To use the Reporting function, the ETERNUS SF Storage Cruiser Standard Edition license is required.
For the ETERNUS Disk storage system to which the above license is not registered, reporting is not available. If the license is not registered for the ETERNUS Disk storage system and reporting is desired, register the license.
Information
The required license for ETERNUS Disk storage system is checked when the report information collection command is run. For this reason, even if the license is deleted while in use, already collected information is output in the report.
Specify the report information retention period in the information stack file by setting up a policy.
See
Refer to "A.11 policy.conf Parameter" for information on how to set up a policy.
Setup from Web Console
Select Storage from Web Console to activate the Reporting function.
Periodic command execution of the Reporting function can be started and stopped on a per storage basis. Enabling the Reporting function runs the report information collection command at the 5th minute of every hour and the report creation command at 6:30 AM on the 1st of every month periodically. The period of the report made by periodic command execution is one month from 0:00 of the 1st of the previous month to 0:00 of the 1st of the month.
Set Up Periodic Command Execution by Creating Unique Application
If you want to run the report creation command with more detailed settings than the command execution interval set up from Web Console, perform the following operations:
Use the operating system periodic execution function
Create an application to periodically invoke the report creation command
Note
For report period information specified for option of the report creation command, specify a proper value every time.
A general charging method devised by the Reporting function is to charge usage fees for volumes used by servers within a report output period, which is calculated on a per server basis.
Server administrator privileges are required to view the report file.
The calculation formula for fees charged for volumes is as follows:
Fees charged for volume = Unit price (a) * Volume allocation (b) * Volume allocation time (c)
The following is an example of unit price per RAID level:
RAID Level | Unit Price per MB and per Hour |
|---|---|
RAID0 | 1 dollar |
RAID1 | 2 dollars |
RAID1+0 | 3 dollars |
RAID5 | 4 dollars |
RAID6 | 5 dollars |
RAID5+0 | 6 dollars |
Fees charged for server = Sum of fees charged per volume
The report file configuration output by the Reporting function is as follows:
Server information
ETERNUS Disk storage system information
Allocated volume information
Information for volume (disk type, RAID level, etc.)
Allocated volume information
...
ETERNUS Disk storage system information
...
Server information
...To calculate fees charged for volumes allocated per server, for example, create an accounting application to perform the following processing (element name in the brackets):
foreach <server information (Servers)> {
Fee charged for server = 0
foreach <ETERNUS Disk storage system information (DiskArrays)> {
foreach <allocated volume information (Volumes)> {
Obtain type of RAID group from RAID information (RAIDGroup).
Get unit price from fee sheet according to obtained RAID group type. ... a
Obtain volume allocation (capacity) from volume information (Volume). ... b
Obtain volume allocation time (difference between end and start) from volume allocation information (Allocation). ... c
Fee charged for allocated volume = a * b * c
Fee charged for server += Fee charged for allocated volume }
}
Output the fee charged for server
}Calculate fees charged for server (charged for volume 1 and volume 2).
The conditions per volume are as follows:
Volume1
RAID level: RAID0 (unit price: 1 dollar)
Volume allocation: 100 MB
Volume allocation period: 12/1 5:00 - 12/2 1:30 (20.5 hours in all)
Volume2
RAID level: RAID6 (unit price: 5 dollars)
Volume allocation: 500 MB
Volume allocation period: 12/10 11:00 - 12/10 14:00 (3.0 hours in all)
Fee charged per volume is as follows:
Fee charged for Volume1
1(dollar) * 100(MB) * 21(hour) = 2,100(dollars)
Fee charged for Volume2
5(dollars) * 500(MB) * 3(hour) = 7,500(dollars)
Fee charged for server is as follows:
Fee charged for server
2,100(dollars) + 7,500(dollars) = 9,600(dollars)
