Hello everyone,
I've been working on a project which uses netsnmp to monitor the backend
systems. However I found out that the returned data had been mismatched
whenever it's retriving information from hrStorageTable. Following is what i
entered on the command:
"snmpbulkget -v2c -c amail 4.4.4.31 hrStorageIndex hrStorageType
hrStorageDescr hrStorageSize hrStorageUsed"
and the following is what bulkget returned, notice *index 6*:

It seems that bulkget has automatically shift "hrStorageUsed" upwards by
three positions. It looks like that it couldn't get the usage information
for the device type "hrStorageOther", but I suppose "null" or "0" should be
returned instead or "hrStorageOther" devices should be filtered out. I think
there are must someone out there encountered this problem before, please
give me some suggestions. Thanks in advance!!
