# StorageAnalyzer™ Data Types

# Filesystems [24]

This data type provides a high-level view of how much storage space is used and how much space is available in file systems at each host and domain location.

The Filesystems data type is time-averaged, just like the file space data. Selecting periods exceeding the collection period for non-trend reports will result in averaged data over time (but not over other classifications).

# Classifications

Name	Description
Domain	The domain where the file is located.
Host	The host (excluding the domain) where the file is located.
OS	The operating system of the host.
Mount point	The path to the directory where the file system is mounted.
Logical device	The name of the device (disk partition) containing the file system.
Measure	The type of data measured for the file system. Used Free Total

# Measurements

Name	Description	Unit of Measurement
Count	The number of file systems polls, one for each type of measurement (three for each file system).	Number
Measure size	The size of the file system which may be Free, Used, or Total (configurable) size depending on the Measure selected.	Megabytes

# ADSM [25]

This data type provides a high-level view of how the backup system in performing and which data is being backed up.

# Classifications

Name	Description
Domain	The host belongs to this domain.
Host	The host (excluding the domain) that is backed up.
OS reported by ADSM	The operating system of the host.
ADSM server	The server that performed the backup and has the backup in its tape archive.
Mount point	The path to the directory where the file system backup is mounted.
Days since last backup	The number of days since the last backup was performed on a file system.

# Filespace [29]

This data type is helpful to discover trends in file space usage, especially space usage of "cold data", which are rarely used. This can help in taking proactive measures to circumvent problems. The amount of file space a user or group uses per day can be reported, as well as the kind of files used and rate at which usage changes.

File space data is time-averaged. When creating a non-trend report (time is not selected as a classification) and the report is generated over a period longer than the data collection interval, the data is averaged on time but summarized over all other classifications.

# Classifications

Name	Description
Domain	The domain where the file is located.
Host	The host (excluding the domain) where the file is located.
File system	The name of the file system where the files reside.
Account	The file belongs to this account.
UID	The owner of the file.
GID	The group identifier of the file owner.
File type	The type of the file. text library binary etc
File status	The status of the file. plain compressed migrated
Read temperature	This shows how long ago the file was read (age is divided into discrete values). hot - 0 to 30 days old warm - 30 to 90 days old tepid - 90 to 360 days old cold - 360 to 720 days old frozen - more than 720 days old
Modify temperature	This shows how long ago the file was written (age is divided into discrete values). hot - 0 to 30 days old warm - 30 to 90 days old tepid - 90 to 360 days old cold - 360 to 720 days old frozen - more than 720 days old
Cost center	The file space use cost are distributed to these names.

Filespace Classifications

# Measurements

Name	Description	Unit of Measurement
Count	The number of polls performed.	Number
Number of files	The number of files accounted for.	Number
Logical size	The total (configurable) size of all the selected classification's files.	Megabytes
Physical size	The total block size of all the selected classification's files.	Blocks
Reported cost	The cost of file usage as reported by the clients.	Number

Filespace Measurements

Reported cost may be used to distribute the cost from accounts to cost centers using a mapping file with weights for each cost center. This "static" cost is calculated during disk accounting instead of costs calculated when a report is generated. The reported cost reflects the actual and "physical" amount of disk space used, not the "logical" file size, which may be bigger. When tracking a disk's usage, the actual disk space used is more important.

A file will be accounted as continually present until the following file accounting is performed. Removing the file just after the accounting is completed will not affect the current accounting period.

# Quota [40]

This data type tracks quota allocations and usage on NetApp's Ontap storage systems. When the client is installed on a filer, it collects information about the tree, user, and group quotas and how much of the specified space and file number quotas are used.

# Classifications

Name	Description
Filer	The filer/host (excluding the domain) where the quota applies.
ID	The ID number of the quota target.
Volume	The volume where the quota target is located.
Tree	The tree where the quota applies.
Quota specifier	The full specification of the quota target (Volume + Tree).

Quota Classifications

# Measurements

Name	Description	Unit of Measurement
Count	The number of times quota allocations and usage have been polled.	Number
Bytes used	The amount of space used within the quota target.	Kilobytes
Bytes limit	The amount of space that the quota target is limited to using.	Kilobytes
Bytes percentage	The percent of the limit used.	Percentage
Files used	The number of files used within the quota target.	Number
Files limit	The number of files the quota target is limited to using.	Number
Files percentage	The percent of the limit used.	Percentage

# Disk Utilization [59]

This data type merges the Filespace, Filesystems, and Quota data types. Its primary purpose is to report the size of disks combined with the space available in quota, used space, and used size of old or "frozen" files. This may give an excellent overall view of disk utilization and may help avoid disk space problems.

The Disk Utilization data type is time-averaged. Selecting periods exceeding the collection period for non-trend reports will result in averaged data over time (but not over other classifications).

# Classifications

Name	Description
Domain	The domain where the file system is located.
Host	The host (excluding the domain) where the file system is located.
OS	The operating system of the host.
Mount point	The path to the directory where the file system is mounted.
Logical device	The name of the device (disk partition) containing the file system.
Measure	The type of data measured for the file system. Used Free Total If Quota data type is included, the Quota limit is available. Also, all temperature labels are available.

Disk Utilization Classifications

# Measurements

Name	Description	Unit of Measurement
Count	The number of disk utilization records (one for each type of measurement).	Number
Measure size	The size of the file system or part of the file system. This can also be the size of a certain temperature value depending on the selected Measure.	Megabytes
Measure files	The number of the files in the file system or part of the file system (Used/Quota/Total number of files). This can be the number of files of a certain temperature value depending on the selected Measure. Also, Free = 0.	Number
