any website monitoring library/modules to use in my website?
<p>I'm trying to build a site which user can add their websites which should be monitored and can view a detailed report and statistics of it. And also it should be able to monitor local webservices (mainly),  </p>

<p>1) is there any popular java library to use for monitoring a website? (in sense to ping a website and load some content etc., or to show whether site is up or not kinda)  </p>

<p>2) Also to validate a flow of website (if possible)?<br>
Example: Go to login page, find fields , fill fields and submit form and validate for successful login or not.</p>

<p>I know this kinda looks big but any small part done can be helpful, I've found several of monitoring projects, but they only do normal websites but not local/other webservices and also they can't validate flow of website.</p>
