Can you save and replay historical data in performance Advisor

wallindustry — Thu, 05 Jun 2025 07:23:43 GMT

Is there a methodology that would allow you to save a given amount of DFM data and then open it later analyses and comparison using Performance Advisor ?

Hi Keith,

Most of the data you see in Performance Advisor is saved on the dfm

server machine and can always be opened later for analysis.

The only data that is not saved is data shown in real time views.

I understand there is some historical data available in DFM but I'm looking for something similar to a trace file I could load for later analyses.

We don't have support to load data for analysis later.

Use the dfm perf data retrive to get the historical data.

dfm perf counter list only list the available counter for an object type.

Also use the dfm perf data describe to see how long is the data stored for each counter group.

dfm perf counter list shown default counter for PA which i am interested in "CPU Basics"

dfm perf view retrieve -a abc "Top CPUs" "2009-12-01 00:00:00" "2009-12-31 00:00:00"

Keith,

Also please note that you have queried for perf data from "2009-12-01 00:00:00" to "2009-12-31 00:00:00" while the data available from "2010-01-0416:14-27" (Mon Jan 4 16:14:27 2010) to "2010-01-05 11:44:40" (Tue Jan 5 11:44:30 2010) only.

This is the reason why you are not able to view the data (using dfm perf data retrieve)

<<<< dfm perf data describe, onli gave me data when i start playing with PA but not data kept in DFM.

This is the expected behavior. This CLI shows the start and end time of the perf samples available with DFM. You cannot see the perf data before PA is enabled. You may use 'dfm perf data modify' CLI to tune the default collection period and rate for the counter groups.

Oh i did it on purpose for the time range as i knew there would not be any data.

So, my next question is how to intepret DFM history data, it it dfm perf or some other cli i can use?

You may use 'dfm perf view retrieve' CLI to view the history data (if exists with DFM).
