System optimization is a complex, complex, and long-term task. monitoring, collection, testing, and evaluation are required before optimization. After optimization, testing, collection, evaluation, and monitoring are also required, it is also a long-term and continuous process. It is not to say that the optimization is now done, the test is done, and it can be done once and for all in the future. It is not
Brief introduction
Many Java applications today rely on a complex set of distributed dependencies and moving parts. Many external factors can have an impact on the performance and availability of your application. These effects are largely not completely eliminated or resolved, and are difficult to simulate accurately in a prebuilt environment. Stuff happens. However, you can create and maintain a comprehensive system to monitor the entire ecosystem of your application, thereby significantly re

Listen ("tcp", addr), which is the bottom layer, builds a service with the TCP protocol and then monitors the ports we set up.The following code from Go HTTP package source code, through the following code we can see the entire HTTP processing process:Func

Monitoring of processes and ports can be monitored using Zabbix's own key, which is only maintained on the server side, which is simpler than the way Nagios uses plugins to monitor.

Golang's package management has been without an official unified solution, and therefore has produced many unofficial package management tools.
