DFM commands to list avg-latency on luns within a time frame

[netappmagic]

I am seeking for command line to list the highest peak latency within a time window on all individual luns in a volume.

if we can not do that in one command, then what about just list the latency on an particular lun?

I don't feel i can do that in GUI, so, looking for your help on CLI. THANKS!

You should be able to do it with dfm perf data retrieve

hi Adai,

Could you please show me a full command as an example?

lun stats -c 5 -i 5 <lun path>

Sathish,

I am asking for a DFM command and about historic data on a particular time window.

Thanks for your reply.

Let me help you teach fishing rather than catch fish.

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 ]

It does not tell you what correct values are for things like:

            -b start-time                             (format YYYY-MM-DD hh:mm:ss)

            -e end-time                              (format YYYY-MM-DD hh:mm:ss)

            -M month ...                          

            -D weekday ...                                  

            -T time-range                         

            -m statistical-method              (values min, max, mean, value_at_percentile)

            -P percentile-value                  (decimal, e.g. 95 for 95th percentile)

            -S data-advance-method       

            -s sample-rate                        

            -x output-format                                 Need CSV file output!

            -R                                                      

1) To get the data for the last 5 minutes :

dfm perf data retrieve -o mpo-vsim16 -C volume:total_ops -d 300

2) To get the data between two different intervals:

dfm perf data retrieve -o mpo-vsim16 -C volume:total_ops -b "2013-08-20 07:50:00" -e "2013-08-20 8:00:00"

3) To get the data of a View for last 5 minutes:

dfm perf data retrieve -o mpo-vsim16 -V "Volume Summary View" -d 300

4) To get the Minimum value for the Specified interval of 5 minutes in a View :

dfm perf data retrieve -o mpo-vsim16 -V "Storage System Summary View" -d 300 -m min

5) To get the list of Views available :

dfm perf view list

Hope this helps.

Hi,

for the historic data&colon;

dfm perf data retrieve -o "Ctrl_name" -C "counter_name" -D "day_range" -e "end_date" -b "begin_date" -T "time_range" -m max

for example the maximum processor_busy during Monday to Friday between 7AM to 7PM through the 1st and 30 October

dfm perf data retrieve -o "CTRL_NAME" -C system:avg_processor_busy -D Mon,Tue,Wed,Thu,Fri -e 2013-09-30 -b 2013-09-01 -T 07.00-19.00 -m max
