I now the best practices with Jmeter, but I need to run it in GUI mode.
I have installed jmeter v5.2 on a CentOS virtual machine and I get connected through remote desktop from a windows machine. Jmeter runs normally when I execute from the virtual machine.
Jmeter direct from virtual machine
The problem is when I connect through a remote desktop, then I start Jmeter and I get this:
Jmeter from remote desktop
I review the logs from xrdp and there is nothing wrong, can u help me please, some ideas?
Make sure to update your Java to latest version, it might be the case you're suffering from a bug.
If this doesn't help - try setting adding the following lines to system.properties
sun.java2d.opengl=true
sun.java2d.xrender=false
you might also want to not to use this dark theme, try setting different look and feel, i.e. System, in user.properties
jmeter.laf=System

I would like to know open a GUI of a software called datacenter datastax which is a UI for Cassandra where we can manipulate the data.
Firstly, I want to install datacenter on my office server where multiple VMs are setup. Out of one of those VMs, I have created a fresh 'ubuntu server' VM and install the datacenter within. Since ubuntu server is only based on CLI but the data center is all GUI. How come I achieve this? I mean I want to access the GUI of this software while it's installed within a ubuntu server.
Reason for me doing this is because every person within the office can access the GUI of the datacenter when I share them the ip or whatever.
Please help me with this. Ill highly appreciate it.
You need to export the console from the server to the machine you want to access GUI from.
Something similar like this export DISPLAY=":0.0" where you replace ip_address with the ip address of the machine that you want to send GUI to, if the machine is some *nix machine. Then run the command to start the GUI. After this, the GUI should be redirected to the machine having the
If it is a Windows machine, you will need to run xming on it.
Also, please note that this is not a Cassandra related question, even if you want to start a Cassandra related GUI.
I'm trying to introduce continuous integration in an old project, and we've got quite specific situation - it's possible to put the CI server only on our test server that runs on CentOS. The server has quite a lot of unused RAM and CPU capability.
However, we need to run Ant builds on Windows (this also used to be how the project did packaging before), however it turned out that not the same output (after binary compare) is produced by just using Unix versions of Java and Ant.
I drew up a diagram of how in my mind it could work, but I'm really wondering whether that is even possible (with already given tools).
The black part is implemented, I'm curious whether the red part could be possible. Could the Jenkins slave communicate with master on different OS?
It should be possible. I have a feeling you will need to play with your network settings. But if before you start changing anything see if you can start a headless slave by following these directions: https://wiki.jenkins-ci.org/display/JENKINS/Step+by+step+guide+to+set+up+master+and+slave+machine
Using VirtualBox for CentOS, it will possible to run a Windows VM on your CentOS host.
I'm not sure you need Docker to launch your Jenkins slave.
It maybe better to use a standard JNLP Windows service to connect your Windows slave to Dockerised Jenkins master.
If the master is not able to view the Windows node using this method, you may have to tweak your network configuration on the Windows VM.
But I'm not sure it's necessary.
I am trying to create a dev box for SharePoint 2010 Server utilizing the following:
http://blogs.msdn.com/b/cjohnson/archive/2010/10/28/announcing-sharepoint-easy-setup-for-developers.aspx
So first of all this is new to me. I understand that these are instructions are for dual boot in Windows Native, but I am more interested in using a VHD/image of the OS to run on VMWare.
I have tried creating an image of a running virtual machine with sysprep tool, but hit a dead end with capturing the image to a file that I can reference within the running machine to run the scripts against.
I took a look at Diskpart on TechNet, but as I am new to this, I am not sure this is what I want to do?
I tried installing to the local host (virtual machine that is running) and am getting an error there also; fails at Windows Identity Framework.
It is a clean install of Windows 7 (literally nothing else), and the UAC has been disabled.
Is there any insite, help, or advice anyone can provide me regarding this? I would really appreciate it as I have to get working on the development aspects of SP (workflows, web parts,etc), and need a dev env, and I can't seem to get anywhere with this.
Thanks

First with the background...
We have a Linux server that supports multiple projects.
The Clearcase server and repository are installed on this Linux server.
Different projects require different cross-compilers and libraries, and all of them are installed on the server.
User can choose different tool sets by running different scripts, which exports different environment variable values such as include paths and compilers.
User needs to run cleartool to mount the repository.
Developers develop in Eclipse and have two options:
SSH into the server and run Eclipse through with X11 tunneling.
Install Eclipse locally on their Windows machine and invoke builds from the SSH terminal.
Now:
Problem with #1 is that Eclipse operations (typing, content assist, etc) are extremely laggy.
Problem with #2 is that the developers need to go through extra hoops to build their code.
This is what I have tried:
Set up Remote System Explorer, which allows remote editing of files and remote running of the compiler:
How to build a c++ project on a remote computer in Eclipse?
This approach works perfectly for files that do not need special environment variable values and mounting of Clearcase repository, but I could not figure out how to get all of these things to integrate.
It would be great if someone can let me know how I can direct RSE to run a script (may be different per project) to set the environment variables and to run the cleartool commands to mount the repository so that it can locate the files.
The cleartool command arguments would be different per user for setting up a particular view.
Some extra info that may help:
I have root access to the development server
The Clearcase filesystem is mapped to a drive on the Windows machine
Thanks in advance for saving me hours of frustration dealing with a slow network!
==================
Additional detail per comments:
- The VOB storage is located locally on the Linux server. We would SSH to the server and start Eclipse there, therefore the delay should not be due to dynamic vs snapshot view and GUI performance seems to be the real problem.
- We also mount the same view on Windows by using Region Synchronizer. When running the local copy of Eclipse installed on Windows, there is no performance problems.
So this question can probably be solved by answering either question:
1. How to improve X11 performance such that development on Linux will suffice?
2. How to set up Windows Eclipse to perform all the steps mentioned above when building projects?
I came here a similar question to your part two, but alas, no one has answered it. However, I have an answer to your part one: https://www.nomachine.com/. It speeds up X11 forwarding considerably.
I'm currently working on a server-side product which is a bit complex to deploy on a new server, which makes it an ideal candidate for testing out in a VM. We are already using Hudson as our CI system, and I would really like to be able to deploy a virtual machine image with the latest and greatest software as a build artifact.
So, how does one go about doing this exactly? What VM software is recommended for this purpose? How much scripting needs to be done to accomplish this? Are there any issues in particular when using Windows 2003 Server as the OS here?
Sorry to deny anyone an accepted answer here, but based on further research (thanks to your answers!), I've found a better solution and wanted to summarize what I've found.
First, both VirtualBox and VMWare Server are great products, and since both are free, each is worth evaluating. We've decided to go with VMWare Server, since it is a more established product and we can get support for it should we need. This is especially important since we are also considering distributing our software to clients as a VM instead of a special server installation, assuming that the overhead from the VMWare Player is not too high. Also, there is a VMWare scripting interface called VIX which one can use to directly install files to the VM without needing to install SSH or SFTP, which is a big advantage.
So our solution is basically as follows... first we create a "vanilla" VM image with OS, nothing else, and check it into the repository. Then, we write a script which acts as our installer, putting the artifacts created by Hudson on the VM. This script should have interfaces to copy files directly, over SFTP, and through VIX. This will allow us to continue distributing software directly on the target machine, or through a VM of our choice. This resulting image is then compressed and distributed as an artifact of the CI server.
Regardless of the VM software (I can recommend VirtualBox, too) I think you are looking at the following scenario:
Build is done
CI launches virtual machine (or it is always running)
CI uses scp/sftp to upload build into VM over the network
CI uses the ssh (if available on target OS running in VM) or other remote command execution facility to trigger installation in the VM environment
VMWare Server is free and a very stable product. It also gives you the ability to create snapshots of the VM slice and rollback to previous version of your virtual machine when needed. It will run fine on Win 2003.
In terms of provisioning new VM slices for your builds, you can simply copy and past the folder that contains the VMWare files, change the SID and IP of the new VM and you have a new machine. Takes 15 minutes depending on the size of your VM slice. No scripting required.
If you use VirtualBox, you'll want to look into running it headless, since it'll be on your server. Normally, VirtualBox runs as a desktop app, but it's possible to start VMs from the commandline and access the virtual machine over RDP.
VBoxManage startvm "Windows 2003 Server" -type vrdp
We are using Jenkins + Vagrant + Chef for this scenario.
So you can do the following process:
Version control your VM environment using vagrant provisioning scripts (Chef or Puppet)
Build your system using Jenkins/Hudson
Run your Vagrant script to fetch the last stable release from CI output
Save the VM state to reuse in future.
Reference:
vagrantup.com
I'd recommend VirtualBox. It is free and has a well-defined programming interface, although I haven't personally used it in automated build situations.
Choosing VMWare is currently NOT a bad choice.
However,
Just like VMWare gives support for VMWare server, SUN gives support for VirtualBOX.
You can also accomplish this task using VMWare Studio, which is also free.
The basic workflow is this:
1. Create an XML file that describes your virtual machine
2. Use studio to create the shell.
3. Use VMWare server to provision the virtual machine.
