LUN stats via DFM console

steven_jenner — Thu, 05 Jun 2025 06:38:17 GMT

Hi I am trying to get LUN statistics for a specified time scale output via the DFM console. I previously ran a script which outputted information as below:

Timestamp       FASA:/fcp_dw/vmfs_vol1:read_ops
-------------------------------------------------------------------------------
2011-12-01 16:16:40     372.000

Timestamp       FASA:/fcp_dw/vmfs_vol1:avg_latency
-------------------------------------------------------------------------------
2011-12-01 16:16:40     8.630
2011-12-01 16:17:40     9.253

Unfortunately I cannot locate the script I ran last time and am having no luck searching for it.

Can anyone help with the appropriate DFM command/s to get the above information specfiying a particular start and end point.

Thanks in advance,

Steve.

I have found the information I was looking for, in order to extract the required information from the command line I entered the following commands:

dfm perf data retrieve -o FASA:/fcp_dw/vmfs_vol1 -C LUN:total_ops -b "2012-01-05 16:30:00" -e "2012-01-06 09:30:00" -s 60 >> total_ops.txt

dfm perf data retrieve -o FASA:/fcp_dw/vmfs_vol1 -C LUN:read_ops -b "2012-01-05 16:30:00" -e "2012-01-06 09:30:00" -s 60 >> read_ops.txt

dfm perf data retrieve -o FASA:/fcp_dw/vmfs_vol1 -C LUN:write_ops -b "2012-01-05 16:30:00" -e "2012-01-06 09:30:00" -s 60 >> write_ops.txt

dfm perf data retrieve -o FASA:/fcp_dw/vmfs_vol1 -C LUN:other_ops -b "2012-01-05 16:30:00" -e "2012-01-06 09:30:00" -s 60 >> other_ops.txt

dfm perf data retrieve -o FASA:/fcp_dw/vmfs_vol1 -C LUN:read_data -b "2012-01-05 16:30:00" -e "2012-01-06 09:30:00" -s 60 >> read_data.txt

dfm perf data retrieve -o FASA:/fcp_dw/vmfs_vol1 -C LUN:avg_latency -b "2012-01-05 16:30:00" -e "2012-01-06 09:30:00" -s 60 >> avg_latency.txt
