what is the command in PA to increase the default buffers

Hello all

I need to increase Performance Advisor's ability to retain performance data from 5 days to 30 days or more on all default views.  I heard it is a CLI option, where can I set that option?

Thanks, Emanuel

Re: what is the command in PA to increase the default buffers

Will give the details of current retention.

[root@lnx ~]# dfm perf data list
Counter Group             Host Name                                Sample Rate     Retention Period Max Records Used Space      Max Projected Space
------------------------- ---------------------------------------- --------------- ---------------- ---------- --------------- --------------------

Use dfm perf data modify to change the retention.

[root@lnx ~]# dfm perf datas modify help

NAME

    modify -- Modify the interval and collection details for a counter group

SYNOPSIS

    dfm perf data modify [ -f ] -G <counter-group-name> [ -o <host-name-or-id> ]

                [ -s <sample-rate> ] [ -r <retention-period> ]

DESCRIPTION

    Modify the interval and retention details for a counter group.

    Specify a positive number, optionally followed by a time period

    suffix to indicate seconds, minutes, hours, days, or weeks.

    The default time period suffix is seconds.

    'host-name-or-id' is mandatory for default counter groups.

    Use -f option to force the change of sample rate and

    retention period when the number of records for

    the view decreases.

Re: what is the command in PA to increase the default buffers

Okay .. getting closer ... here is what I have found ( see below ) ... the 604800 is the 7 day collection period but I noticed that the used space is all different.  I do not need to bump all these up but now i have new questions

Looking at the list of counter groups, I can see that I would want to increase "system basic", "disk basic", "aggregate basic", "NFS basic", "volume basic", and "NIC basic".  I will be using the view in "View > Logical or Physical > controller > object" to dive down into a specific volume or disk to look at what the object was doing when a client side alarm goes off when it complains that our filers are slow.  This is a strict NFS environment, no SAN or CIFS or iSCSI.

When I look at the collection period, I can do the math to bump up the coverage to 30 days ... if I do this on each group, does the "Max Records" increase as well with the "Used Space"?  Is the Max Records something I can or need to modify?  Is the Used Space a reflection of how large the data has grown since it has been collecting?

If I increase the collection period which will increase the size on disk for storing the data, is there a way I can size?

Re: what is the command in PA to increase the default buffers

Max records is=Collection Period/Sampling interval.

In your case =604800/60=10080. This will change automatically when you change your collection period or sampling.

If you reduce any of these that might reduce the max records then you must you -f options in the perf data modify.

-f it forces the change of sample rate and       retention period when the number of records decrease

Used size is the currently used size.

Projected size is the max size to which this can grow with the current sampling and collection period. this field is available starting next release.

Re: what is the command in PA to increase the default buffers

Okay, I have increased them to 30 day increments on the NAS/NFS specific counters ( ignoring iSCSI and FCP SAN counters ).  I will check these next week to see if we keep longer than 7 days on default views.

Re: what is the command in PA to increase the default buffers

Retention periods are associated with counter groups. Data for the

default views are fetched from these counter groups. For example, there

is a counter group called "System Archive", whose data is shown in

"Storage System Summary View" default view. The command to manipulate

retention period (and sampling rate) of a counter group is "dfm perf

data modify".

Example:

To increase the retention period of "System Archive" counter group from

1 year to 2 years, the command would be

dfm perf data modify –f "System Archive" collectionPeriod="2 years"

"dfm perf data list" CLI can be used to list all the counter groups.
