The eG VM Monitor extends the eG Enterprise monitoring technology to virtual environments. Using a patent-pending In-N-Out MonitoringTM approach, the eG VM Monitor provides a comprehensive view of a vSphere/ESX server, including the performance of the VM kernel, the service console and all of its virtual machines. Agent-based monitoring can be used for ESX servers, while agentless monitoring can be used for ESXi servers. When agent-based monitoring is used, eG agents only have to be installed on the vSphere/ESX server -- not on individual guests. Using vSphere APIs, the agents provide an “outside view” of a guest VM’s performance. The relative resource usage levels of the guest VMs show where the performance hogs exist. To complement the outside view, the eG agent obtains an “inside view” that details the user activity, resource allocation and the application mix running inside the VM guest operating system. All the capabilities of agent-based monitoring are also available with the agentless monitoring option for VMware vSphere/ESX servers. The eG VM Monitor automatically baselines all the metrics it collects, so that IT administrators can be informed proactively of any deviations from the norm. No other virtualization monitoring solution offers this combination of features.
The dependency of the virtual machines to physical machines is determined dynamically, so as to support the VMware VMotion® Live Migration technology. A patented root-cause diagnosis engine analyzes the service topology graphs and the virtual-to-physical machine mappings to pin-point where the problems areas in the infrastructure lie.
