After installing the COLLECTD tool on the host, you can obtain data such as cpu,memery,if-traffic of the virtual machine on the host by using the COLLECTD tool. Monitoring of these data can be achieved through Nagios monitoring scripts.The following is a simple monitoring virtual machine memory script:#!/bin/bash#desc:

The check_antp provided by nagios is too simple. In addition to the status statistics output, no parameters are provided. When faced with different application servers, alarm becomes a big problem.So I decided to write a check script myself. When running a script, it is different from the command operation, that is, to consider the efficiency issue. Running the netstat-ant command regularly on high-concurrency machines for statistics is obviously not
