In today’s critical IT environments, setting up a cluster represents a common approach to increasing the availability of services and applications. The concept of clustering is a set of independent computers that work together, where if one node fails another node automatically begins to provide services through a process known as failover. To make sure…

Read MoreRemote Desktop Services 2016: The AppContainer Windows Server 2016 introduced the “AppContainer”, which is created when users connect to the server for the first time. Due to a registry leak, the Windows Server generates registry bloat for firewall rules. This registry bloat can be found in the following registry keys: HKLM\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\FirewallRules HKLM\System\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\RestrictedServices\Configurable\System Over time, this…
Read MoreHistorically, NetEye Clusters were configured with DRBD as Master/Slave resources. This led to the following rather cumbersome resource configuration for an N-node cluster: $SERVICE_drbd_master ( x 1 ) $SERVICE_drbd_master_clone ( x N ) $SERVICE_drbd_fs $SERVICE_virt_ip $SERVICE Note: $SERVICE serves as a placeholder for any Cluster Service running in NetEye 4. At least ten constraints were…

Read MoreAs already mentioned in my other blog posts, NetEye 4 is based on Icinga Web 2, a powerful PHP framework. During the development of some of our custom NetEye modules for Icinga Web 2, we needed to include some new, custom jQuery plugins to create a neat new effect in the GUI. For example, with…
Read MoreInfrastructures get reorganized, organizations grow and naming conventions change. Icinga2 nodes can reliably trust each other by following the guidelines for certificate generation and building a dedicated certificate chain. Certificates rely on hostnames and DNS, which aren’t usually subject to changes, but it does happen sometimes. What then? First of all, all certificates in NetEye’s…
Read MoreRemote Desktop Services (RDS) Performance In a complex distributed RDS environment, it’s difficult to measure RDS performance: the end user typically notices responsiveness in a different way compared to measuring a single Windows Performance Counter! Overall performance tends to degrade over time: and frequent maintenance is required to keep an RDS Farm efficient. Of course,…
