Shell Programming and Scripting

Hello Guys,

I am starting with shell scripting and I need some help with my problem... The scenario is, I have like 20 servers inside one company, where I face some network issues affecting my servers functionality (Voice/recorder/IVR systems). So, to evidence the network events, I decided to code one script simple to monitor the ping events.

Here is the code:
-------------------------------------------------------------------------

Code:

#!/bin/bash
ping HOST | while read pong; do echo "$(date): $pong"; done >> out.txt

-------------------------------------------------------------------------

It's simple, but worked fine... the problem is... I need to improve this, I need to print the results with names and archive it (.tar.gz) each 24 hours, and keep it for only 15 days, also ping multiple hosts simmultaneously. The name has to be date.IP.tar.gz.
Another important point is that it does not save the timout intervals, so I will just have an interval with no data... and I need to evidence that.

Any help ?

So do you mean that you want you output file to have a date in it, e.g. for today you want the file to be out_2014_05_06.txt so you can then (at the end of each month) collect up all of out_2014_05-*.txt and create an out_2014_05.tar.gz ?

Is that it? Forgetting the ping/pong bit and this is all about log file management. Is that correct?

If so:-Most importantly, what have you tried so far?

Going back to the ping/pong one line of code, how would you expect this to end? on unix, the ping usually continues until interrupted, not like on DOS/Windoze.

You will need to check that manual pages for ping to check the flags to set a limit. It may be -n, -c or something else on your OS. You may have heard that unix is all the same, but at out level, they're all different.
