LoadRunner监控Linux的三种方法
方法一、LR + SiteScope
方法二、使用rstatd包
1、下载rpc.rstatd-4.0.1.tar.gz
2、解压缩
tar -zxvf rpc.rstatd-4.0.1.tar.gz
3、配置
./configure
4、编译
make
5、安装
make install
6、启动
rpc.rstatd
7、在LoadRunner中添加计数器
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
8、将服务设置为自动启动（Linux启动时自动启动这些服务）：
vi /etc/rc.d/rc.local
如：
#rpc.rstatd--绝对路径
/usr/local/sbin/rpc.rstatd
方法3、使用Shell脚本
使用Shell脚本收集Linux资源写入csv文件，再通过LR的Analysis导入csv文件（Tools - Extenal Monitors - Import Data... ）
Shell脚本如下所示：
