I see. I actually use the UnDP Poller Status resource on our node details pages, which combines all UnDPs into a single table, but I guess one downside is that ALL UnDPs go int a single table. But, if you group your UnDPs like we do, it groups them in the table as well.
Let me know how you get the alerting working. I wasn't able to get alerting working the way I wanted when I was polling the table that way. I think it was due to the dynamic and tabular nature of the higher OID rather than the more specific one. I was probably doing something wrong, but it was just easier to poll the leaf OID since you always get only 1 simple value.
