Automating Services based on vCenter Custom Attributes – Updated
May 18th
It’s been awhile since my last post, I’ve been busy traveling around and what not. Today, I’m going to be sharing some new code that does something pretty cool in vFoglight/Foglight. As mentioned in a previous article, you can use Dynamic Managed Components to create services based off any attribute or query you can come up with. Well, what I have to share today will do all of this work for you.
Let’s say you have an attribute in vCenter called Business Units. Each VM in vCenter has a value listed, some are assigned to Sales, some to Marketing, so on More >
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 >
vFoglight Virtualized – Part 2
Oct 8th
Continuing from the last post, we are now going to explore installing vFoglight 5.2.6 into a VM and start pointing vCenters at it.
For the purpose of the test I’m using the following configurations to start and we will grow it as we add more vCenters and thus more VMs or as performance dictates.
vFoglight VM OS – Windows 2003 R2 x86_64 vCPUs – 2 Memory – 2G Hard Drives – 3 VMDKs on Raid Group 2 (only VMDKs on the Datastore) 10G C:\ (OS Partition – 64k aligned) 5G D:\ (Swap Partition 4G Fixed size – 64k aligned) 30G F:\ (Application More >
vFoglight Virtualized – Part 1
Sep 18th
I’ve had a lot of virtualization customers ask me, both large and small, if Vizioncore’s vFoglight will run in a VM or as a virtual appliance. My reaction, of course, is it will run just like on a physical host. vFoglight has always been supported running in a VM by Vizioncore. Like any application you virtualize, there are things you can do to ensure proper performance and more importantly get the most out of the environment.
Let’s look at the different parts of vFoglight and talk about each one. There are three components that can be installed together or installed separately. 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 >
