使用教程 linux下安裝rpc.rstatd 1.rpc服務需rsh的支持,一般情況下rsh已安裝。rpm -qa rsh查看。 2.右鍵另存為http://heanet.dl.sourceforge.net/sourceforge/rstatd/rpc.rstatd-4.0.1.tar.gz下載rpc.rstatd-4.0.1.tar.gz。 3.執行以下命令解壓和安裝 tar zxvf rpc.rstatd-4.0.1.tar.gz cd rpc.rstatd-4.0.1 ./configure //配置 make //編譯 make install //安裝 4.啟動 rpc.rstatd 如果第一次執行rpc.rstatd報錯,按以下步驟可解決報錯 cd /etc/init.d ./portmap start ./nfs start rpc.rstatd 5.檢驗,執行rpcinfo -p,看到以下信息表示安裝成功: 100001 5 udp 800 rstatd 100001 3 udp 800 rstatd 100001 2 udp 800 rstatd 100001 1 udp 800 rstatd 6.在LoadRunner中添加計數器 average load: 在過去的1分鐘的平均負載 cpu utilization: cpu的使用率 disk traffic: disk傳輸率 paging rate: 每秒從磁盤讀到物理內存,或者從物理內存寫到頁面文件的內存頁數 Swap-in rate: 每秒交換到內存的進程數 Swap-out rate: 每秒從內存交換出來的進程數 ......
