mrtg-ntap-probe can probe for Network Appliance NetCache caching appliance and NetApp Filer.
mrtg-ntap-probe retrieves the disk and file (inode) utilization by volume or quota tree name, so you do not need to find the right OID, which might change over time as you add and/or remove volumes and quota trees.
You need a recent release of mrtg 2.x, perl 5.003 or better, a NetApp NetCache appliance with NetCache release 5.1 or better and/or a Network Appliance Filer running Data Ontap 6.0 or better.
If you have a Network Appliance service contract and access to their software tools library on now.netapp.com, you should also take a look at their mrtg-filer and mrtg-netcache packages!
What's New in This Release:
· This release adds reporting of A-SIS de-duplication disk space savings, and a new "vol-ds" report (volume disk space saved).
· It has been adapted for Data ONTAP 7 and tested with version 5.8.4 of Perl (Solaris 10 native /usr/bin/perl), version 7.2.4P5 of Data ONTAP, and version 5.6.2R2 of NetCache.
