You don't show us any code that produces the error message. If you assume that there is an error in your script, you will tell us what error message your script produces, and also what the script is supposed to do. If you assume that there is an error in your monitoring tool, you will need to show us that code instead of the other code.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
