Statistics Tools Terminology and Definitions

Oracle FS System statistics are organized by component, subcomponent, and statistics type.

The statistics are grouped by component, such as RAID, any subcomponent, and statistic type, such as user interface. The statistics presented vary by component. For example, the statistics generated for RAID are different than the statistics generated for SAN. The table provides terminology and definitions of the component, subcomponents, statistics type as well as how the statistics are organized. For a detailed description of the component and subcomponent statistics, refer to the fsstatsdefinitions.html file which is part of the statistics tool package.

Table 1 Statistics terms defined
Term	Description
Component	An Oracle FS System software module. The following software module components provide data that is included in the statistics file: Module Description BS Block Services. Supplies all read and write cache management, including mirroring. CIFS Common Internet File System. Provides Windows and other CIFS clients access to the Oracle FS System filesystems from network shares. DMS Diagnostic and Monitoring Services. Runs diagnostics and monitors various components of the system. DPS Data Protection Services. Provides the functions necessary for backup services. MQFS Meta File System. Provides a protocol neutral file system that supports files, directories, and other filesystem objects. NFS Network File System. Provides UNIX, Linux, and other NFS clients access to the Oracle FS System filessystem by means of mount points. RAID Redundant array of independent disks (RAID) Provides a disk subsystem that consists of a set of drives and a controller that operate as a single logical drive. SAN Storage Area Network. Provides the host network with a SCSI interface to the Oracle Flash Storage System on a SAN Controller to LUNs. VS Virtual Server Manages NAS-only File Servers that are used to assign security, network, and protocol access attributes. These attributes apply to all filesystems associated with the File Server. Includes virtual interfaces (VIFs).
Duration	The amount of time in seconds that data was collected.
Statistics bundle	The portion of the system information collection that contains statistical data.
Statistics column	A column heading in the statistics output that identifies a discrete statistic, such as `Write_through_Ops` (the number of write-through operations). These column headings are listed and described in the HTML file fsstatsdefinitions.html. The fsstatsdefinitions.html is downloaded with the statistics tools.
Stats time	The time the system began collecting data for the software module component.
Statistics type	The type of statistical data. Each component can contain different types of data: Error Error statistics count operations that have failed. UI User interface statistics are user-visible statistics normally shown on the GUI. General General statistics contain any detailed statistics that a component collects that cannot be classified as error or user visible statistics.
Subcomponent	A constituent part of a primary component. Subcomponents are also known as resource types. The value of none is displayed if there is no subcomponent.

For a detailed description of the component and subcomponent statistics, refer to the fsstatsdefinitions.html file that is part of the package. The package includes the Oracle FS System Statistics Parser and Oracle FS System Statistics Formatter tools. The package is available for downloading from the Oracle FS System.
