<DIV>Hello,<BR><BR>I've been tasked with creating a monitor that can check list of URLs,<BR>and send e-mail messages when one is unreachable or contains errors. <BR>Handling the monitoring part of this task is very straightforward.<BR><BR>However, one issue I've run into is that the machine that monitors the<BR>URLs may see the URL as down due to a local network connectivity<BR>issue, when in fact the URL is accessable to other machines located<BR>elsewhere on the Internet. What I'd like to do is use Spread (or<BR>something similar) to create a private peer-to-peer network of<BR>monitors that, when one machine sees a URL down, checks with its peers<BR>and sends an e-mail only when all peers see the same URL as being<BR>down.<BR><BR>Do you think that Spread is the correct tool for this? Being a newbie<BR>to Spread, I'm not sure if it would be capable of doing what I need it<BR>to.<BR><BR>As it stands, the monitoring part of this script is written in Perl,<BR>and I'd like
to continue to use it for the messaging part of this<BR>task.<BR><BR>Any help/code samples would be greatly appreciated!<BR><BR>Thanks,<BR><BR>Mike<BR><BR></DIV><p>__________________________________________________<br>Do You Yahoo!?<br>Tired of spam?
