snmp agent (snmpd) on your Linux server, and
configure it according to this:
https://metacpan.org/pod/distribution/App-Netdisco/lib/App/Netdisco/Manual/Vendors.pod#Linux-SNMP-Service-(Agent)
Is it necessary in order to get the Ip's of the devices connected to

Yes. MAC addresses come from the switches, IP addresses come from your
router.

Alright, I see. I am gonna try it,
Do you guys think those services could overload my router or cause
service degradation?
Thanks.

Have you discovered the router with Netdisco for the subnets that your
hosts are on?
