Loadrunner監控linux之詳解rstatd的安裝

1.    前期準備

 （1）把rstatd文件解壓到要監控的機器上。

 （2）打開終端，定位到rstatd文件夾下：查看文件夾中的內容以下：

[root@localhost rpc.rstatd]# ls

aclocal.m4    COPYING     Makefile.am    README        rstat_proc.c rup.1

config.h.in   CVS         Makefile.in    rpc.rstatd.8 rstat.x       rup.c

configure     INSTALL     missing        rstatd.8      rsysinfo.1    stamp-h.in

configure.in install-sh mkinstalldirs rstat_main.c rsysinfo.c

2.    執行步驟

（1） 執行：./configure 命令

[root@localhost rpc.rstatd]# ./configure

creating cache ./config.cache

checking for sys/ioctl.h... yes

checking for syslog.h... yes

checking whether time.h and sys/time.h may both be included... yes

checking whether gcc needs -traditional... no

checking for ANSI C header files... yes

checking return type of signal handlers... void

updating cache ./config.cache

creating ./config.status

kcreating Makefile

creating config.h

（2）執行：make 命令

[root@localhost rpc.rstatd]# make

rm -f rstat.h

rpcgen -h -o rstat.h rstat.x

gcc -DHAVE_CONFIG_H -I. -I. -I.     -g -O2 -c rup.c

rup.c: In function 'ointopoint_v5':

rup.c:256: warning: passing argument 6 of 'client->cl_ops->cl_call'?from incompatible pointer type

rup.c: In function 'ointopoint_v3'?

rup.c:292: warning: passing argument 6 of 'client->cl_ops->cl_call'?from incompatible pointer type

rup.c: In function 'main'?

rup.c:317: warning: return type of 'main'?is not 'int'?rm -f rstat_xdr.c

rpcgen -c -o rstat_xdr.c rstat.x

gcc -DHAVE_CONFIG_H -I. -I. -I.     -g -O2 -c rstat_xdr.c

rm -f rstat_clnt.c

rpcgen -l -o rstat_clnt.c rstat.x

gcc -DHAVE_CONFIG_H -I. -I. -I.     -g -O2 -c rstat_clnt.c

gcc -g -O2 -o rup rup.o rstat_xdr.o rstat_clnt.o 

gcc -DHAVE_CONFIG_H -I. -I. -I.     -g -O2 -c rsysinfo.c

rsysinfo.c: In function 'ointopoint_v3'?

rsysinfo.c:136: warning: passing argument 6 of 'client->cl_ops->cl_call'?from incompatible pointer type

rsysinfo.c: In function 'main'?

rsysinfo.c:160: warning: return type of 'main'?is not 'int'?gcc -g -O2 -o rsysinfo rsysinfo.o rstat_xdr.o rstat_clnt.o 

rm -f rstat_svc.c

rpcgen -m -o rstat_svc.c rstat.x

gcc -DHAVE_CONFIG_H -I. -I. -I.     -g -O2 -c rstat_svc.c

gcc -DHAVE_CONFIG_H -I. -I. -I.     -g -O2 -c rstat_proc.c

gcc -DHAVE_CONFIG_H -I. -I. -I.     -g -O2 -c rstat_main.c

rstat_main.c: In function 'main'?

rstat_main.c:82: warning: return type of 'main'?is not 'int'?gcc -g -O2 -o rpc.rstatd rstat_svc.o rstat_xdr.o rstat_proc.o rstat_main.o 

這以後能夠執行：make check檢查一下。

（3） 執行：make install 命令

[root@localhost rpc.rstatd]# make install

make[1]: Entering directory `/opt/rpc.rstatd'

/bin/sh ./mkinstalldirs /usr/local/bin

 /usr/bin/install -c rup /usr/local/bin/rup

 /usr/bin/install -c rsysinfo /usr/local/bin/rsysinfo

/bin/sh ./mkinstalldirs /usr/local/sbin

 /usr/bin/install -c rpc.rstatd /usr/local/sbin/rpc.rstatd

make[1]: Nothing to be done for `install-data-am'.

make[1]: Leaving directory `/opt/rpc.rstatd'

（4）執行：./rpc.rstatd 命令

啓動rpc服務。

[root@localhost rpc.rstatd]# ./rpc.rstatd

執行完成後沒有回顯信息，說明啓動成功。

（5）執行：rpcinfo –p 命令

檢查rpc服務的狀態.

[root@localhost rpc.rstatd]# rpcinfo -p

   program vers proto   port

    100000    2   tcp    111 portmapper

    100000    2   udp    111 portmapper

    100024    1   udp    797 status

    100024    1   tcp    800 status

    100001    5   udp    900 rstatd

    100001    3   udp    900 rstatd

    100001    2   udp    900 rstatd

    100001    1   udp    900 rstatd

[root@localhost rpc.rstatd]#

3.    可能會出現的錯誤

（1）若RPC服務沒有成功啓動。

（2）若目標主機上開啓了防火牆，阻擋了RPC服務。

在LR中添加時可能會出現以下錯誤：

Monitor name :UNIX Resources. Cannot initialize the monitoring on 10.1.200.65. Error while creating the RPC client. Ensure that the machine can be connected and that it runs the rstat daemon (use rpcinfo utility for this verification). Detailed error: RPC: Failed to create RPC client.

RPC-TCP: Failed to establish RPC server address.
