Is it Possible to Perform Soft Quota Reporting?

liesc · ‎2011-08-24

I’m looking for some help here…

Bank of America is looking for a report within OperationsManager which shows soft quotas that have been reached however (a simple yes itwas reached/no it wasn’t report), I cannot find anything like this, and thebank is asking for this report today.

According to Operations Manager documentation, the SoftLimit (aka soft quota) represents when a qtree is considered to be “almostfull.” That being the case, if a “qtree almost full” event is found, thesoft limit was hit. This does not appear to be happening.

Soft Limit

In "Space Availability" report, this option specifies the threshold in MBs at which a qtree is considered to be almost full. It is specified in the /etc/quotas file on the storage system

If there is indeed no report that shows if/when a soft quotawas reached, what alternatives do we have to give a yes/no answer as to whetheror not a soft quota was reached? Can a report/graph be created whichshows qtree size vs soft quota over time?

Thanks,

Chris

Hi Chris,

There is a report in DFM that does report on qtrees usage including soft quota.Below is the report on the same.

C:\Documents andSettings\Administrator>dfm report view qtrees-available 134

Object IDQtree Storage Server Volume Used AvailableSoft Limit Disk Space Limit Available (%)

--------- ---------------------- -------- ----- --------- ---------- -----------------------------

134 cifsonly sim1 CifsOnly 12320 8160 5120 20480 39.8

Totals 12320 8160 5120 20480 39.8

C:\Documents andSettings\Administrator>

Where Softlimit is soft quotaand diskspacelimit is the hard quota.

screenshot of SM2.0 for verification.

The following DFM event arerasied only when hard quotas are breached.

[root@lnx186-118 ~]# dfmeventtype list | grep -i qtree.kbytes

qtree-almost-full Warning qtree.kbytes

qtree-full Error qtree.kbytes

qtree-space-normal Normal qtree.kbytes

[root@lnx186-118 ~]#

Where as there is a way to generateevent or rather trap from filer when soft quota is exceeded as follows.

In the filer set the DFM serveras trap host.

Now I got the following events
