When someone asks if there is a way to monitor their virtual machine (VM), my first question is always, “What do you want to monitor?” The second question I ask is, “Do you have any existing server monitoring tools that you can use, and if so, how do they work?” These two questions lead administrators
Today, we’re going to take a look at a very critical monitoring and resource management aspect of the modern data center: Your virtualization layer (logical). Pretty much all analysts agree that today’s data center is the driving engine behind major business initiatives. Most of all, today’s organizations rely heavily on their data center to enable
Although there may be many x86 virtualization platforms, such as VMware ESX, Xen, Microsoft Virtual Server 2005 R2 to name a few, monitoring is pretty much the same from one to the next. In this article, I will discuss what is involved in monitoring a virtual infrastructure, including monitoring the physical host servers, the virtual
Virtualization Monitoring Virtualization monitoring ensures that a virtualized IT infrastructure performs optimally and that virtual resources are properly allocated. Virtualized infrastructure monitoring requires collecting and evaluating key performance indicators (KPIs) for both physical and virtual components. For example, VMware KPIs include: VMs Hosts Resource pools Datastores Clusters Data centers Because physical resources are shared between
There are five key areas that a good virtualization management solution should cover to effectively manage your virtual environment. By focusing on these areas, you can ensure that you stay on top of the big picture and also eliminate any potential threats that may disrupt or impact the proper operation of your virtual machines. The
The term “mobile devices” encompasses a wide array of gadgets ranging from mobile phones, smartphones, tablets, and GPS units to wearables and PDAs. What they all have in common is the fact that they can contain a lot of user information. Mobile devices are right in the middle of three booming technological trends: Internet of
Most would agree that the golden age of mobile forensics is over. There is no longer an easy way to get through the passcode in new iOS devices running the latest version of iOS. Chip-off acquisition is dead for iOS devices due to full-disk encryption, while physical acquisition of Apple hardware is dead since the
It seems nearly everyone owns some sort of mobile device these days. Therefore, it’s not surprising to learn that smartphone usage has exceeded computer usage. Given the rapid growth of these devices, it is rare for investigators to conduct a digital forensic investigation that does not include a smartphone or mobile device. For many, the
Mobile device data acquisition, in addition to traditional digital data sources, is a key component of any defensible discovery protocol. However, acquisition of mobile device forensic data is often far more complicated than many people realize and can encompass much more than just cell phones. As the personal and professional use of mobile device technology
Mobile device forensics is a branch of digital forensics relating to recovery of digital evidence or data from a mobile device under forensically sound conditions. The phrase mobile device usually refers to mobile phones; however, it can also relate to any digital device that has both internal memory and communication ability, including PDA devices, GPS
