Review of Denamik Analyzer

Written by Ingmar Verheij on May 10th, 2013. Posted in Performance testing

Denamik introduces the Denamik Analyzer, an add-on to the Denamik LoadGen product. With Denamik LoadGen one can perform load- and stress tests on hosted shared and hosted private infrastructures like Citrix XenApp and XenDestop.

While the LoadGen executes a test and gathers data about the performance metrics and response times, visualizing and analyzing the data required a third party solution and knowledge about the performance indicators. The Denamik Analyzer now enables you to analyze the captured data, create and save charts and start creating a report in minutes.

I’ve had the opportunity to play with an early release of the Denamik Analyzer in my lab and get some hands-on experience.

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.

Exchange 2003 Management Pack Storage Add-On

Written by Ingmar Verheij on April 27th, 2011. Posted in Operations Manager

During an implementation of System Center Operations Manager (SCOM) a customer asked me how he can retrieve information about Exchange mailbox stores for trend analysis. Unfortunately the managemeng pack supplied by Microsoft does not collect the size of Mailbox Stores in the datawarehouse.

So I’ve created an add-on for the Microsoft Exchange 2003 Management Pack which adds a rule for collecting the size of Mailbox Stores.

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.

The challenge of printer drivers in a multiuser environment
The first terminal server implementation i’ve done was a Windows NT 4 Terminal Server. This is where i’ve learned (the hard way) that printer drivers and a multiuser enviroment is a snake pit. Finding the right driver for the printer is a difficult job which was done by trial-and-error.
