For large Netapp volumes where 64 bit counters would be appropriate, but Netapp doesn't support them, a Netapp stores used blocks across two 32bit SNMP oids: dfHighUsedKBytes and dfLowUsedKBytes.
I've successfully used these in a custom data collector and in an altered utilization graph for Netapp filesystems. So, on my OS tab, I can now see the proper amount of 'Total bytes' and if I click on a filesystem, the graph is correct. However, what's incorrect is 'Used Bytes' on the OS tab. This is due to the fact that this page looks for 'usedBlocks' as collected by the FileSystem template. usedBlocks is a single OID Data Source, but to get it to work properly, it needs to be able to use the same algorithms I've used in the data collector and custom graphs... So, how can an SNMP Data Source like 'usedBlocks' be configured to use multiple SNMP oids to create a calculated result? For those of you with NetApps and large volumes, how have you solved this problem?
