Unable to install/activate LoadBot (Denamik LoadGen)

Written by Ingmar Verheij on June 22nd, 2012. Posted in Performance testing

Denamik LoadGen can perform load- and stresstest on SBC and VDI environments by to simulate users. To distribute the load systems called ‘LoadBots’ are used to generate the load, resulting in an architecture with horizontal scaling capabilities.

Before a system is called a LoadBot an agent needs to be installed. The installation of the LoadBot is done from the central management console, the Director. The installation is pushed to the remote system and results in a small service running in the background.  The LoadBot can be (de)activated on demand from the central management console.

In this article I’ll explain the steps involved when installing (or activating) the LoadBot software on a remote machine. There are some common issues (like name resolution, firewall configuration, etc.) that I’ll explain as well.

Your machine(s) everywhere

Citrix Synergy starts tomorrow in San Francisco. From wednesday 12 may till friday 14 may all updates, new features and other news is presented to the public. One thing that’s excites me most is the upcoming XenClient, a baremetal hypervisor.

Combined with a VDI solution like XenDesktop the XenClients enables the customer to take the VM outside the datacenter en get it onto his desktop / laptop using his local resources. Altough this sounds a bit like we were used to work, and in fact it is, there is a big difference.

Stresstest your printer drivers

Written by Ingmar Verheij on November 6th, 2009. Posted in Performance testing, Printing

A few days ago I wrote an article about the issues with printer drivers in a multiuser environment. In this article I advised you to test you’re printer drivers in a acceptance environment, preferably with real users testing. This can be achieved with a LoadTest / StressTest tool like the Denamik LoadGen, which is free up to 25 users. And since testing with 10 users is enough to stress a driver, there’s no need to buy a license.

Today I would like to tell you how this is done, step-by-step.

The goal
We’re going to try to use the printer environment as realistic as possible, but where focusing on the worst case scenario. Because where trying to find out whether the printer driver is functioning correct when multiple users are printing, where going to simulate that a number of users are printing to printers using the same printer driver.
