OM query dfm perf data

martin_pauke · ‎2011-09-16

Hi,

is it possible to get more than one measurepoint with one query (-C aggregate:user_writes,user_reads...) (this example didn,t work).?

i use this :

dfm perf retrieve -o file:aggrname -C aggregate:user_writes -M Month -s 3600

but i need all existig information like user_writes user_reads total_transfers.

Regards Martin

You should specify the counters in comma separated format as (-C aggregate:user_reads,aggregate:user_writes,aggregate:total_transfers).

Object name was missing before user_reads in you example.

One more thing is your command is wrong. It should be like dfm perf data retrieve -o <object_name> -C <counter_name> ...

You can see the usage details by using the command like

$dfm perf data retrieve help

NAME
retrieve -- This command allows you to extract the counter data
with supported statistical calculations on them.

SYNOPSIS
    dfm perf data retrieve { [ -o object-name-or-id ... ] [ -C perf-counter ... ]
                        [ -V view-name ] }
                [ -d duration ] [ -b start-time ] [ -e end-time ]
                [ -M month ... ] [ -D weekday ... ] [ -T time-range ... ]
                [ -m statistical-method [ -P percentile-value ]
                        [ -S data-advance-method ] ]
                [ -s sample-rate ] [ -x output-format ] [ -R ]

Here it clearly specifies the object name need to be there in the dfm perf data retrieve command.

This is the output of my problem:

This worked

smc-vm-025:~ # dfm perf data retrieve -o smc-na001-pb.smc.xxx.net:f1_aggr0_mir_15k -C aggregate:user_reads -M Sep -s 3600

Timestamp smc-na001-pb.smc.xxx.net:f1_aggr0_mir_15k:user_reads

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

2011-09-09 14:04:43 277.800

2011-09-09 15:04:43 175.867

.

This not:

smc-vm-025:~ # dfm perf data retrieve -o smc-na001-pb.smc.xxx.net:f1_aggr0_mir_15k -C aggregate:user_reads,aggregate:user_writes -M Sep -s 3600

Error: Expected object:counter; found aggregate:user_reads,aggregate:user_writes.

And this Tables exists:

smc-vm-025:~ # dfm perf data retrieve -o smc-na001-pb.smc.xxx.net:f1_aggr0_mir_15k -V "Aggregate Summary View" -M Aug -s 3600

Timestamp smc-na001-pb.smc.xxx.net:f1_aggr0_mir_15k:user_reads

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

No data available

Timestamp smc-na001-pb.smc.xxx.net:f1_aggr0_mir_15k:user_writes

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

No data available

Timestamp smc-na001-pb.smc.xxx.net:f1_aggr0_mir_15k:cp_reads

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

No data available

Timestamp smc-na001-pb.smc.xxx.net:f1_aggr0_mir_15k:total_transfers

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

No data available

So, the problem still exists.

The 'No data available' error could be because you are asking for Aug month data and the perf data for 'Aggregate Summary View' by default stores 1 week data.

Can you please verify against Sep month ? Also, post the sampling rate and sampling duration for the 'aggregate' object of this host using 'dfm perf data describe' CLI

martin_pauke · ‎2011-09-16

This should only a example for the existing tables.

This is the main problem:

smc-vm-025:~ # dfm perf data retrieve -o smc-na001-pb.smc.xxx.net:f1_aggr0_mir_15k -C aggregate:user_reads,aggregate:user_writes -M Sep -s 3600

Error: Expected object:counter; found aggregate:user_reads,aggregate:user_writes.

All other things are only to explain.

Hello,

when you specify the comma in between the counter name on the cli, still -C need to be there. Otherwise it will give you error

Correct syntax would be either

$ dfm perf data retrieve -o <object name> -C aggregate:user_reads, -C aggregate:user_writes -M Sep -s 3600

or

without comma separated cli,

$ dfm perf data retrieve -o <object -name> -C aggregate:user_reads -C aggregate:user_writes -M Sep -s 3600

Now try again.

Thanks,

Bipul

Ok. It works now - but --- now the next question . Is it possible tho put the output in two collums. Actual the output was generated sequentialy.

smc-vm-025:~ # dfm perf data retrieve -o smc-na001-pb.smc.xxx.net:f1_aggr0_mir_15k -C aggregate:user_reads -C aggregate:user_writes -M Sep -s 3600

Timestamp smc-na001-pb.smc.xxx.net:f1_aggr0_mir_15k:user_reads

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

2011-09-09 14:31:44 507.900

2011-09-09 15:31:44 220.283

.

Timestamp smc-na001-pb.smc.xxx.net:f1_aggr0_mir_15k:user_writes

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

2011-09-09 14:31:44 507.900

2011-09-09 15:31:44 220.283

.

martin_pauke · ‎2011-09-16

OK. I found the solution.

dfm perf data retrieve -o smc-na001-pb.smc.xxx.net:f1_aggr0_mir_15k -C aggregate:user_reads -C aggregate:user_writes -M Sep -s 3600 -x TimeIndexed

is what i need.

Thanks for your great support

Martin

bipulm · ‎2011-09-16

Hello,

"-x TimeIndexed" will give you the column by column output, but it ignores the second information on the time column of the CLI output.

Thanks,

Hello again,

i have another "little" problem.

I could list this information with :

dfm perf counter list filer:logical_replication_destination:*:*:*

i got for example thist output:

.

logical_replication_destination L5S:/vol/f5_vm_esx81/lun81->LXSAN3:/vol/f3_vm_esx81_mir/lun81 num_restarts none basic

.

Now i would query this Objetc L5S:/vol/f5_vm_esx81/lun81->LXSAN3:/vol/.....

now my problem:

dfm perf data retrieve -o filer:L5S/vol/f5_vm_esx81/lun81->LXSAN3:/vol/f3_vm_esx81/lun81 -C logical_replication_destination:network_read_rate -s 900 -M SEP

will not work because : is a delimiter and the Object has : in his name. What is the right command Syntax with this kind of Object?

Regards Martin

pagrawal · ‎2011-09-19

Hi Martin,

Its recommended to use object Id instead of Object name.

Please try using object Id for -o option, or you can try putting double quotes on the object name .

Thanks.

martin_pauke · ‎2011-09-19

Ok, where could i get the object Id for this object? I have searched in many Documentatitions but i found no example. I know only this command to resolve the objetcs:

dfm perf counter list filer:*:*:*:*

Regards

Martin

bipulm · ‎2011-09-19

Hello Martin,

You can get the object id for various instances under different object type by executing the following command

$ dfm <object-type> list -q <filer>

Like for example where daood is the filer

$dfm aggr list -q dawood

$ dfm qtree list -q dawood

$dfm volume list -q dawood

The above command output having one column is "ID" which specifies the object id corresponding to the instance.

Now this object-type should be listed when you use the "dfm help" command like if you execute the below command

$dfm help

This will list aggr, lun, volume, qtree on the output. You can try also "$dfm <object-type> list help" for details.

Thanks,

Bipul

Hi,

I don't think 'dfm perf data retrieve' CLI supports unmanaged objects. 'logical_replication_destination' is an unmanaged object. Further PA doesn't collect data for this object by default.

The workaround for you could be

* Create a custom view

* Add the selected counter/instance pair (i.e., logical_replication_desination:<counter-name>:<instance-name>)

From this moment, PA shall start collecting data for the counter/instance pair.
