获取 Yarn 应用程序的内存、CPU 和磁盘使用情况
Get the memory, CPU and disk usage for Yarn application
我想问一下在我 运行 一个 Yarn 应用程序之后，如何获得该应用程序的总内存和 CPU 使用情况。
我曾经使用资源管理器UI来获取所有信息。
但是除了从 UI 获取这些信息之外，还有什么
我可以用来获取信息的命令。
使用yarn application -status命令，您可以获得应用程序的Aggregate Resource Allocation。
例如当我键入 yarn application -status application_1452267331813_0009（对于我完成的申请之一）时，返回的行之一是：
Aggregate Resource Allocation : 46641 MB-seconds, 37 vcore-seconds
这会在几秒钟内给出聚合内存和 CPU 分配。您可以查看此答案：，以了解此输出的含义。
除此之外，截至目前，没有其他内存或 CPU 相关指标通过 CLI 公开。
命令 yarn top 给出了应用程序级别的资源利用率和经过的 运行 时间。
查看此线程以了解将输出通过管道传输到文件的方法
--帮助信息：
usage: yarn top
-cols Number of columns on the terminal
-delay The refresh delay(in seconds), default is 3 seconds
-help Print usage; for help while the tool is running press 'h' + Enter
-queues Comma separated list of queues to restrict applications
-rows Number of rows on the terminal
-types Comma separated list of types to restrict applications, case sensitive(though the display is lower case)
-users Comma separated list of users to restrict applications
'yarn top' is a tool to help cluster administrators understand cluster usage better.
Some notes about the implementation:
Fetching information for all the apps is an expensive call for the RM.
To prevent a performance degradation, the results are cached for 5 seconds,
irrespective of the delay value. Information about the NodeManager(s) and queue
utilization stats are fetched at the specified delay interval. Once we have a
better understanding of the performance impact, this might change.
Since the tool is implemented in Java, you must hit Enter for key presses to
be processed.
