Hi StoRage,

I discussed this few weeks ago with a NetApp engineer. Unfortunately, this is a "by-design" behaviour: MIB values are loaded during boot and in a random fashion so there is no way to forecast (or enforce) what MIB index will be for a particular volume. So it seems that there is no other way than manually modifying MRTG configuration file to take the changes into account.

When asked how Data Fabric Manager can handle this, the answer was that since it relies on a database, DFM is clever enough to update the index to check.

I hope this will help. Kind regards,

To: toasters@mathworks.com cc: Subject: SNMP values keeps changing after every reboot. any solution to fix this?

Every time the filer is rebooted. the snmp values for disk changes. This affects our mrtg monitoring. Is there a script that helps overcome this issue? How are others monitoring disk usage using mrtg? TIA

After last reboot:

NETWORK-APPLIANCE-MIB::dfFileSys.1 = STRING: "/vol/vol1/" NETWORK-APPLIANCE-MIB::dfFileSys.2 = STRING: "/vol/vol1/.snapshot" NETWORK-APPLIANCE-MIB::dfFileSys.3 = STRING: "/vol/vol7/" NETWORK-APPLIANCE-MIB::dfFileSys.4 = STRING: "/vol/vol7/.snapshot" NETWORK-APPLIANCE-MIB::dfFileSys.5 = STRING: "/vol/vol6/" NETWORK-APPLIANCE-MIB::dfFileSys.6 = STRING: "/vol/vol6/.snapshot" NETWORK-APPLIANCE-MIB::dfFileSys.7 = STRING: "/vol/vol2/" NETWORK-APPLIANCE-MIB::dfFileSys.8 = STRING: "/vol/vol2/.snapshot" NETWORK-APPLIANCE-MIB::dfFileSys.9 = STRING: "/vol/vol0/" NETWORK-APPLIANCE-MIB::dfFileSys.10 = STRING: "/vol/vol0/.snapshot" NETWORK-APPLIANCE-MIB::dfFileSys.11 = STRING: "/vol/vol5/" NETWORK-APPLIANCE-MIB::dfFileSys.12 = STRING: "/vol/vol5/.snapshot" NETWORK-APPLIANCE-MIB::dfFileSys.13 = STRING: "/vol/vol4/" NETWORK-APPLIANCE-MIB::dfFileSys.14 = STRING: "/vol/vol4/.snapshot" NETWORK-APPLIANCE-MIB::dfFileSys.15 = STRING: "/vol/vol3/" NETWORK-APPLIANCE-MIB::dfFileSys.16 = STRING: "/vol/vol3/.snapshot"
