Best Practices for OM Reporting

Are there any best practices around best reports for management types to look at?  In other words, what reports are generally sent to storage administrators managers for better forcasting/understanding the environment.

Also, are there any scripts available for automated posting of these type of reports to a website so emailing and unzipping is not needed.

By default, these schedules reports are archived in dfm under the following location.

Reports Archival Directory       /opt/NTAPdfm/reports

If you wish to make these reports accessible via web, what one can do is change this default location to a web location where a apache or similar is running.So this can be made accessible via web.

The option to change the location is below.

[root@lnx~]# dfm options list reportsArchiveDir
Option            Value
----------------- ------------------------------
reportsArchiveDir /opt/NTAPdfm/reports/
[root@lnx ~]#

Re: Best Practices for OM Reporting

Since they are all saved as zip files, would you need to extract them and then post them?

Re: Best Practices for OM Reporting

No,Only the email output is zipped.

[root@lnx reports]# dfm report schedule list

Re: Best Practices for OM Reporting

Some useful reports to create, that you can create to help you better.

  • Volume and Snapshot reserve usage in one report

          Create the following custom report for the same as below.

dfm report create -R SnapReserve -f  Volume.Aggregate.Filer=StorageSystem,Volume.Aggregate=ContainingAggr,Volume.Name=VolName,Volume.Total=VolTotal,Volume.Used=VolUsed,Volume.Available=VolAvail,Name=SnapName,Total=SnapResTotal,

Used=SnapResUsed -L "Volume And Snapshot Capacity Usage"   volume-and-snapshot-usage

  • When should I buy new disks.

You can look at "Raw Capacity Used vs Total" graph for each filer to check the physical capacity usage or at a group level.

To check the actual usage, see "Volume Capacity Used vs Total".

Raw Capacity Total is the some of all disk sizes (data, parity, dual parity and spare disks).

Raw Capacity Used is the some of all in-use disk sizes (data, parity and dual parity).

  • How to know if aggr space is completely committed, but the vols on that aggr still have space left ?

You can create the following custom report:

dfm report create -R Aggregate -f FullName=AggrName,Status=AggrStatus,Used=AggrCapUsed,UsedPct="AggrCapUsed%",BytesCommitted=AggrBytesCommitted,BytesCommittedPct="AggrBytesCommitted%",SpaceAvailable=AggrCapAvail,AvailablePct="AggrCapAvail%",TotalSpace="AggrCapTotal", -L "Aggregate Used vs Committed Space" aggr-used-committed

Bytes Committed - Amount of aggregate space committed to flexible volumes.

Bytes Committed (%) - Percentage of aggregate space committed to flexible volumes.

Used Capacity - Amount of space in the aggregate used by flexible volumes.

Bytes Used (%) - Percentage of aggregate space used by flexible volumes.

Total Space - Total capacity of this aggregate.

  • How can I find the disk sizes after right-sizing

We show the marketing size of the disks and not the right size capacity of the disks in reports.
We collect right size information for disks through SNMP (but it does not exactly match the value reported by "sysconfig -r" command).
This is available through custom reports through the "UsedSpace" field in the "Disk" catalog.
Note: right size information is not available for spare disks because this is not available through SNMP.

dfm report create -R disk -f "Name,Filer,UsedSpace:MB ,Size:MB" -L "Right Sized Disk" disk-size-report

PS:Thanks to shekar raja for all the reports, that he documented.

Re: Best Practices for OM Reporting

You can view the scheduled runs from OM itself. Just navigate to Reports -> Schedule -> Saved Reports.

Re: Best Practices for OM Reporting

We started using a tool for our 3PAR arrays an we pointed it at our NetApp filers and it is working pretty good for us. The tool is called Arxview, www.arxscan.com they have trial version.

Re: Best Practices for OM Reporting

Hi Adai,

"When should I buy new disks" - how can I have it on a single page ?

I'm particularly interested in "Raw Capacity Used vs Total" graph, it would be really handy to have it on one page ..

Thanks,

Vladimir
