If we have a vCenter Server Appliance or more commonly known as vCSA server in our organization and we want to know the status of its health and the service it offers… What are we waiting for? In this post you will see all the necessary steps to have the vCSA server fully monitored!
If we want to protect our vCenter Server service, that we know every day is more important; we will be able to take advantage of one of the new features of vSphere 6.5, what is having the vCSA appliance in high availability. In this document, all the steps required to deploy and have HA-protected vCenter Server with VMware vCenter Server High Availability.
Continuing with the series of posts on vSphere 6.5, in this document we will be able to see another of the novelties that VMware vSphere brought us with its version 6.5, which is nothing more than the possibility of backing up our vCenter Server! In this post, we'll look at how to set up your backup and make backups and we'll also look at how to recover a vCenter Server Appliance if necessary! I hope you enjoy it!
To be able to manage certificates in vSphere 6.5, we'll see how to use the tool we have to manage the vCenter Server Certificate Authority. We must make the CA that brings the PSC a subordinate entity of our own CA of the domain and generate certificates in which we do trust and so not even the browsers will trust and other dependencies. At the end of the document, we'll look at how to change ESXi and vCenter certificates.
We will be able to continue with another automatic update process, and it is only once we have all the hosts updated to the version 6.5, We will need to update (in this order) VMware Tools and Virtual Machine Hardware. The latter perhaps more optional. We will do all this through Update Manager which, as we know, is embedded in the vCenter Server Appliance 6.5
As we already know, Update Manager is the VMware product that will keep the vSphere virtual infrastructure fully up to date. With UM we will be able to update the patches or versioning of ESXi hosts in a centralized and fully manageable way, as well as Virtual Machines or Virtual Appliances! We will see as an example how to update a host of the version 6.0 from ESXi to the 6.5 Update 1, for this, without moving from the chair, we will upload an ESXi image to Update Manager and install it to the hosts that need it!
In this post we will be able to see how to configure authentication against our Active Directory in the VMware vSphere virtual platform. We'll enable it on the vCenter Server Appliance and ESXi hosts, so that you can assign access permissions to Active Directory users or groups. And so instead of using the default credentials (As we do wrongly); each employee will use their DA account, with the privileges that he should have, It will also be useful to see 'Who does what'.
In this post you will learn how to deploy a VMware vCenter Server Appliance 6.5, By following the steps in this document, you will be able to have a vCenter server deployed on a Linux appliance in a virtual machine to manage your vSphere infrastructure, both hosts and VMs! It is a second basic document in a series of articles to come! I hope that if it is not in this, The next documents will be useful to you!
In this document we will monitor interesting elements that we will obtain from our VMware vSphere-based virtual machines, centralizing in Nagios the checks we do to manage its values, Get alerts or generate graphs of your consumption. We will see, among other checks, in the VMs obtaining the values of their CPU Ready, CPU Wait, Memory Overhead, Memctl, Balloning, Write or read IOs…
In this post we will see how Nagios can help us monitor the existence of snapshots in our virtual infrastructure, Everyone knows the danger of having snapshots or leaving them for long periods… Hanging backups that leave half-baked snapshots… To combat this, We'll automate a periodic check-in with a great script!
