Ping is a network command that is primarily used to determine if a local host can exchange (send and receive) data with another host.
Based on the information returned, it can be inferred that the TCP/IP parameters are set correctly and are functioning properly.
Under normal circumstances, Ping will return several parameters with a loss rate of 0.
When the network status is poor or the network is interrupted, the Ping operation will not return the TTL parameter (display request timeout or other bugs).
The ping operation can be easily performed through the ms-dos of the Windows platform.
However, this operation can simply test whether the network is normally connected, and generally eliminates the faults of the network access layer, the network card, the MODEM input and output lines, cables, and routers.
I want to know more about the connection speed and connection time of the website, get detailed information about the connection error, and need to pass specific monitoring tools.
The Super Ping tool is a set of tools for real-time monitoring of multiple host network status, analysis of monitoring results, network shutdown alarms, and network status reporting.
The ICMP protocol is used to monitor the status of the host network.
It has the following characteristics:
- Network monitoring based on ICMP protocol.
- Support two network monitoring modes: continuous monitoring and interval monitoring.
- Provide various network anomaly alarm methods such as SMS and email.
- Multiple hosts can be monitored at the same time.
Ping monitoring usage scenarios
To understand the usage scenarios of Ping monitoring, we have to introduce several indicators of Ping monitoring.
Availability
Availability is the probability that the system will function properly or the expected time share at a certain time. It is a measure of the actual performance of the system after it is put into use, and is a comprehensive feature of the reliability, maintainability and maintenance support of the equipment or system.
From the user’s point of view, it is the quality of the product perceived by the user, whether the system is stable and whether the service is available. Usability considerations are important in web monitoring.
Good availability ensures that the system is functioning properly, and users don’t have to be distracted by operational issues and focus on tasks. For example, for e-commerce websites, its usability is reflected in three aspects: effectiveness, efficiency, and user satisfaction (Satisfaction).
Websites with poor usability may collapse at a certain point, such as payment. Link, which will have a devastating effect on the user experience. For example, if a website with poor usability cannot find the product on the Internet, they will not be able to make a purchase, and the website will lose potential sales.
Ping monitoring can provide specific parameters of availability indicators, monitor system availability in real time, and monitor from different dimensions such as operators and provinces to fully grasp the available performance of the website.
Response time
In the operating system, response time refers to the time when a user makes a request or an instruction to the system to respond (response).
For the user, when the user clicks a button, issues an instruction or clicks a link on the web page, the user clicks on the application to display the result of the operation in a user-perceivable manner.
The time spent is a visual impression of the user’s performance. Response time has a direct impact on the user experience.
If the system response time is too long, the user will feel uneasy and frustrated, and the short response time will sometimes cause the user to speed up the operation and cause errors.
For example,
Asystem has an information query function. When you enter a conditional query, you may need to query millions of data. If the database wants to query all the data to search for the information I need, the server may have to query for a long time.
The time consumed by the process will cause a certain load on the system and the user. How to properly grasp the length of the response time is also a problem that the website builder needs to consider. Ping monitoring not only monitors network connectivity but also visually reflects system response times:
Packet loss rate
The packet loss rate is the ratio of the number of lost packets in the test to the transmitted data set.
The high packet loss rate will have a serious impact on the system. In the case of games, the TCP protocol can only wait for retransmissions when it drops a packet, which seriously affects the network speed, causing picture jams and frame skipping, greatly extending the waiting time and greatly affecting users experience.
The causes of network packet loss include physical line faults, equipment faults, virus attacks, and routing information errors. Among them, line equipment faults and network congestion are the main causes of packet loss.
The specific reasons may be improper software configuration or hardware device failure. It is signal interference, etc., which must be analyzed by specific monitoring tools.
Ping monitoring can provide specific parameters of the packet loss rate and provide specific error information to help the operation and maintenance personnel to properly repair and improve system performance.
