aladdin123 has asked for the wisdom of the Perl Monks concerning the following question:

After searching around CPAN and PerlMonk, I can hardly find some matching answer of my network monitoring requirements.

There are 500 machines, we need to "PING" (or ICMP packet sending and receiving) from one node to every other node, in a very short interval (like 1 second).

So we need to fire a bunch of ICMP packets simultaneously to 499 servers, and receive response within a timeout period (like 1 second).

Gurus please advise some possible programming methods, which can do this "continuously" network monitor.

Thanks!

      nmap even has XML output, and there is Nmap::Parser, which consumes the output of nmap and provides it as a Perl data structure.

    You might also want to consider the (not uncommon) case where enough of the networking stack is still working that the host will respond to ICMP, but it's still non-functional. Monitoring the "upness" of a host is non-trivial. I ended up doing asynchronous SNMP queries for uptime as this also told me if the host had rebooted since last time I asked.
