automatic reports in performance advisor

[TThaens24]

Hello all,

We are trying to follow-up the performance on our NetApp boxes.

The first step is checking the CPU and disk IOPS.

With operations manager, I was able to get the CPU graph automatically in our report (using wget to download the biggraph).

But the disk performance report in operations manager is a bit basic.

Using the NetApp management console, we get nice images from performance advisor. But to get these in a report, someone has to group through all the disks, and saving the image this way.

Is it also possible to get images from performance manager in an automatic way?

Kind regards

It's not possible to do automatically.  But using following CLI you can get the data for the each object.

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 ]

Ex:

dfm perf data retrieve  -o 1232 -V "Disk Summary View" (For multiple objects you have to give multiple objects in this CLI or write a script using this cli)

Using some graphing tool these data can be converted into a chart.

Hi,

Thanks already, something like this was exactly what I was looking for.

But it seems that dfm perf data retrieve does not exist:

root@bru0268x:/> dfm perf data retrieve
Error: Unknown command: retrieve

Use "dfm perf help" or "dfm perf data help" for usage information.
root@bru0268x:/>

Looking what dfm perf data sub-commands exist, I get:

root@bru0268x:/> dfm perf data help

NAME
    data -- Manage performance data

SYNOPSIS
    dfm perf data list [-v | -h] [ -o <object-name-or-id> ]  [ -G <counter-group-name> ]

    dfm perf data describe [-v] <counter-group-name> <object-name-or-id>

    dfm perf data modify [ -f ] <counter-group-name>
                [ sampleRate=<sample_rate> ] [ collectionPeriod=<collection-period> ]

DESCRIPTION
    The perf data commands allow the user to list and modify
    the performance data that is collected by the server

root@bru0268x:/>

I did find a dfm perf view retrieve command, but this doens't realy gives me usefull info:

dfm perf view retrieve [ -a <appliance-name-or-id> | -g <group-name-or-id> ]
            [ -o <perf-object> ] [ -i <perf-instance> ]
            <view-name> <starttime> <endtime>

Kind regards

Hi,

Sorry the data retrive CLI will be available in DFM 4.0.

perf view retrieve do same job. See below example

dfm perf view retrieve -a zidane "Disk summary view" "2009-08-20 00:00:00"  "2009-12-12 00:00:00" | more

Above CLI returns the data for given time period for all the disks in a Zidane Storage system.

OK,

getting a bit further.

And how should I interprete this data?

How can I know from which disk this is?

Here is the example to get the details. Here Zidane is a Storage System.

[root@wills ~]#  dfm perf view retrieve -a zidane "volume summary view" "2009-08-20 00:00:00"  "2009-12-12 00:00:00" | more

View Name: Volume Summary View

View Sample Rate: 60 seconds.

View Sample Buffer: 604800 seconds.

Thanks,

This indeed provided me the correct info's.

Also with the "dfm perf view list" I found all different kinds of views I could retrieve.

I also found a nice tool which can make graphs from data on a linux cli.

If anyone else need such a thing : gnuplot

Kind regards

[tgottenoef]

hallo tthanes24,

you mentioned, you could wget the biggraph, for example cpu1m graph. Could please post me the path to get this as picture format. I only get logo.gif and others but not the graph.

Thanks Thomas
