Because of its open source nature, NetEye 4 combines loads of different technologies, which makes it impossible to identify “the” NetEye 4 Tech Stack. Based on RHEL/CentOS 7, most of the user-facing parts are written in, or at least proxied through, PHP, whereas there is no real common denominator for other backend services. This looks…
Read MoreWhen designing complex systems with a multitude of services, more often than not some of them logically form loosely coupled units. Usually these services should remain independent to a degree, i.e. free to be started or stopped independently. However, we also wanted a mechanism to command the loosely coupled unit as a whole. Sometimes however…
Read MoreTornado is the spiritual successor of the NetEye EventHandler. Tornado is an open-source, rule based Event Processing engine designed to handle up to millions of events per second. We can leverage this capability to ingest all possibly interesting events of our entire infrastructure, and react to the effectively interesting ones. In this blog post we…

Read MoreTornado is the spiritual successor of the NetEye EventHandler. As such, we took inspiration from its limitations, picking the most interesting ones, and trying to optimize for these scenarios. One example of this is the Processing Tree. In the past, all rules had to be placed in one of four predetermined groups, and events ran…

Read MoreAs soon as you manage more than a few DRBD resources distributed over a wide set of hardware, split brain situations cannot always be avoided. Standard split brains are caused by multiple nodes having different opinions about the latest state of the data on their local disk. Disclaimer: If applied incorrectly, commands in this blog…

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…
