VMware vSAN ESA - storage performance testing

I have just finished my first VMware vSAN ESA Plan, Design, Implement project and had a chance to test vSAN ESA performance. Every storage should be stressed and tested before being put into production. VMware's software-defined hyperconverged storage (vSAN) is no different. It is even more important because the server's CPU, RAM, and Network are leveraged to emulate enterprise-class storage.

Monitoring VMware vSphere with Zabbix

Source: https://vmattroman.com/monitoring-vmware-vsphere-with-zabbix/

Zabbix is an open-source monitoring tool designed to oversee various components of IT infrastructure, including networks, servers, virtual machines, and cloud services. It operates using both agent-based and agentless monitoring methods. Agents can be installed on monitored devices to collect performance data and report back to a centralized Zabbix server.

Zabbix provides comprehensive integration capabilities for monitoring VMware environments, including ESXi hypervisors, vCenter servers, and virtual machines (VMs). This integration allows administrators to effectively track performance metrics and resource usage across their VMware infrastructure.

In this post, I will show you how setup Zabbix monitoring with VMware vSpehre infrastructure.

What is ESXi Core Dump Size?

ESXi host Purple Screen of Death (PSOD) happens when VMkernel experiences a critical failure. This can be due to hardware issues, driver problems, etc. During the PSOD event, the ESXi hypervisor captures a core dump to help diagnose the cause of the failure. Here’s what happens during this process.
