What is agentDhcpServerNAKMessagesSent?
This read-only counter counts DHCPNAK messages sent by the server, which reject a client's lease request (for example because the requested address is no longer valid or available). A sudden spike often means clients are trying to reuse addresses from a pool that has since been reconfigured or renumbered.
