Requirements for a Node

This section lists hardware and hypervisor requirements to install NetEye. The system requirement are intended for a Single Node, a Satellite Node, and each Cluster Node, and for both physical and virtual installations.

System Requirements

Table 1 gives an overview of the basic system requirements for a Node in both a testing and a production environment. Depending on the services activated and the load on the system, requirements might need to be raised. Indeed, running resource-intensive services like the SIEM or ITOA would require to increase all the requirements. Moreover, also disk space may become an issue when the amount of logs produced by a NetEye installation, by its monitored objects, or by both is large.

You can always contact the official channels–sales, consultants, or support portal– for advices on how to tailor the system according to the needs.

Starting from version 4.23, NetEye is based on RHEL8, which requires a license that is provided by NetEye sales or consultants. Since this license is necessary to launch neteye install during the installation procedure, make sure you have it before starting the installation.

If your NetEye Node does not have direct access to Internet and needs instead to pass through a proxy to reach the Internet, then you need to configure the software running on NetEye to pass through this proxy, as explained in Section Nodes behind a Proxy.

Moreover, the following domains must be reachable from each Node, to allow for updates and licence verification:

Supported Virtualization Environments

NetEye installation is supported in the following virtualization environments. For each one are listed some options that need to he configured during installation.

  • VMware. Select as ESXi 6.7 and Later as Compatibility, then VMware Paravirtual as SCSI controller, and finally either SATA or SCSI.

  • KVM. In Boot Options check that Disk1 and CDRom are both selected, then change the disk bus to SATA (VirIO Disk 1 under Advanced options in the next configuration step).

  • HyperV. No particular option is required.

LDAP Access Requirements

NetEye 4 is using LDAP protocol for the purpose of binding users within Active Directory, OpenLDAP, to a centralized account. Hence, NetEye adheres to the LDAP Standards Track.

In order to log in to NetEye 4 with a centralized account, create an LDAP/AD user with read permissions on the following objects:

  • Account name

  • Password

  • Email address

You will also need to open several TCP ports from NetEye 4 to the LDAP system directory.

Notification Requirements

Notifications can be sent via SMTP or SMS, therefore the following requirements should be satisfied.

  • To send notifications via SMTP you need an SMTP Relay Server, which should be reachable by NetEye Nodes as described here

  • In order to send SMS messages, unset the PIN on your SIM card

    • To handle SMS we provide two types of modem:
