Introduction

NetEye is a flexible stack of monitoring technologies and can easily be adjusted to serve its purpose under conditions granted by the hosting infrastructure.

NetEye is a scalable and extensible software. Indeed, on the one side, NetEye can be run on a Single Node or Cluster (multiple nodes) architecture, while on the other side you can add Tenants, Satellites or even agents to gather data and send them to the Master for processing, offloading tasks to other devices.

Based on the customer’s monitoring and analytical needs, services can be executed in complex environments across multiple locations, e.g. tracking the state of routers in all the premises and offices of your organization.

A set of services provided by the NetEye may vary depending on whether you choose to utilize core functionality modules that are originally shipped with NetEye, or install additional components in order to perform even more specific tasks, e.g. measure visual end-user experience with the help of the integrated Alyvix software.

Single Node and Cluster Concept

Another decisive point while tuning the NetEye architecture to meet your business requirements is the complexity of the processes to be executed.

All the provided services may be scaled by means of adopting an appropriate NetEye setup type. To choose the most appropriate setup type you will need to estimate the expected level of the monitoring system and the amount of resources you’d like to involve in the monitoring process.

In case your target infrastructure is small and requires a minimum amount of resources, running NetEye on a Single Node architecture would be the best solution.

For a more complex environment that requires redundancy and high availability when running monitoring process, it is recommended that you use Cluster setup. Cluster allows to scale the system up to a level where it is able to deal with an extensive amount of resources. At the same time Cluster grants high-availability and helps to avoid any downtime or service disruption whenever one of several nodes in a Cluster goes offline, e.g. in case of a networking or hardware/software issue.

NetEye Master and Multi-tenancy

NetEye Master instance serves either as a self-contained server (Single Node), or a high availability Cluster composed of a combination of nodes.

The Master allows to build individual and isolated communications from multiple clients to a centralized server, i.e. the Master, that will then process independently all data streams (see NetEye Master and Multi-tenancy).

Communication between the client and the Master may involve Satellite nodes. Each client is to be monitored independently, so a Satellite would be assigned to each separate set of hosts to collect and communicate their data to the Master for further processing.

Satellites can be set up irrespective of whether you are using NetEye as a Single Node or a Cluster.

The client data may also be transmitted to the Master directly, without involving a Satellite (or multiple Satellites where appropriate) as an actor.

Having received the data, the Master then processes it in order to fulfill predefined tasks, e.g. make data entries to Influx DB, generate a Tornado action based on the event, etc.

NetEye supports multi-tenancy architecture, where a single NetEye instance allows you to serve multiple business units inside your organization(s). Multi-tenancy concept allows you to monitor a number of clients, whether you choose to run monitoring on a Cluster or Single Node architecture.

Having multiple tenants you will be able to aggregate even larger arrays of data, preserving data security: each tenant zone communicates with the Master individually and is not visible for others. Communication of a tenant with the Master can be protected by using multiple accounts.
