Updating Hosts with vSphere Update Manager 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!

Integrating vCenter Server Appliance 6.5 and its ESXi hosts in Active Directory

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'.

NAKIVO Backup and Replication 7.3

I wanted to tell you that NAKIVO has just released its new version of the backup and replication solution for virtual environments! The New NAKIVO Backup and Replication 7.3 It allows, among other new features, to make backups from storage arrays with deduplication, increasing the speed of the VM backup up to 53 More times!

Deploying VMware vCenter Server Appliance 6.5

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!

Monitoring thanks to snmpwalk

Continuing with documents on Nagios or Centreon, Let's go with a post that may be in common use, above all, when we need to monitor something by SNMP and the Internet gurus have not developed a script that we need. We will see then, how to query over SNMP what a device might 'spit out'’ Thanks to SNMPWALK and then we will monitor it! And at the end of the document we'll look at how to monitor the traffic of any network device that has SNMP enabled as well!

Installing VMware ESXi 6.5 + DCUI + Host Client

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!

Getting data from our Xiaomi Smart Scale with Raspberry Pi

If you have the Xiaomi Smart Scale scale, follow the steps in this document and you will be able to read your weight from a Raspberry Pi, by connecting via bluetooth we will store the records in a MySQL database, and so if we want we can exploit them super easily with Grafana! I will leave you with a series of documents that I think are very interesting to obtain information from different devices that control our life and visualize it in a super cool way!

Nagios – Monitoring our VMware vSphere VMs

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…

Setting up corrective actions in Centreon

Another of the great advantages of having our monitored platform is that we can take advantage of and generate our own scripts to carry out corrective actions in our environment. Something that runs on the remote machine when we have a problem, for example if we run out of disk space, Well, a script that releases temporary, or the example that we will make in this document; when Nagios or Centreon detects that we have DNS Service from the DNS Server down, Well, let him start 🙂 it Ideal for any need we have, repetitive problems that we can automate their solution…

Nagios – Monitoring Citrix NetScaler

Continuing a little with Citrix elements that we can monitor… what less than our NetScaler! In this document, we'll see how to monitor a Citrix NetScaler VPX virtual appliance that is currently the Gateway for my Citrix XenDesktop organization. We will monitor its basic consumption such as CPU through SNMP, Memory or disks, but also the connections, your network interfaces or certificates!
