As the saying goes, "Sen" needs to meet more advanced functional requirements when it meets basic requirements.

1, multiple locations and lines at the same time monitoring

Multiple monitoring sites are at the same time in different places on the site and server monitoring, such as in Guangzhou, Beijing, Chongqing and other points at the same time monitoring, any one point monitoring to the fault will be alarm. Multi-line refers to the use of different lines (telecommunications, unicom, railcom, etc.) at the same time monitoring. Location and line are combined to use, such as Guangzhou Telecom, Beijing Unicom and so on.

China's internet is artificially divided into North and south, the South mainly telecommunications, the North is mainly Unicom (formerly Netcom), there are other education network, railcom and so on. The speed of access to different network lines is slower and more unstable than that of the same network line, such as telecommunication access Unicom is a few times slower than telecommunications access to telecommunications, and occasionally there will be a situation of interconnection. The situation is more complicated with different locations. such as in Guangzhou ping Guangzhou Telecom is generally 10ms,ping Guangzhou unicom is generally 30ms,ping Beijing Telecom is the 20ms,ping Beijing Netcom is 60ms. In Guangzhou, we often monitor the Guangzhou Telecom line can not access the situation of the Guangzhou Unicom line.

Most webmasters and network administrators do not have the conditions to carry out multiple locations and line monitoring, online monitoring can easily help you solve this problem. If your website server is facing the whole country, need more locations and line monitoring.

2, fault alarm support main alarm and secondary alarm

Servers generally open a variety of services, such as Web services, mail services, FTP services, database services, network managers like to be able to monitor these services are normal. If you don't prioritize, when the server appears network failure or maintenance restart, you will immediately receive the site failure alarm, mail Service Alarm, FTP service alarm ..., even worse is this server can not recover when the short time, the alarm message sent to you, until the server back to normal or you crash.

For monitoring the service of the same server, it is necessary to define a main monitoring object, when the main monitoring object failure, only send the main monitoring object of the alarm, other minor monitoring objects suspended monitoring and alarm. For example, ping to do the main monitoring object, if the ping does not appear timeout, indicating that the server has been machine or disconnected, then only send the server ping alarm continuous monitoring ping, because the further monitoring and warning of other services have not been necessary. This can greatly reduce the number of alarm messages, and make monitoring more reasonable, more efficient.

3, custom alarm conditions

General monitoring to the results of success or failure, such as the ping impassability, access to the Web page error, not connected to the socket, which occurs when these are called failures, failure is the highest priority alarm. In addition, can also monitor the return delay, content, such as ping return delay, access to the Web page time, access to the content of the Web page. Using the results of the return can be customized alarm conditions, such as ping monitoring of the return delay is generally between 10-30ms, when the delay is greater than 100ms, indicating that the network or server may have problems, resulting in slow network response, need to immediately check whether the flow is too large or server CPU too high problem.

Custom alarm conditions can be more detailed monitoring content, accurate knowledge of the Web site and server status, before the failure to obtain more time to solve the problem.

4, custom Alarm message content

Alarm message content is very much, such as alarm site name, server IP, monitoring of the line, monitoring services, error information, occurrence time, custom alarm message content can freely choose to receive the alarm content, modified to fully fit their actual requirements. This point for the use of SMS to accept the alarm content is particularly meaningful, SMS content is up to 70 characters, in 70 characters fully know the fault content is more difficult, more need to be able to customize the content, adjusted to the limited character content can also know the fault time, fault content, such as: " 007 Movie Network 12:32 telecommunications line monitoring the first to 1 failures ", clearly know the fault information.

5, receive the summary report by the Mail

When the site and the server did not have much problem, we are lazy to log in to the online Monitoring service management background view. If you receive a daily summary report message from a Web server monitor, take a two or three-minute overview of the site and server status.

6. Passive monitoring

Although active monitoring can not require the installation of code and procedures, very safe and convenient, but lack of a lot of detailed monitoring content, such as the hard disk size, CPU usage, network traffic, etc., these monitoring content is very useful, such as the CPU is too high to indicate a site or program problems, traffic is too high to express the possibility of attack.

Passive monitoring is commonly used in SNMP (Simple Network Management Protocol), through SNMP to monitor most of the content you are interested in. Most operating systems support SNMP, which is very convenient and safe to operate. SNMP disadvantage is compared to occupy bandwidth, will consume a certain CPU and memory, in the CPU is too high and network traffic in large cases, can not effectively monitor.
