Well, today it's time for another post about log collection, how to treat them and above all how to visualize them; in this document we will see how to perform the entire process with the VMware ESXi hypervisor logs, treat them with Elastic Stack and finally visualize in Grafana what interests us, such as error logs, Incorrect sign-ins…
¡Ole, ole and ole Rigodón! VMware through a fling presents a new version of the ESXi hypervisor, for ARM architectures, What a marvel! In this post we will see something that is not supported (For now), and it's nothing more than how to install ESXi on a Raspberry Pi 4. ¿For what? Then we discussed it.
This is the first document in a series of posts where we will look at how to perfectly deploy and configure a VMware vSphere platform 6.5, in this document we will look at the simple installation of the ESXi hypervisor, plus a brief walk through its basic configuration with the DCUI and we will access your Host Client to manage it as well as your virtual machines. We will continue with other documents that will make us grow and optimize our environment!
In this document, we'll look at all the steps needed to be able to monitor an ESXi host, we will see the most common parameters and the values that we can obtain to have a controlled environment thanks to Nagios and Centreon! All the information we can obtain is amazing! In other documents we will see other information that we can obtain from vCenter and its VMs, Today the hosts are playing!
The other day I was reading a healthy debate between fellow bloggers on LinkedIn, And it's true, few of us think of programming certain curious tasks such as this one. While it's interesting to back up our ESXi setup… Why don't we schedule it? I leave you a couple of options that will surely fit you to have updated backups of the ESXi configuration.
In this document, we'll look at an easy way to upgrade a VMware ESXi host to the new version 6, We will upgrade the host in-place, First with the local media (DVD/USB) and graphic installation, then using CLI remotely with the depot file and we will finalize the document seeing how to revert the update if necessary!
If we need to set up a lab or need to test any new configuration before applying it to our customers' hosts, we will be able to virtualize VMware ESXi 5 and run virtual machines under these virtual hosts. In this document we will see how to dispose of this, in addition to being able to configure an EVC cluster with virtual hosts to be able to mount Storage Appliance or whatever we need,
Once our hosts have been configured, it is advisable to keep a backup copy of their configuration, an easy way to back up the entire configuration of an ESXi host is by using the VMware vMA appliance or by using the VMware vSphere CLI (vCLI). Once we have the backup, we can restore it if necessary in a simple way, we will also see another command to reset ESXi hosts to factory values.
ghettoVCB.sh is one of the few good scripts I know that can help us make copies of our VMware environment for free, This is, we will be able to make backups on both ESX and ESXi servers without a license! We can say that it behaves the same as the traditional VCB, Takes a snapshot of the virtual machine to be copied, It copies the virtual machine's files to a directory and then deletes the snapshot. ghettoVCB is a script that must be run on the VMware ESX server itself(i), we can schedule it to run using 'Cron’ or as in my case I will run it from a remote computer using the utility plink.exe. In addition, ghettoVCB stores backups in an ESX datastore(i), In this document we will see at the end how to make the backup in a Windows folder that we have thanks to NFS.
