You can do a lot of configuration of ESXi through the GUI, but one thing I’ve found that you cannot do is configure SNMP.
I can see in the GUI that SNMP service is stopped, and that’s about it:
So here’s how to enable SNMP and configure the community string/firewall on ESXi 6.0 or 6.5:

本页详述了在一台VMware ESXi（ESXi 5.5）服务器上部署安装OMSA的通用做法，包括OMSA软件的获取方法和安装步骤。
演示环境：
PowerEdge R620, VMware ESXi 5.5
我们需要在管理员的操作机（笔记本）上，通过CLI进行远程ESXi服务器的组件安装和配置。请先到VMware的官网下载下面的CLI。（用户可以免费注册，再下载该安装包），并提前安装好。
https://my.vmware.com/cn/web/vmware/details?downloadGroup=VCLI550&productId=353
本例使用VMware vSphere Client 5.5管理ESXi服务器：包括关闭ESXi服务器上虚机，以及将ESXi服务器进入或退出维护模式。当然，也可以使用其他用户习惯的工具。
本例VMware vSphere Client 5.5的下载地址如下：
http://vsphereclient.vmware.com/vsphereclient/1/2/8/1/6/5/0/VMware-viclient-all-5.5.0-1281650.exe
请先提前下载安装在管理员的Windows操作机上。 继续阅读
This script is a Nagios plugin to monitor the hardware of ESX and ESXi servers. It can also be used as standalone script to check the hardware – Nagios isn’t necessary to run it. The plugin is written in python, so you need to have python installed. See Requirements for more information. 继续阅读
If you ever land up in a situation where your vCenter Server setup is stuck at the directory services stage and in the “VMINST.LOG” found under %temp% u see it trying to perform the following..
将一台服务器用过的磁盘加入到ESXi主机中，通过vSphere Client添加存储一直提示 esxi在x.x.x.x上调用对象 “ha-datastoresystem”的“HostDatastoreSystem.QueryVmfsDatastoreCreateOptions”
用ssh连上esxi服务器，fdisk -l查看磁盘信息如下：
/dev/disks # fdisk -l

把该硬盘（Disk /dev/disks/naa.5000c500213f8657）模式改为msdos即可以vSphere Client上加载硬盘。
使用以下命令：
partedUtil -h获得帮助。
Create New Label (all existing data will be lost): mklabel <diskName> <label>
使用这个创建新卷标选项，所有数据会丢失。
/dev/disks # partedUtil mklabel /dev/disks/naa.5000c500213f8657 msdos
/dev/disks # fdisk -l

This article covers setup of simple and cost-effective 2-node Proxmox VE cluster featuring locally installed GlusterFS as shared filesystem for cluster VMs. Through this solution is not intended for mission critical or enterprise needs, its ease and ability to run on bargain priced hardware makes it interesting for non-profit organisations, labs or clustering enthusiasts.
This HOWTO implies you have 2 freshly installed Proxmox VE 3.3 nodes:
pve-node-01 (IPv4 10.10.0.1) and pve-node-02 (IPv4 10.10.0.2) connected to the 10.10.0.0/16 private network. Keep in mind that your actual setup may differ and you may need to change some of commands in this HOWTO to suit your needs. 继续阅读
We generally do both dedicated and VPS hosting for our websites, apps and some premium projects we run for others.When we choose to have VPS servers (aka virtual machines or VMs for short) instead of dedicated servers, we usually opt for VMware‘s free ESXi 5 and install Ubuntu Server as the OS for the VPSs we create on top of ESXi 5. It may not be as friendly as some VPS providers like Amazon, Rackspace etc. but you got more control and it’s on YOUR hardware (pretty important actually!)…
Now, when you build a VPS on VMware, you start with say 40GBs of hard disk space. You install the OS, setup the server, move the sites on this new server and you’re on. But what happens when there’s no more room on the server for your site or sites and you need to add more disk space?
This issue occurs if the virtual machine Configuration Parameter isolation.tools.setinfo.disable is set to True. When configured this way, the guest operating system does not pass IP Address and DNS Name information to the ESXi/ESX host for display in vCenter Server. Newly created virtual machines without this virtual machine Configuration Parameter set to True do not exhibit this problem.
Note: It is not required for the vCenter Server to be apart of the domain for the fully qualified domain name of a managed virtual machine to be displayed; however, if the virtual machine is not member of domain, then DNS name on virtual machine’s Summary tab will display the hostname only. 继续阅读
