With LLD provided monitoring of sort of dynamic data becomes very simple. For example I've managed to create a simple OSFP monitoring template using Discovery rule, 2 item prototypes and 1 trigger prototype. Though I couldn't manage to create a graph prototype because of graph name uniqueness issue (it doesn't handle

macro, I guess), though if any change to ospfNbrTable occurs, for example, neighbour disappeared for some reason, any graphical alerting becomes unavailable, because LLD marks neighbour-related items as 'unsupported' and deletes all triggers based on them.
