Associating Custom Attributes in vFoglight
Jan 10th
I am often asked how to associate a custom attribute in vCenter to a group in vFoglight. To do this in vFoglight we create a Service. For an example I’m going to use the Custom Attribute called “Business Unit” to create service for all VMs that have “Business Unit” set to “Sales”
First, we need to turn on Custom Attribute collection. In vFoglight Pro 6.0, the default collection is to not collect CA’s. To change this, we must navigate to the collector installation path.
- If you have a default installation it is C:\Program Files\Vizioncore\vFoglight\VMware Agent
- Edit the FoglightAgent.WinService.exe.config with your favorite text editor

vFoglight Virtualized – Part 3
Oct 18th
In the first two parts of the series we’ve been talking about the basics of vFoglight and how the system components operate. In the previous post we were testing about 30 VMs, so now we’ve added another 70VMs bringing the total up to 100. Again, we can look at the JVM Memory Usage and Load Estimator to see how taxed the system is.

Figure 2 – Load Estimator
As you can see in the figures, there is data growth over time and periodic spikes in load. What is happening to cause the spikes? Garbage Collection, GC for More >
Capacity Planning – Part 2
Aug 7th
Continuing from my last post about capacity planning, Capacity Planning Part 1, I am going to discuss some of the ways that you can find your current capacity, as well as future capacity. While there are many tools out there that can help you, I’m going to focus on one or two concepts of capacity planning.
So the first thing to consider is how you wish to model your environment. This can be the simplest and the hardest part. If you go ask Gartner, IDC or one of the many large research firms, they will tell you there are lots of More >
Capacity Planning – Part 1
Aug 1st
One of the most talked about areas in systems monitoring these days seems to be capacity planning; and it’s one that’s heavily clouded. The main reason is that every environment is different. Even though we all tend to run similar application stacks, how we use them is unique to our individual behaviors and business requirements.
In most cases this causes us to look for tools that can develop simple models, with virtualization being put into those models. Recently I spoke with several SMB & Enterprise level users and they told me that they’re essentially looking for a way to take a More >
