Recently I have been watching the advanced management course of VMWARE. There are many management tools involved in this course, including Vsphere Client, Vsphere Web Client, ESXCLI, ESXTOP, vmkfstools, VMA, PowerShellCLI and so on.

Let's simply go over it:

Vsphere Client and Vsphere Web Client will not go into detail, which is used by every administrator. Web Client has a little more functionality than the client, but it is sometimes slower.

2.VMA is a linux-based VM appliance, similar to the role of a fortress machine. Download the ovf template directly from the Internet, and some initialization settings are required after installation. After the setting is completed, you can bind the host above.

ESXCLI is a powerful command. Type ESX directly and then press the tab key twice to see all the relevant ESX commands. The main focus here is on the ESXCLI command. Enter ESXCLI to display help, and enter at one level to view help information.

Here are a few examples directly:

Show firewall policy

To display the mounted storage information, you can directly use the linux command df-h

It can also be displayed through esxcli storage. It is worth mentioning that before VMFS6, if you deleted the hard disk configured by thin, you need to manually execute the esxcli storage command to reclaim space. After VMFS6, it is all realized automatically.

Another command is vmkfstools, which can be used to manage disks, vmfs upgrades, and so on

For example:

Display specific uuid and other information through vmkfstools

Create a 5g hard disk

Expand to 6g

In addition, there is a monitoring command ESXTOP, a top command similar to Linux, which has many options. You can check the performance of cpu, memory, hard disk, network and other indicators. We can check the help through h.

In addition to viewing real-time information, he can also save performance logs for a period of time, and then view them through third-party tools.

For example, take a value of 2 seconds and save all the results of 5 samples.

This result can be opened through windows's performance monitor.

PowerShellCli, this is a favorite of windows administrators. After downloading and installing the import module, you can use it. The old version is called through snapin, but after 6.0, it can be called through the module.
