Introduction to Linux Monitoring platformZabbix Monitoring IntroductionZabbix He is also C/s architecture, there is a server and then go to the client to catch data, grasping data in the client must have a service to start, the service is to replicate the data collected, this data can be actively escalated to the service side, can also let the service side to connect the customer to capture this data, which
Then we manage the server when the WINDOSW system is more intuitive, how much CPU use, how much bandwidth memory used, etc. as long as in the Remote Desktop Task Manager at a glance. But in the Linux environment is not so easy, especially the server or VPS running is a large web site, if you can not find the server performance consumption in time, it is likely to lead to the site in the peak visit, there is no known card death. So, eagle, then. This article describes how to use SNMP plus
In parts 1th and 2nd of this series (a total of three articles), I introduced the techniques and patterns for monitoring Java applications, in which I focused on the JVM and application classes. In this final installment, I'll introduce tips for collecting performance and availability data from application dependencies, such as the underlying operating system, the network, or the application's back-end database. At the end of the article I'll discuss
What does a surveillance system need to monitor?From the granularity, from small to large can be listed: one or two lines of code, a method, a service interface, a service call chain, an application service (application port, JVM CPU and memory consumption, etc.), hardware (CPU, network card, hard disk, etc.).The monitoring of the method can be extended to the monitoring of the HTTP link/connection pool, th

Methods for LAN wireless routers to limit network speed, wireless LAN traffic monitoring, and lan network speed monitoringAt present, many organizations use wireless routers to access the Internet. Although network access is convenient, the network of mobile devices such as mobile phones and tablets makes it difficult for many network administrators to defend against attacks. Therefore, we need to limit the network speed of the wireless LAN to prevent

With the upgrade of Mobile Networks: 2G-> 3G-> 4G, or even 5G under development, the network speed is getting faster and faster, but the traffic is also like a flow of water.
The Internet does not spread a story: if you forget to turn off traffic during sleep, the house will be moved the next day!
This is an exaggerated state
In addition to the ps command or query port, the Process status can be confirmed by checking related logs. If the process log settings are reasonable, the log file should contain the process information, including the processed data and exceptions. Because the log file is written, the log timestamp is updated accordingly. By monitoring whether the log file is refreshed, you can check whether the process has any errors, such as process suspension and c
