YMU-Node as the monitoring point in YMU "Neighborhood Watch" network is the basic element. YMU-Node receives monitor tasks from YMU control center, execute these tasks, and then return the result to YMU data center.

• 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;

• 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.

• 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;

We provide the demo show to help you to use our monitoring service, you can view it by visit our homepage or enter into "How to Start" page. There are five demos: one is global, other four are detail function guides:

YouMonitor.us gives you 30-day trial experience that you can access and utilize all services but need not to contribute an YMU-Node.After 30 days, to continue enjoying YMU monitor services you need to contribute YMU-Node to the peer to peer network.

To become a member, go to our home page and click "Register". Once registered, your 30-day trial experience will begin immediately. During that time you'll have full access to all system services and functions, just as if you already contributed an YMU-Node. When you login to YMU system first time, YMU wizard will guide you to customize monitor service for your website step by step. Or, you can customize monitor service by "Services" item of "My Control Center" menu.See demo show by click here.

A Transaction can be thought as a serial sub monitor tasks (these tasks must be execute by orders) combine to a total monitor task: if the serial monitor tasks are use HTTP protocol, the transaction is a HTTP Transaction.

User can set a serial of http pages as a transaction: YMU service will monitor the serial of http pages by orders, then report a total response and downtime of the transaction.

Yes, you can test HTTP, HTTPS or HTTP Transaction monitoring tasks freely. For a HTTP Transaction task, the total step count can be up to 10.

Monitoring interval is how often your website will be checked. You can define the monitoring interval from one minute to an hour; but for a HTTP Transaction task, the lowest monitoring interval is 5 minutes.

Monitoring source means the number of locations your site is being checked. We currently have over a hundred monitoring sources around the world. The source can be from continents to countries to states, and you can select the source from which you want your website monitored. For a monitoring task, the max number of monitoring source is 10.For select monitoring source, we not only support key search in map, but also support direct locate in map.

Yes, you can define the he number of monitoring tasks you want to according to your YMU Points.

You'll get 300 YMU Points if contribute a YMU-Node; according to your YMU Points, you can free configure monitoring interval, the number of monitoring source and the number of monitoring tasks;

Yes, Login to the YMU system, enter into "My Control Center" and click "Suspend" in "YMU-Node" or "Services pages" to temporarily stop outbound or inbound monitoring and "Resume" to start monitoring again. But, if you suspend a YMU-Node, you will lose related YMU Points for your website after 30-day trial experience.

The only difference exists in the number of checks. All other features that are presented in advanced package are also offered in standard package.

Checks used on each service are the multiplying result of monitoring source and how many times the monitored website is monitored. For example, if you choose 4 monitoring sources and the monitoring interval is 1 minute, then the checks used is 4×（60/30）= 8.

The first month is counted from the date your 30-day free trial finishes to the same date next month. Each following 30 days is defined as a month.

60 extra checks are available at $4.99 for a month.

Extra SMS are available at $ 0.2 each. The fees will be billed to you.

You can choose to unsubscribe at any time. Whole refund or partial refund would be available. Please read more on Fees Policy.

Yes. You can configure alert rules for parameters such as response time,availability percentage,and others. You can customize alert settings for all monitoring tasks by Alert menu, and also local alert setting for a single monitoring task.

For the monitoring tasks assigned the by customer, the global alert settings would be set by default if they have not configured them specifically.

For a monitoring service's report, we not only provide statistical data for all its specified monitoring sources; but also provide detail data for every specified monitoring source.

As the statistical data charts, we provide the compared availability percentage and response time for your site from all sources.By these charts, you can know where access your site is fast and high uptime.

As the detail data charts, for every monitoring source, we provide performance chart give response times or lag time accessing, availability chart show downtime instances, alert chart give you alerts settings on your website.

Yes. We provide two types operation modes for you: Basic and Advanced modes, and you are free to switch between them as much as u like.

The basic mode allows you to select the most common and default options for quick and easy setup.

Dedicated probes represent costly capital investments, and a single probe can't give you a complete picture about your website's global reach. If you want to enjoy the service must paying costly to these companies.

YMU "neighborhood watch" network, customers not only receive detailed web-service monitoring from all over the world,but participate in the low-bandwidth, highly-secure monitoring tests of other participants in the peer to peer network. Our massively-distributed peer to peer infrastructure means that the expansion of monitoring areas and regions is essentially unlimited, All participants have unparalleled monitoring coverage and a near perfect view of how their website services appear to customers all over the world.
