I don't see why you can't do that with POE.

If you have other processing to do once in a while just add it as an event in your main POE processing daemon (which is fo example tailling a log file up to now) and fire it up as often as you wish.

Then it will hopefully take full advantage of POE's cooperative behaviour.

Honestly implementing POE is an effort (small) but as long as you build the daemon from scratch I think it's a good choice (and you don't need cron jobs..).

Anyway there is more then one way to tail a log file :)

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
