NetApp Host and VM File Systems data collector Edit on GitHub Request doc changes

Use the NetApp Host and VM File Systems data collector to retrieve file system details and storage resource mappings for Microsoft Windows host and VM file systems and for supported Linux VMs that are annotated with the configured Compute Resource Group (CRG).

General Requirements

  • You should annotate a group of hosts and virtual machines that have common operating system credentials using the same Compute Resource Group annotation.

  • Each group has an instance of this data source discovering file system details from those hosts and virtual machines.

  • If you have an instance of this data source for which the success rate is low (for example, Cloud Insights is discovering file system details for only 50 of 1000 hosts and virtual machines in a group), you should move the hosts and virtual machines for which discovery is successful into a separate Compute Resource Group.

  • FC-connected hosts MUST be successfully resolved by Auto Host Resolution before they can be acquired by the Host FSLU data source.

  • Auto Host Resolution must be able to extract and parse a hostname from the information provided by the switch (port alias, zone or SRM) before host FSLU can be deployed. It is mandatory that the switch environment be evaluated for accuracy (or even the mere presence/availability of this information) prior to attempting auto resolution.

  • The Cloud Insights administrator must have knowledge of the general OS type (Windows, Linux, etc.) running on each host, so that the proper Compute Resource Group annotation can be applied to a given group.

Microsoft Windows Requirements

  • This data collector uses Window Management Instrumentation (WMI) data structures to retrieve data.

    This service must be operational and available remotely. In particular, port 135 must be accessible and must be opened if behind a firewall.

  • Windows domain users must have the appropriate permissions to access WMI structures.

  • Administrator permissions are required.

Linux Requirements

  • This data collector uses a Secure Shell (SSH) connection to execute commands on Linux VMs.

    The SSH service must be operational and available remotely. In particular, port 22 must be accessible and must be opened if behind a firewall.

  • SSH users must have sudo permissions to execute read-only commands on Linux VMs.

    You must use the same password to log in to SSH and to answer any sudo password challenge.

Usage reccomendations

  • You should annotate a group of hosts and virtual machines that have common operating system credentials using the same Compute Resource Group annotation.

    Each group has an instance of this data collector discovering file system details from those hosts and virtual machines.

  • If you have an instance of this data collector for which the success rate is low (for example, Cloud Insights is discovering file system details for only 50 of 1000 hosts and virtual machines in a group), you should move the hosts and virtual machines for which discovery is successful into a separate Compute Resource Group.

Configuration

Field Description

User Name

Operating system user with appropriate rights to retrieve file system data. For Windows operating system users, this must include the domain prefix.

Password

Password for the operating system user

Compute Resource Group

Annotation value used to flag host and virtual machines for the data collector discovers file systems.

A blank value indicates that the data collector discovers file systems for all hosts and virtual machines not currently annotated with a Compute Resource Group.

Advanced configuration

Field Description

Inventory poll interval (min)

Interval between inventory polls. The default is 360 minutes.
