The same script is running successfully for the web application running on the localhost.
Am I missing any configuration that need to be done for testing the applications running on remote servers.
Any help would be appreciated.
Please refer the following screenshot to set the proxy settings in the Jmeter.

In my scenario Jenkins master is available in Linux machine and i can access this in my Local windows machine also.
I created one windows slave using launch method as "Launch agent by connecting to the master".As per guidelines , i created one folder in my windows and i pasted that slave and agent jars in that folder.
While I am trying to run the slave-agent i am getting error like below. (Screenshot attached)
I tried with 2nd option as well i.e i took the provided command in Jenkins slave and i pasted that into command. again it is giving failed to connect error message. Please find below error message.
I am new to this configuration.
Do i need provide my slave machine ip into the master machine or do i need to install any other things related to this. can someone please help me out.

Slave-agent error
Issue resolved. In my case whenever we are creating new slave it is generating new IP which is not having server. Here just we are creating another node for the existing server.
Whenever we are launching the slave using agent.jar with the slave IP we are getting timed out error. Instead of going with slave IP if we go with master IP , agent is launching successfully.
Please find below example.
If i try with slave IP(Below IP)
java -jar D:\Jenkins\agent.jar -jnlpUrl we are getting error
http://120.231.140:8080/computer/My_slave_node_name_Windows10/slave-agent.jnlp -secret anHexadecimal_Long_Number5d094b1f577bc772b65b7277ac57 -workDir "D:\Jenkins"
Below IP is master IP. Agent launched successfully.
java -jar D:\Jenkins\agent.jar -jnlpUrl http://120.241.141:8080/computer/My_slave_node_name_Windows10/slave-agent.jnlp -secret anHexadecimal_Long_Number5d094b1f577bc772b65b7277ac57 -workDir "D:\Jenkins"
There is change in IP for slave and master. If i launch the slave ip from the cmd we are getting a timed out error.
The other three possibilities are
Whitelist slave IP in master Instance security groups level(all traffic or required ports).
By default windows server will block with IE security settings so diable by following below.
"Enter Server Manager in Windows search to start Server manager application. Select Local Server. Navigate to the IE Enhanced Security Configuration property, select the current setting to open the property page, select the Off option button for the desired users, and then select OK"
Configure a port number for TCP JNLP connection and whitelist it on instance security groups.
Manage Jenkins > Configure Global Security > Enable security > TCP port for JNLP agents: Fixed.

For Deployment of war file in tomcat server ,
I am facing a several issues.
Error :
Credentials At Jenkins :
tomcat-users.xml File :
Still I am facing the same issue. I had searched in google and stackoverflow but still i can't found the correct answer.
Can Any one help me in this ?
Your error message is a connection refused: connect exception. You should check the following:
Your Tomcat server is up and running on port 8082 at the same server where your jenkins server is running (localhost). To make sure, run: telnet localhost 8082 from the same server commandLine ( I see you are in windows). If it connects then your Tomcat server is OK.
Check if the manager application of Tomcat is deployed. Try to load the following web page and check if exists: http://localhost(or hostname of server):8082/manager/html
Try to disable the windows firewall and any other firewall you may have (or antivirus firewall) and check if it prevents jenkins to connect to Tomcat (again check with telnet command)
In jMeter, I have installed perfMon plugin that listens to 4444 port successfully. My application runs on localhost:8080. It seems when I give default http port as 8080 as per the attached image, api works fine but no graph for perfMon metric plugin. But when I give http default port as 4444, perfMon shows graph but API fails giving 404.
How can I run both my application in localhost:8080 and listen to same port using server agent/ perfMon agent (which runs on 4444 port)?
FYI. I need to monitor the tomcat server(where my tested application resides).For that I have installed server-agent in my tomcat server.Edited jmeter.properties like below: remote_hosts=localhost:4444
I am running my application in tomcat of docker container and I have installed perfMon server agent locally at my system /opt directory. Does it has to installed somewhere specific directory ?
In server agent console, I am getting error

as I have set the pid in metric parameter as follows(my tomcat pid =728 in docker)
every time after hitting API in jMeter, it is saying client disconnted
I got the solution. When it says "client disconnected", it is not an error, it is info. I forgot to change pid in metric parameter whenever I run the server.
I have downloaded apache karaf2.3.3 (on felix) on several CentOS6.4 machines. I see this issue only in a few machines. When I try to install a feature using the following commands
$KARAF_HOME/bin/start
$KARAF_HOME/bin/client "features:install myfeature"
I get the following stack trace:

Looks like client fails to connect to karaf. Firewall is shutdown on all of the machines. Anyone knows why this could be failing? The feature gets happily installed if run karaf in console mode with /bin/karaf and type in the same command
My guess is that the port you defined for the remote Karaf console was already in use by another application before the Karaf installation. As such the wrong application accepts the link, cannot make anything of the data and resets the connection. I would suggest to stop Karaf, check with netstat or via telnet localhost <port> whether the port Karaf is configured to listen on is already in use, and find the related application. As an alternative, you can configure Karaf to use a different (not used) port. See for example this page

Can anyone tell me what is wrong?
I had exactly this problem just now and still have not solved it. However, I suspect it is happening because of proxy issues.
Is it possible to try setting the manager URL to http://localhost
rather than http://192.168.2.X? This worked for me, showing that the credentials were at least correct and the module functions. When I switch the manager URL back to a remote machine or the FQDN of the local server, it again failed. This indicates to me something proxy related.
The only trouble then is configuring the proxy settings for Jenkins, especially http.nonProxyHosts. If you can do that maybe you'll have more luck than me. I cannot get the Jenkins System Information proxy values to change no matter what I do!
Also manually test from a browser on both the build server and elsewhere your access to the manager URL: http://192.168.2.X/manager/list
