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

Hello All, Here's my question: I'm trying to ping about 1500 to 2000 machines in our environment, but instead of having 1 system command pinging each machine, I'd like to have 4 or even 8 system commands running simultaneously, which can decrease the amount of time to ping all the machine significantly. Is this possible through perl?

    With perl 5.8's new iThreads you could easily write up a quick multi-threaded script that could use X amount of threads, each one pinging a machine. For more info, check out the perlthrtut.

    However, this is obviously for tracking servers/machines remotely to make sure they are still alive, in which case, this wheel has been invented many times before, and much better than it could be written by a single person in any usable time frame.

    Windows: What's Up Gold works pretty well, very graphical and boss-friendly (ooo, pictures!).

    *nix: There are several, I have used both NOCOL and Big Brother. Choose whichever one works best for your needs.

    Sounds like a job for fping.

    What type of environment is this and what 'bookkeeping' are you looking to do with the results from ping? There are much better solutions for availability monitors.
