捕获集群的性能
我有一个包含 10 个节点的集群，所有节点都有类似的操作系统（ubuntu 10.4）。我想监控每个节点的性能，基本上捕获给定时间的 cpu、内存等。我如何在每个节点捕获相同的数据并对结果进行聚合以获得组合结果 例如整个集群的平均 CPU 使用率。
有什么命令我可以运行并获取结果吗？
提前致谢。
I am having a cluster containing 10 nodes all of which have similar operating system(ubuntu 10.4).I want to monitor the performance of each node basically capturing the cpu ,memory etc at a given time.How can i capture the same at each node and aggregate the result to get a combined result Example the average CPU usage of the entire cluster.
Are there any command I can run and get the results.
Thanks in Advance.

您可以使用 pbsnodes 命令的输出来捕获此信息。如果查看状态：
status = rectime = 1319751989，varattr =，jobs =，state = free，netload = 904408724，gres =，loadave = 0.63，ncpus = 6，physmem = 8193856kb，availmem = 14823060kb，totmem = 16581436kb，空闲时间= 362，nusers = 1，nsessions = 15，会话= 1788 1171 19146 19183 19197 19207 19217 19282 19329 19553 19617 20238 20292 20535 20601，uname = Linux napali 2.6 .38-12-generic #51-Ubuntu SMP 2014 年 9 月 28 日星期三:27:32 UTC 2011 x86_64,opsys=linux
您可以在那里看到它具有计算机的平均负载，以及有关机器内存状态的几条信息。通过编写一些解析执行您正在寻找的计算的脚本，您可以解决您的问题。
You can use the output of the pbsnodes command to capture this information. If you look at the status:
status = rectime=1319751989,varattr=,jobs=,state=free,netload=904408724,gres=,loadave=0.63,ncpus=6,physmem=8193856kb,availmem=14823060kb,totmem=16581436kb,idletime=362,nusers=1,nsessions=15,sessions=1788 1171 19146 19183 19197 19207 19217 19282 19329 19553 19617 20238 20292 20535 20601,uname=Linux napali 2.6.38-12-generic #51-Ubuntu SMP Wed Sep 28 14:27:32 UTC 2011 x86_64,opsys=linux
You can see there that it has the load average for the computer, as well as several pieces of information about the memory state of the machine. By writing some script that parses that are performs the calculations you're looking for, you can solve your problem.
