After determining the need for demand, then talk about the basic requirements of online monitoring. The so-called basic requirements are certain to meet the requirements, less than these basic requirements of online monitoring services is not perfect and inconvenient to use.

1. Easy to use

Webmasters are not familiar with the network technology, so the use and configuration of the threshold can not be too high, too complex configuration will let people lose the use of interest. Should have to apply for domain name space, build the basic technical background of the station is not much trouble.

2, the function must be complete, the parameter configuration should be fine

Everyone's requirements are different, some people just need to know when the failure, and some people are very interested in monitoring reports. This is a little contradictory to the "easy to use", simple and difficult to complete, a lot of parameter configuration brings the complexity of use. A better solution is to use the wizard-style configuration, step-by-step prompts to operate, the configured parameters to use the default value, can be modified freely. Can be used immediately in the simplest way, and then configure the parameters in detail according to the actual needs.

3, Automatic online 7x24-hour monitoring

This is, of course, the most basic requirement, and it's a joke that online monitoring services are much lower online than your website.

4. High frequency of monitoring

Online monitoring has a collection frequency, such as 1 minutes to collect data, the higher the frequency of acquisition, the shorter the alarm time. Acquisition frequency can not be too short, such as a more than 10-minute acquisition frequency loss of monitoring significance (perhaps this time the so-called automatic alarm is slower than artificial alarm). But online monitoring cannot be a service for you, and it is generally a simultaneous monitoring of thousands of surveillance targets. Monitoring frequency in 1-2 minutes has satisfied most of the webmaster and network management requirements.

5, can get the warning message as soon as possible

Automatic monitoring to the failure occurs, you need to receive the warning message as soon as possible. There are several commonly used methods of receiving alarms:

(1) The advantage of the message is universal face, use free, accept speed, message details; The disadvantage is that you need to take the initiative or receive the message on a regular basis, the effectiveness of the poor.

(2) SMS advantage is that as long as there is a mobile phone, no matter when and where all can be informed of the alarm notice; The disadvantage is that most of the text message needs to be charged, SMS is generally 1 cents, but the fault will not always occur, so the cost will not be too much. It is worthwhile to buy more time to solve the problem.

(3) The advantage of the telephone is the most real-time, you may ignore the warning message, but the voice of the telephone ringing most of the time you will always pay attention to; The disadvantage is that the telephone automatic alarm technology is relatively difficult, the cost is relatively high.

Can be based on the actual needs of the combination of alarm mode, not too important to receive the alarm with the message, the important alarm with the message received, very important alarm by telephone way to receive. And the need for different monitoring objects sent to different alarm recipients, such as network disconnection need to be sent to network management, server when the machine needs to be sent to the server administrator, the site will not open to send to the webmaster and so on.

6, can provide active monitoring mode

The so-called active monitoring means that you do not need to install any code program on the website, the server, online monitoring automatic simulation manual access to monitor. Several commonly used monitoring methods:

Reference Ping Ping can check whether the server is networked and accessible, if the ping does not indicate that the server is disconnected or when the machine.

(2) Visit the Web page to simulate IE browser open the Web site, which is the monitoring of the return of 200 status, the contents of the Web page is incorrect, whether the Web page has been modified. Monitoring the Web site to monitor the normal access.

(3) Socket port connection UDP socket port is normal, such as Web page with 80 ports, FTP with 21 port, SMTP 25 ports, etc., such as monitoring to 80 ports can not connect, indicating that the server's Web service is not normal, the server's entire Web site can not access.

(4) Other can monitor FTP service, SMTP service, DNS service, etc.

Proactive monitoring because there is no need to install any code and programs, it is appropriate to monitor all Web sites and servers without worrying about security issues caused by installation code and programs.

7, can prevent false positives

To be sure that there is a problem before the alarm, there are killing the wrong alarm looks like no slip through, but the real alarm will drown in the false alarm, the consequences can refer to fairy tales "wolf".

8, to control the number of alarms

If the failure is not immediately resolved, a steady stream of alerts will be annoying. Imagine a few hours of constant receiving the taste of the alarm, to be able to send a certain number of alarms to suspend the alarm until the repair returned to normal.

9, can have detailed statistical report

Daily Online rate statistics, fault time statistics, monitoring performance statistics, alarm statistics, etc., these for you to evaluate the network, server stability has an important role.

10, free to use

This is the Webmaster network management are most important, most of the online monitoring services have a free version, to meet the most basic requirements.
