A brief description: the following error pops up when LoadRunner monitors Linux resources:

Monitor name: UNIX Resources. Cannot initialize the monitoring on 192.168.52.189. 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.

The essence of the above problems is that rpc.rstatd is not installed in the Linux system and the service is not enabled.

So then we verify our conjecture:

First check to see if rpc.rstatd is installed

The following is a code snippet:

[root@localhost bin] # whereis rpc.rstatd

If there is no rpc.rstatd in the list

Found that rpc.rstatd is not installed on the system

Note: rstatd Rstat protocol allows users on the network to obtain the performance parameters of each machine on the same network.

Second, prepare the download package: download the rpc.rstatd-4.0.1.tar.gz installation package

Download address: http://sourceforge.net/projects/rstatd

Use ssh client to upload rpc.rstatd-4.0.1.tar.gz package to Linux / home/Michael/tool/ directory

Execute the installation package:

The following is a code snippet:

Tar-xzvf rpc.rstatd-4.0.1.tar.gz / / decompress rcp.rstatd

Cd rpc.rstatd-4.0.1 / / go to the rpc.rstatd directory

. / configure / / configure the installation of rc.rstatd, the following is in the default way

Make / / compile rc.rstatd

Make install / / installation

Four restart xinetd

The following is a code snippet:

/ etc/init.d/xinetd restart

5 modify the setting of disable to no in the three conf (rlogin, rsh, rexec) under the etc/xinetd.d directory

The following is a code snippet:

Cd / etc/xinetd.d / / go to the etc/xinetd.conf directory

Vi rlogin / / Edit disable=no, Savin

Vi rsh / / Edit disable=no, Savin

Vi rexec / / Edit disable=no, Savin

Six, start rpc.rstatd and detect

The following is a code snippet:

Rpc.rstatd / / start the rpc.rstatd process

Rpcinfo-p / / execute this command to check the status of the rpc service

[root@localhost xinetd.d] # rpcinfo-p

Program version protocol port

Program vers proto port service

100000 4 tcp 111 portmapper

100000 3 tcp 111 portmapper

100000 2 tcp 111 portmapper

100000 4 udp 111 portmapper

100000 3 udp 111 portmapper

100000 2 udp 111 portmapper

100024 1 udp 40879 status

100024 1 tcp 53726 status

100001 5 udp 899 rstatd

100001 3 udp 899 rstatd

100001 2 udp 899 rstatd

100001 1 udp 899 rstatd

When you see rstatd, the rstatd service has been started. You can use LR to monitor.

Seventh, use Controller in Loadunner to monitor Linux resources

1 in controller, drag the UNIX resources in Systeme Resourece Graphs to the right-click resource monitoring area

2 Select Add Measurements with the right mouse button, add the IP address 192.168.52.189 of the monitored linux, and select the performance metrics to be monitored. After confirmation, it indicates success ^ _ ^ as shown in the following figure

Some may prompt the computer to access the data that measures cpu utilization. This is because you do not have this resource metric. When you add the computer, you re-add the resource metric cpu and the relevant information you need to OK.
