从LR里面add measurement,填写linux机器的IP,出现所有unix/linux的计数器,包括cpu的,mem的,disk,network的。这里介绍几个常用的:
average load :在过去的1分钟的平均负载
cpu utilization: cpu的使用率
disk traffic: disk传输率
paging rate:每秒从磁盘读到物理内存,或者从物理内存写到页面文件的内存页数
Swap-in rate:每秒交换到内存的进程数
Swap-out rate:每秒从内存交换出来的进程
如果发现服务器重启后不能监控了,可以手动重启rpc.rstatd。

Average load:
Average number of processes simultaneously in Ready state during thelast minute
