Question

是否有任何工具/插件可以识别grails Web应用程序中每个请求的内存，cpu和其他使用信息等配置文件。

Answer 1

尝试一下：

public class CrunchifyJVMParameters {


    public static void main(String[] args) {

        int mb = 1024 * 1024; 

        // get Runtime instance
        Runtime instance = Runtime.getRuntime();

        System.out.println("***** Heap utilization statistics [MB] *****\n");

        // available memory
        System.out.println("Total Memory: " + instance.totalMemory() / mb);

        // free memory
        System.out.println("Free Memory: " + instance.freeMemory() / mb);

        // used memory
        System.out.println("Used Memory: "
                + (instance.totalMemory() - instance.freeMemory()) / mb);

        // Maximum available memory
        System.out.println("Max Memory: " + instance.maxMemory() / mb);
    }
}
