Monitoring a cluster from Centreon
Surely more than one of us has some service in clustering, but, How do we monitor this with Centreon?? That is, Know that the cluster offers its service because its members offer it.

Configuring VMware vCenter Server High Availability
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.
Citrix Netscaler in HA
Very good, I leave you a Post by the great Oscar Mas, one of the great Citrix & Shoring, Enjoy: Today I'm going to show you how to set up a NetScaler system in High Availability (HAS), Performing the configuration by console. We start from the base of two NetScaler servers, which one of them is fully configured (netscaler1.ilba.cat). The first thing we will do is link the two NetScalers and then join them, so that in the event of a fall of one of the two, the other continues to work.
Citrix Provisioning Server in High Availability
In this document, we'll look at how to extend a Citrix Provisioning Server infrastructure for high availability, this critical service that distributes OS to desktops or servers, expanding capacities and therefore having greater performance! It is a very simple task that we will have to perform if we have this service in production to quickly deploy operating systems over the network through PXE!
High Availability with Citrix NetScaler
In this document we will see something fundamental in environments where we must have a system always available, where NetScaler is the main element by having several balanced and protected external services. In this case, we will see how to configure an HA or a NetScaler cluster so that under no circumstances can we drop the services that we publish with our appliances.
Citrix StoreFront Server Pool for HA
If we want to provide our Citrix environment with high availability, we will see in this document how to do it at the StoreFront server level 2.5, where we will create a group of two servers that will have the same configuration, Later, using other alternatives, we will configure a balance of access to them.
Using VMware FT
Another new feature of VMware vSphere 4 is the ability to use Fault Tolerance or FT. It is the ability to have real high availability, This is, with previous versions of VMware, we had DRS, that if a physical host went down, the virtual machines running on it, they run on another host, Foresaw a restart of the virtual machines. What VMware FT gives us is the possibility that virtual machines do not have to be restarted, and in case of ESX host crash with virtual machines, those that are protected with FT will continue to run on another host without loss of service.
