I have the follwing Jmeter script, everything is ok except that the perfmon metric collector are throwing errors and I dont know what I am missing:
The error means that Perfmon Metrics Collector listener is not able to establish connection with the PerfMon Server Agent
Make sure you:
Download PerfMon Server Agent onto the machine running JMeter and on your 192.168.56.160 host
Run PerfMon Server Agents on both machines
Make sure that port 4444 is not blocked by firewall
See How to Monitor Your Server Health & Performance During a JMeter Load Test for detailed installation and configuration instructions

I checked with jp#gc – PerfMon Metrics Collector under Listeners
but that required Host and port number
now I have only host but not having port number
i checked that return me an error
Response code:Non HTTP response code: org.apache.http.conn.HttpHostConnectException
Response message:Non HTTP response message: Connect to *********** failed: Connection timed out: connect
You need to install ServerAgent application on the system you would like to monitor.
Then you need to launch it. By default the ServerAgent is listening on port 4444 for incoming TCP and UDP requests from the PerfMon Metrics Collector listener.
So you will need to set the host to the IP address or DNS hostname of the system you would like to monitor and the port to 4444 (make sure it's open in the firewall)

There is also SSHMon Samples Collector listener which doesn't require installation of any software on the system under test side, however it needs SSH server to be up and running there (it's pretty much common on Linux/Unix systems and can be enabled on Windows as well)
I would like to test the send/receive metrics when connected via a VPN using the JMeter tool then compare the results when not connected to the VPN. Would appreciate any thoughts on this subject.
I don't think there is something you have to do from JMeter perspective as traffic routing is the job for the VPN client so it should be sufficient just to execute the test 2 times:
1 test when the VPN connection is down
2 test when the VPN connection is up
The results can be compared using Merge Results Tool
If for some reason your VPN client doesn't pick up the traffic from JMeter to your application due to its configuration you can force JMeter to use your VPN network interface as the source IP address, the setting lives under "Advanced" tab of the HTTP Request Defaults configuration element
I've a distributed JMeter setup with 1 client (controller) and 2 servers (generators).
Now while a test is executing on the setup if a generator crashes in between, the controller gets hanged even after the test duration ends.
Is there a way to reconnect the controller with the generator after the generator comes up again during the same test execution?
No there is no such configuration option and it is advised to restart servers.
Usually this is due to connectivity issues between server and controller like port not open.
For reference properties have a look at:
https://jmeter.apache.org/usermanual/properties_reference.html#remote
For 1/ you can add this to user.properties:
client.continue_on_fail=true
server.exitaftertest=true
How can I find a Slave IP address to pass in case of starting Jmeter Master. As Jmeter slave has been successfully launched and waiting for a command from Master.
Anyone expertise in Jmeter help, please!
When you launch jmeter-server script it prints some diagnostic information to the stdout and this information includes the IP address the slave binds to, look for endpoint word:
See How to Perform Distributed Testing in JMeter article, it should help you to better understand JMeter's client-server execution mode
And of course you can determine the IP address by means of the underlying operating system i.e. using ipconfig command for Windows or ifconfig for Linux/Unix/MacOS
Error Screenshot I have recorded test scrip using smart meter.
But I when I tries to load the script "Rum smartmeter Test"
It gives following. I have no requirement of remote server as i wanted to run basic Testscript from local machine
*> Connection refused to host: 127.0.0.1; nested exception is:
java.net.ConnectException: Connection refused connect*
Just for the background please note that SmartMeter.io is based on Apache JMeter but adds new features such as one-click test reports, advanced scenario recorder, user friendly distributed mode, acceptance criteria and many others.
Looking forward for your suggestion.
Thanks.
Looks like SmartMeter is unable to start a load generator. The most common reason is that the required port 1099 is already occupied by some other program or the load generator can sometimes be blocked by your firewall. I suggest you restart your computer and try again. If it doesn't help, then you need to find out what is occupying that port. See for example How can you find out which process is listening on a port on Windows?
You should be able to get some information from logs/generator.log.
You can also run tests from SmartMeter Editor, the same way you would do in JMeter.
