I would like to take the top 10 processes by % CPU usage over contiguous
60 second intervals of and record it to a file in a format that is
amenable to post processing.

The command "topas -Pi 60" has the information I want but its formatted
with terminal escape sequences which make it difficult to process later.

Taking periodic samples with "ps aux" and sorting on %CPU is almost
there, but its on a sample basis which is not over the whole 60 second
period.

Does anyone have any solutions or better ideas?

TIA & Regards,

Alex.

NMON and NMON Analyzer
Free tool from IBM (and a good one IMHO)

Thanks...

Had seen NMON, but looks like another curses type terminal based output
.... does it provide file based output as well?

Alex

aha ... I see the statment "The nmon tool can also capture the same data
to a text file for later analysis and graphing for reports. The output
is in a spreadsheet format (.csv)." on the page you ref'd

Ta,

Alex.
