For monitoring purposes, there are two core components to be aware of:ĮSXi is the bare-metal hypervisor that runs on each physical server and enables vSphere to run VMs on that server. VSphere consists of a collection of components that make up its virtualization platform. Or, you can jump straight to the metrics. This includes metrics from both the physical and virtual components of your vSphere infrastructure, divided into the following categories:īefore diving into these metrics, let’s look at how vSphere works. In this post we will cover key metrics that provide insight into the health, performance, and capacity of your vSphere infrastructure. If you are a developer, monitoring vSphere will help ensure that your applications running on VMs behave as expected. For vSphere administrators, monitoring can help rightsize virtual machines so that resources are optimally distributed between them.

For instance, if your applications and workloads experience a bottleneck, it can lead to degraded performance or even downtime if you do not have the necessary resource capacity.

Performance and capacity management go hand-in-hand. This helps ensure that available resources meet the demands of the applications and services running on your vSphere infrastructure. If your organization is using vSphere to run applications, it’s vital that you pay close attention to your environment’s overall performance and capacity at different layers, including the VMs running workloads and the underlying hosts. Together, DRS and vMotion help make your virtual environment resilient and fault tolerant. In cases where downtime is expected for a particular server (e.g., for maintenance) or a server is overburdened, vMotion can also be used to migrate a VM to another server with zero downtime.

VMware also provides VM cluster management tools like the Distributed Resource Scheduler (DRS), which uses vMotion to automatically distribute shared physical resources to VMs based on their needs. Instead of using one physical server for each application you run, virtualization enables you to allocate a server’s resources across multiple VMs so you can host multiple isolated operating systems that run different workloads on a single machine, allowing more efficient use of the same physical resources and reducing spending on storage space and hardware maintenance. With vSphere, organizations can optimize costs, centrally manage their infrastructure, and set up fault-tolerant virtual environments. VMware’s vSphere is a virtualization platform that allows users to provision and manage one or more virtual machines (VMs) on individual physical servers using the underlying resources.
