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.
