in reply to [OT] Server Monitoring

There's several "stops working" scenarios you might want to look at.
  • httpd stops working.

    Use a cron job on the webserver to make sure an httpd process exists.

  • Database stop working.

    Use a cron job on the DB server to make sure the DB process is running.

  • The machine itself stops working.

    Use a cron job on some other machine to ping the server.

Cron jobs and Mail::Sendmail to your cellphone are all you really need.


  • In general, if you think something isn't in Perl, try it out, because it usually is. :-)
  • "What is the sound of Perl? Is it not the sound of a wall that people have stopped banging their heads against?"

    True. But i was kindof hoping there would be a ping service out there already.
      If it takes you more than 30 minutes to write these three scriptlets, I'd be shocked.

[1nickt]: Yaerox probably best to whip up an SSCCE demonstrating the failure in what you have now and post to SoPW as a question.
[Corion]: Yaerox: That's a somewhat hard problem. Encode solves the conversion part, but for guessing what encoding a file is in, that's the hard part
[Corion]: Yaerox: There is Encode::Guess, but that needs a limited set of inputs, and it also cannot handle multiple single-byte encodings
[Corion]: If you have a BOM, that's a really easy way to recognize UTF-8. Otherwise, you can try to decode a file from UTF-8, and if that works OK and doesn't crash, most likely the file was valid UTF-8
