Dear sir
Although at no of places many types awk files are available, but i am requesting you please give me awk script for packet loss and total throughput for my attached .tr file.I want to calculate throughput between node 4 and 0
There is a problem in attachment so please have a look some sample lines of tr file ....

Nobody will give you anything without you showing an attempt.

Dear sir
I had tried with no of script but not getting satisfactory output. With some script output is available but not mapped with trace file, with some script there is no output even manually i checked the codes. Please find the attached copy of script i have used....
regards
There is still some problem in attachment ....how can i share script i have used.

chrism01 · 09-10-2015, 12:56 AM

Just post the script, inside CODE tags see https://www.linuxquestions.org/quest...do=bbcode#code

Aabha · 09-10-2015, 03:53 AM

this is one of the script i have used

PHP Code:



BEGIN { 
bytes_recvd = 0; 
throughput = 0; 
interval = 1; 
current_time_instance = 0; 
 nxt_time_instance = current_time_instance + interval; 
} 
  { 
action = $1; 
time = $2; 
from = $3; 
to = $4; 
type = $5; 
pkt_size = $6; 
flow_id = $8; 
#src = $9; 
#dst = $10; 
sequence_n0 = $11; 
pkt_id = $12; 
 
if (time < nxt_time_instance) 
  { 
  if (action == "r") 
  { 
  bytes_recvd = bytes_recvd + pkt_size; 
  } 
  } 
else { 
current_time_instance = nxt_time_instance; 
nxt_time_instance += interval; 
throughput = bytes_recvd ; 
printf("%d %dn\n",current_time_instance, throughput); 
} 
}

@Aabha, please have a look at the <thr> scripts in "awk-and-perl_scripts_12.2014.tar.gz"
https://drive.google.com/file/d/0B7S...ew?usp=sharing
... One of the scripts may be usable for your particular ns2 trace file.
avg_throughput.awk
avg_throughput-zigbee.awk
avg_thr_wirelss.awk
chainThroughput.pl

.... If no success, you can read the files to get ideas for your awk code.

@Aabha : About `Attacments' :

All text files must have suffix .txt to be attached to an LQ post.

A (small) trace file can be attached as out.tr.txt : Please do not omit the .tr !

Larger files.tr(.txt) can be uploaded to 'Google Docs'.
Will be readable on-line with suffix .tr.txt .

Dear sir
Thank you for your prompt reply and guidance...

So hopefully one of the other scripts mentioned will help, but I thought I would shed some light on the one you were using.
After taking out any cruft which is not being used your script looks like:

Code:

#!/usr/bin/awk -f

BEGIN { 
  bytes_recvd = 0; 
  throughput = 0; 
  interval = 1; 
  current_time_instance = 0; 
  nxt_time_instance = current_time_instance + interval; 
} 
{ 
  action = $1;
  time = $2; 
  pkt_size = $6; 

  if (time < nxt_time_instance) 
  { 
    if (action == "r") 
    { 
      bytes_recvd = bytes_recvd + pkt_size; 
    } 
  } 
  else
  { 
    current_time_instance = nxt_time_instance; 
    nxt_time_instance += interval; 
    throughput = bytes_recvd ; 
    printf("d %dn\n",current_time_instance, throughput); 
  }
}

Essentially time is greater than nxt_time_instance for the first 11 rows and hence your output is:

Code:

After this it is greater than nxt_time_instance and hence the bytes_recvd is later added up but will never be displayed as the script has no way to get back into
the 'else' part of the script where the printf statement is generating output.

Hope that helps
