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

.

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

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,

Bipul
