Full Discussion: script for continous ping
Operating Systems Linux Red Hat script for continous ping Post 302627311 by in2nix4life on Friday 20th of April 2012 12:01:09 PM

Morning.

Not sure what OS or shell you're running, but this may help:

Code:
while :;do date >> /tmp/monitor.log;ping -c1 <server> | awk '/packets/{if($4 ~ 0) print $0)' >> /tmp/monitor.log;echo >> /tmp/monitor.log;done

Output to log:
Fri Apr 20 11:56:36 EDT 2012
1 packets transmitted, 0 received, 100% packet loss, time 0ms

This one-liner will dump the current date and time to a log file, send a single ping to the server in question, and use awk to only print when there is no response to the ping. You can open another shell and tail -f the log file to watch it in real-time.

Hope this helps.
