In addition to the security and hardening aspects of vSphere, the new 6.7 version brings other important related features(though some were introduced with version 6.5), such as VM encryption, encrypted VMotion, secure boot support for VMs, and secure boot plus cryptographic hypervisor assurance for ESX Chapter 17, Analyzing and Optimizing Your Environment, covers the native tools used to monitor your environment for performance analysis or for possible issues in order to improve the virtual environment and workloads. This chapter focuses on monitoring different critical resources, such as computing, storage, and networking resources, across ESXi hosts, resource pools, and clusters. Other tools, such as vRealize Operations and third-party tools, will also be described briefly Chapter 18, Troubleshooting Your Environment, covers the native tools used to troubleshoot performance issues and other issues in a vSphere environment.
