So, you require this output using another method? Or do you need something else? Can you please explain what you need.

Also we need to see sample output of rrdtool to help you at all.

Yes, I want this output using shellscript and detect over limit defined in script and send warning mail.

The script has to deal with the traffic values of input and output for Mbps / s

Sample outprint from rrdtool fetch is:

Code:
[172]> rrdtool fetch /usr/local/cacti/rra/gw1_gc_traffic_in_284.rrd AVERAGE -r 300 -s -1h 
                     traffic_in         traffic_out

Since it look like maybe you have cacti you might want to invetigate the "theold" plugin for cacti. Then you can easily setup alerts from cacti for things. If that's what you want.

I'm just taking a guess and trying (maybe) to get you to your solution in a better/faster way (?)

Exact is the best solution, but I do not have admin access cacti in my work and I will not have

My boss said if I could create a script to do this by rrdtool

The only way would be to create this script, to read the file, set a limit on mbps, calculate the maximum limit and warn you if you exceed.

Thanks for the tip, but I need to find a way to learn and do this.
