Logs are essential for diagnosing and troubleshooting issues in VMware ESXi environments. Whether you’re facing host performance problems, VM crashes, or storage connection failures, collecting a complete log bundle is the first step. This guide walks you through three reliable methods—via vSphere Client, ESXi Host Client, and command line—to quickly gather the necessary logs for analysis.

In virtualization management, VMware Workstation and ESXi are commonly used platforms. Many IT operations teams need to migrate VMs between these two environments—for example, for

Configure vSwitch link aggregation and failover quickly using esxcli commands for flexible, scriptable network management.
Assign Active, Standby, and Unused uplinks and add NICs to vSwitches without the GUI.
Ensure high availability and optimized performance across your ESXi hosts.

Sometimes, a VM becomes unreachable due to network issues, leaving the ESXi host as the only point of access. In such cases, knowing how to retrieve files via SSH from ESXi can be a crucial skill for VMware administrators.

In this article, we explore the critical steps to investigate unexpected shutdowns and restarts of virtual machines in a VMware environment. Understanding the causes of these events is essential for maintaining system stability. We delve into various methods for analyzing VMware logs, including how to interpret key entries related to shutdown and restart events. By effectively identifying these issues, users can ensure a more reliable and efficient virtualized environment.
