Sometimes it is usefull to know how much items in table have some value.

It would be nice to have SNMP check like:

.1.3.6.1.4.1.727.7.2.20.10.1.3[1]

i.e., count of dynamic indexes in table, thos values (converted to string) matches regexp "1" (or, maybe, "online", if needed proprietary MIB installed and enumeration 1 <-> "online" is available).
