Symptoms

Accelerate analysis of isi statistics performance data, by graphing it visually.

Cause

Working with performance numbers can be difficult to sift through and analyze.

Resolution

  1. Gather Performance data, use the --noconversion and the --.csv switches commands.
Example:
# isi statistics drive --noconversion --csv --nodes=1 --degraded

Note: If the data was not gathered as .csv (Comma-Separated Values) it can be converted to .csv, or import with a different delimiter. Here is an example of how to convert it:
# while  $file;do echo "Please enter the full path to the file.";read file;done;echo "Processing "$file".";awk 'NF >0' $file|sed -e 's/ \+ /,/g' -e 's/\ /,/g'|cut -c 2-|tee $file.csv
This asks you to provide the path to the file, and it creates a copy with the same file name with .csv at the end.
 
  1. Once you have your data in a text file that has a .csv format, you can import it into Excel.
    1. In Excel, go to the Data tab
    2. Under Importing options, choose From Text.
    3. Find your file and select Import.
    4. Choose Delimited, press Next
    5. Choose Comma for the delimiter type.
    6. Select Finish
  1. Graph the dataset:
    1. It is recommended to remove the following line, or your graph is 1 off. 
LNN:bay,,N/s,B/s,N/s,B/s,ms,ms,,%
  1. Highlight your dataset.
 
Note: If you are working with multiple statistics, only highlight data of the same units. Otherwise, your graph is skewed.
 
  1. Go to the Insert tab.
  2. Select type of graph (Column, Line, or Scatter plot are good for most situations).
