Extracting ICMP Output for Plotting

Paris Heng · 02-03-2008, 11:29 PM

Dear,

I want to perform a plotting using xgraph, and the plotting data (ping.txt) is as below. For the graph I just want to plot the time for x-axis (line count) and the RTT for y-axis (time in ms). Below are script i write for that purpose but it seen did not work. Any guide for me because i think the script is wrong. The plot is about like this,

Ping Plot Example

ping.txt
-------------------------------------------------------------
64 bytes from 192.168.1.100: icmp_seq=0 ttl=255 time=0.712 ms
64 bytes from 192.168.1.100: icmp_seq=1 ttl=255 time=0.620 ms
64 bytes from 192.168.1.100: icmp_seq=2 ttl=255 time=0.698 ms
64 bytes from 192.168.1.100: icmp_seq=3 ttl=255 time=0.662 ms
64 bytes from 192.168.1.100: icmp_seq=4 ttl=255 time=0.649 ms
-------------------------------------------------------------

Quote:

#!/bin/sh
#For x-axis (Time)
wc -l ping.txt > plot.txt

#For y-axis (RTT)
ping.txt | awk '{print $7}' > plot.txt

#Plotting graph using xgraph
xgraph -bb -tk -x "Time" -y "RTT" plot.txt

Intended plot.txt
-----------------
1 0.712
2 0.620
3 0.698
4 0.662
5 0.649

Does this get you closer to what you want?

Code:

#!/bin/sh
#For x-axis (Time)
wc -l ping.txt > plot.txt

#For y-axis (RTT)
cat ping.txt | awk '{print $8}' | awk 'FS="=" {print $1}' > plot.txt

#Plotting graph using xgraph
xgraph -bb -tk -x "Time" -y "RTT" plot.txt
