NVRAM Check Needs some work

All the checks are great. I’ve been using it for a week now and replaced all my other checks to NetApp appliances. However, the only problem I see is NVRAM. According to the MIB file, a value of 0 and 9 are good. Anything between is not good. I haven’t found a way to get an ok back if the values 0 and 9 are reported.

I tried to use the NAGIOS standard of -c 2:8 but I don’t see it working. Has anybody run into this and been able to overcome it?

Here is what the MIB for NetApp reports.
ok(1),
partiallyDischarged(2),
fullyDischarged(3),
notPresent(4),
nearEndOfLife(5),
atEndOfLife(6),
unknown(7),
overCharged(8),
fullyCharged(9)
