Loadrunner监控linux之详解rstatd的安装

1.    前期准备

 （1）把rstatd文件解压到要监控的机器上。

 （2）打开终端，定位到rstatd文件夹下：查看文件夹中的内容以下：

[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.    执行步骤

（1） 执行：./configure 命令

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

creating cache ./config.cache

checking for gawk... gawk

checking for gcc... gcc

checking whether the C compiler (gcc ) works... yes

checking whether the C compiler (gcc ) is a cross-compiler... no

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）执行：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: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 

这以后能够执行：make check检查一下。

（3） 执行：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）执行：./rpc.rstatd 命令

启动rpc服务。

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

执行完成后没有回显信息，说明启动成功。

（5）执行：rpcinfo –p 命令

检查rpc服务的状态.

[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.    可能会出现的错误

（1）若RPC服务没有成功启动。

（2）若目标主机上开启了防火墙，阻挡了RPC服务。

在LR中添加时可能会出现以下错误：

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.
