• What is YMU-Node
  • If your website or web server participates in YMU monitoring network, the website or web server will become an YMU-Node in the network. How to participate? Download a tiny piece of open-source script and then installs into your web server just like publish a web page. After verified by YMU network, your website or web server becomes an YMU-Node in the YMU network.

    As an YMU-Node, it will receive monitor tasks from YMU control center, execute these tasks, and then return the result to YMU data center.

    For the tiny piece of open-source script, we provide popular web programming languages versions like

  • JSP/Jave/J2EE on Linux/Unix ( environment: Java 2 SDK 1.4 or higher, Servlet/JSP container which supports JCP's, Servlet 2.3 and JSP 1.2 );
  • PHP on Windows, Linux/Unix ( environment: Apache 2.0, PHP 4.3.9 or higher );
  • ASP on Windows ( environment: IIS web server (Windows 2000 server, Windows 2003), MSXML 4.0 Service Pack 2 );
  • Perl on Linux/Unix;

  • Security for Your Website
  • Installation of the open source script to your website is very secure. We've invested significant engineering resources to secure our customer's websites, so you don't need to worry about your website security. We'll use following several to guarantee after your site becomes an YMU-Node:
  • Authorization management ensures YMU-Node only accept monitor tasks from YMU control center. If the request is not routed from YMU control center, YMU-Node will drop it and abort immediately. The authorization prevents malicious hack attack.
  • DES algorithm to encrypt/decrypt the key information between YMU-Node and YMU control center; that prevents the interactive information be intercepted by the third party.

  • Resource Consumption Guarantee
  • You may be concerned with the amount of server resources that the YMU script is using during the monitoring of your site. We guarantee that the resource consumption is very minimal ( It will use about the same amount of resource as opening your websites homepage ).

  • For running the monitoring script 100 times in a minute, resource comsumption is as follows ( on a common server with Intel Pentium 4 3.06GHz CPU and 1G memory ):
  • Memory: 8.5M - 9.5M;
  • CPU: 2.0% - 3.0%;
  • Bandwidth: the comprehensive bandwidth is 200 B/s for HTTP monitoring and 2 KB/s for HTTP Transaction;

  • Don't worry about the resource cost and security for your website, if you join us. We provide an excellent monitoring task scheduling and security policies for your website view the "a Tiny Piece of Script Security White Paper" for details.
