hi,
we have written some monitoring scripts for network connectivity. We use send 4 ping packets and check the avilability of connectivity.
But 2/3 times, it was dicovered that it gives a false alarm when everything is fine! Is it possible that ping get lower priority when the network is under heavy utilization? Is there any other way to do this in more reliable fashion.
please advice ... thanks in advance
What's your alert/escalation logic? Does the script generate an alert after just one failure or does it retest?
The most common problem in situations like these is that by the time you react on the alert generated a script/system, the problem might have gone away.
Suggest Nagios like SR, since you can build quite sophisticated alert logic. Also suggest using SmokePing to graph the results of pings.
