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

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

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 >
