LoadRunner监控Linux的三种方法

方法一、LR + SiteScope/nmon

 

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：
