Thanks Karl. Unfortunately that didn't work either. Here is an example of my actual data:

02222013083723,ServerA,586950936,1709,20817,3.510409

There is a script that goes out to different servers and grabs some metrics. It then sends the data to a metrics file. In the case above, there are four servers. The last data point (6) is the CPU utilization. My goal is to create one graph with the CPU utilization of all 4 servers on it. A line graph would be perfect here. 

This is what I use to plot ServerA CPU:
plot 'test.txt' using 1:(strcol(2) eq "ServerA"? $6:$1/0) 

To plot all 4 CPU's, I would use:

plot 'test.txt' using 1:(stringcolumn(2) eq "ServerA"? $6:1/0) title "ServerA"  ,\
'test.txt' using 1:(stringcolumn(2) eq "ServerB"? $6:1/0) title "ServerB"  ,\
'test.txt' using 1:(stringcolumn(2) eq "ServerC"? $6:1/0) title "ServerC"  ,\
'test.txt' using 1:(stringcolumn(2) eq "ServerC"? $6:1/0) title "ServerD"  


This would create a graph with an different color of 'X' for each data point. This is difficult to see when you start adding more servers. Being able to draw one line for each server CPU would be great. 

Is there any other way to do this? The plot command I used above is basically taken from an older post in a support group to plot filtered data. Maybe with Gnuplot 4.6, there is a different way to do this?


If you want to plot the data above yourself, use these parameters:

set xdata time
set format x "%H:%M"
set timefmt x  "%m%d%Y%H%M%S"
set datafile separator ","
