Single Node

NetEye can be run on a Single Node Architecture, i.e. as a self-contained server. Single Node is the basic variation of NetEye setup, and is aimed at small environments that require limited resources. Apart from that, running NetEye on a Single Node architecture is applicable in case your infrastructure does not require high availability. To maintain high availability of a monitoring environment, you should better consider going with Cluster setup.

To start monitoring on a Single Node it only requires to install NetEye, run initial configuration, and begin the actual process: define services, hosts, etc.

A variety of NetEye services may be run on a Single Node installation to fulfill monitoring functionality.

Single Node is a basic setup type, however you can enhance your monitoring environment to a NetEye Cluster and/or set up several tenants to monitor simultaneously. To fulfil the latter, your environment might use Satellite nodes as actors that help communicate data to the Master. Satellite Node is to be set up together with a Single Node, and then configured individually.

NetEye services on a NetEye Single Node installation are managed by systemd. A single systemd target is a special systemd unit and is responsible for managing start and stop operations of NetEye services.

There can be more than one systemd unit available within installation, however only one may be enabled. To find out which NetEye systemd target is currently active, use the following command.

neteye# systemctl list-units "neteye*.target"
