步骤1: 创建 Spring Boot 项目 首先,你可以通过 Spring Initializr( Spring Boot 项目。选择相应的项目配置,建议使用 Maven 作为构建工具。确保选择 Spring Web 依赖。 你可以使用命令行创建项目: curl-ddependencies=web-dname=MemoryUsageDemo-dpackageName=com.example.memoryusagedemo-omemoryusagedemo.zipunzipmemory...

例如:监控系统系统中,保存某个服务器的cpu和内存等资源使用情况,使用cpu_usage_total 的表名(measurement)保存数据。以下表示某一个point的样例数据: 其中time为time字段,记录数据产生的时间;cpu_usage和memory_usage分别代表CPU使用率和内存使用率,因此他们是field字段,真正的监控数据;cpu 和host代表CPU的名字和服务器...

It has sometimes been suggested that Spring and Spring Boot are “heavyweight”, perhaps just because they allow apps to punch above their weight, providing a lot of features for not very much user code. In this article we concentrate on memory usage and ask if we can quantify the effect ...

当运行一个Spring Boot项目时,如果未设置JVM内存参数,Spring Boot默认会采用JVM自身默认的配置策略。在资源比较充足的情况下,开发者倒是不太用关心内存的设置。但一旦涉及到资源不足,JVM优化,那么就需要了解默认的JVM内存配置策略。 关于JVM内存最常见的设置为初始堆大小(-Xms)和最大堆内存(-Xmx)。很多人懒得去设置...
在Spring Boot 以及其他 Java 应用程序中,OutOfMemoryError 异常通常是由于 Java 虚拟机(JVM)中的堆内存耗尽造成的。防止 OutOfMemoryError 的关键是对内存管理进行优化和监控。 在Spring Boot 以及其他 Java 应用程序中,OutOfMemoryError 异常通常是由于 Java 虚拟机(JVM)中的堆内存耗尽造成的。防止 OutOfMemoryEr...
