NetApp sensor

The NetApp sensor discovers storage resources that are related to network-attached storage (NAS) by extracting the data from Data ONTAP operating system with the SNMP protocol.

The sensor discovers such storage resources as storage filers, clusters, disk volumes, FC ports, physical disk drives, aggregates (represented as storage pools), NFS and SMB Services.

NetApp discovery is run by CustomMib2ComputerSystem that calls extension scripts. Additionally, the Snap Drive sensor is used on the host side to discover defined iSCSI disks. When data is discovered from both sources and it matches, a relationship between the host and array is created.

Object identifiers (OIDs)

The sensor uses the following high-level OIDs to retrieve the attributes:
  • General Information: .1.3.6.1.4.1.789.1.1
  • Virtual Filers: .1.3.6.1.4.1.789.1.16
  • Volumes: .1.3.6.1.4.1.789.1.5.8.1
  • Disk Drives: .1.3.6.1.4.1.789.1.6.10.1
  • Spare Disk Drives: .1.3.6.1.4.1.789.1.6.3.1
  • Cluster Disk Drives: .1.3.6.1.4.1.789.1.6.2.1
  • Qtree's : .1.3.6.1.4.1.789.1.5.10.1
  • Clusters: .1.3.6.1.4.1.789.1.25.1
  • Nodes: .1.3.6.1.4.1.789.1.25.2.1
  • Storage Pools: .1.3.6.1.4.1.789.1.5.11.1
  • FC Cards: .1.3.6.1.4.1.789.1.17.17.1.1
