processcsv.py

PROCESSCSV.PY(1)					      Virtualization Support						  PROCESSCSV.PY(1)

NAME

       processcsv.py - process virt-top CSV files

SUMMARY

	virt-top --csv data.csv
	processcsv.py < data.csv

DESCRIPTION

       virt-top is a top(1)-like utility for showing stats of virtualized domains.

       processcsv.py is a simple Python script that post-processes the output of "virt-top --csv".

       It is used like this:

	virt-top --csv data.csv
	processcsv.py < data.csv

       The second command will overwrite the following files in the current directory:

       "global.csv"
	   This contains the global (host) statistics columns from the CSV file.

       "domainNN.csv" (multiple files)
	   For each libvirt domain ID NN, a file is created containing the per-domain statistics from the CSV file.
