EJ Technologies Perfino 是一款JVM监测工具，旨在为您提供监控多个Java虚拟机之间的活动和交互的方法，让您深入了解其性能及其错误，此外软件还提供数据分析技术。无论您的系统有多大，或者您希望监控多少微服务，您的perfino都可以满足您的要求

perfino是JVM的监控工具。它旨在用于生产中和 为受监视的应用程序增加了极低的开销。其操作模式的特点是APM，短 用于应用程序性能管理。而不是在低级别收集性能数据，并且 Perfino 的范围很广，在高语义级别呈现选定的操作，称为业务事务。 此外，标量数据从各种来源进行监控。根据该数据，阈值违规 可以生成警报，帮助您保护应用程序的服务质量。

Perfino 旨在始终与您的应用程序一起运行。这使它能够专注于历史数据，向您展示性能特征在很长一段时间内如何演变。 随着时间的推移，数据会自动变得不那么精细，因此您只需回顾过去 存储空间消耗速度慢。

perfino 旨在监视多个 VM 并跟踪它们之间的交互。是否 拥有多个固定虚拟机安装或具有数百个虚拟机的云部署，perfino 可以监控和 同时组织它们。

perfino UI是一个Web界面，可供多个用户用来分析收集的数据 与此同时。访问级别系统允许您为多个组对单个服务器进行分区。

Perfino is a highly complex piece of software designed to offer you the means of monitoring the activity and interactions between multiple Java Virtual Machines, providing you with insight into their performance, as well as their errors.

MICRO-SERVICE FRIENDLY LICENSING
One license to monitor them all: With perfino you don't have a cap on the number of monitored JVMs or any other metric, such as recorded business transactions.
No matter how large your system gets or how many micro-services you want to monitor, your perfino license has you covered.

IMMEDIATELY SEE WHAT'S WRONG
When you log into perfino, the dashboard shows you if everything is OK - or if something is going wrong. perfino gives you fine-grained control over what level of performance is acceptable for your application. The dashboard is where you start to drill down into the more detailed data views.

SHOW CALLS BETWEEN VMS
perfino can monitor business transactions that span multiple VMs. A call in the web layer that goes on to an EJB server and further to a web service - in perfino these operations are connected, even when you do method-level sampling. The call graph not only shows you the big picture of what is happening right now, but also what has happened in the past.
