I am trying to connect my DB with JMeter (JDBC Connection) but VPN is required to access the DB. I have VPN details with me but know how can I connect with my DB using JMeter?
Thanks in advance
If you have active VPN connection (like the machine you're running JMeter on is connected to the VPN at the moment of test execution) you don't need to do anything, JMeter will be able to connect to the database.
If you don't want to have the VPN connection up all the time and looking for the way of connecting to the VPN prior to executing your test you can:
Use setUp Thread Group and OS Process Sampler to establish the VPN connection before your main Thread Group(s) containing JDBC Test Elements start
Eventually you might go for tearDown Thread Group to disconnect the VPN after main Thread Group(s) execution end.

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 am trying to connect 100 mqtt clients to iothub using jmeter.
In mqtt connection panel, for pwd, am using iothubowner connection string (available in shared access policy page in azure portal), from which SAS get generated & using the same in pwd for all 100 clients.
connection is successful as well.
but when i try to use the respective client connection string, from which SAS get generated using device explorer, get applied in pwd and the connection get failed.
Any help pls.
JMeter executes Samplers upside down by each virtual user so you don't need to duplicate this Gateway Connect sampler, just define 2 threads (virtual users) in the Thread Group and each thread (virtual user) will execute Gateway Connect sampler and establish its own connection with the broker.
The credentials can be parameterized using i.e. CSV Data Set Config so each virtual user would connect with its own username/password combination

Am not sure still why respective connection string is creating props, but in such case, the recommended solution is to use iothubowner connection string from the shared access policy page. It's quite successful.
I'm using JDBC connection configuration and JDBC request sampler to fetch test data from database for large set of data for my test requirement.
My question is, if we connecting to database through connection configuration and JDBC sampler to fetch data from database then how we can close the connection from database like we are having other performance testing tool Neoload.
As of now what i'm seeing from total number of active connections in sql server using sp_who2 or below query is that JDBC connection not closed after jmeter test execution completed.
Question is, How to closed JDBC connection if my purpose to use is completed within the script execution?
Any help would be appreciated.
If this is something you really need, you can invoke DataSourceElement.getConnection() function from any JSR223 Test Element which will return an instance of java.sql.Connection so you will be able to call Connection.close() function.
Something like:
org.apache.jmeter.protocol.jdbc.config.DataSourceElement.getConnection('foo').close()
where foo is your connection pool variable name.
There's an issue with JDBC Connection Configuration when using connection pooling
Maximum number of connections allowed in the pool. In most cases, set this to zero (0). This means that each thread will get its own pool with a single connection in it, i.e. the connections are not shared between threads.
If you set 0 connections and problem still persist, open an issue for JMeter
I have a list of VPN server credentials I could use to connect to the Internet.
I want to test each server's speed of upload/download.
One option is to make a script to connect to each VPN server and transfer a couple of files back and forth to get the average upload/download speed.
But this method is slow and time consuming(since I need to wait for the VPN client to connect to the VPN server). Is there any quicker way to test VPN servers speeds or maybe improve my current method?
Make Your VPN server as Iperf Server and check the vpn server speed on single and parallel connections with iperf client available on multiple platforms.
Read the Docs for more
https://www.linode.com/docs/networking/diagnostics/install-iperf-to-diagnose-network-speed-in-linux/
however it is recommended to take speedtest after vpn connection as Encryption and bad configuration can also degrade speed.
how to hit total 1000 ssh commands using jmeter by 1000 users (1command/user) using 1 ssh connection.
Also is there a way to do ssh connection using private connection in Jmeter ?
Any leads will be helpful.
Thanks Balaram
Your test doesn't make a lot of sense a it is not realistic scenario, i.e. you cannot have 2 users sharing one SSH connection as it is not possible at the SSH protocol level
Using JMeter you can open 1 session per user, you can use the same username and password (or public key), however each JMeter thread (virtual user) will create a separate SSH session (connection) to the server.
So you can implement the above scenario in JMeter, the easiest way is going for SSH Command sampler which can be parameterised via i.e. CSV Data Set Config
You can get SSH Sampler as a part of SSH Protocol Support bundle using JMeter Plugins Manager
