NEP Common

The nep-common package is the core of NEP Design and the starting point for a new NetEye setup. It provides the minimum requirements to implement a basic monitoring of remote systems and to display their status. With nep-common it is possible to perform standard monitoring of:

  • Windows-based servers and clients through the Icinga 2 Agent

  • Linux-based servers and clients through the Icinga 2 Agent

Using the provided objects, is also possible to:

  • Perform basic SNMP monitoring (by querying SNMP devices for specific OIDs)

  • Prepare a common base for passive monitoring

  • Represent Objects that are not strictly related to a server or its services

Minimum supported environment

This package can be installed on systems running the software described below. Systems with equivalent components are also suitable for installation.

Package requirements

ITOA Dashboards shipped with the``nep-common`` package require Icinga 2 features influxdb and ido-mysql fully configured and running. Data provided by these two features must be accessible from Grafana using two dedicated Data Sources:

  • A Data Source named icinga2-influxdb able to access data from the influxdb feature

  • A Data Source named icinga-mysql able to access data from the ido-mysql feature

Data Source icinga2-influxdb is available by default on NetEye. If you cannot find it, please read the Grafana Official Documentation for InfluxDB Data Source and create the appropriate Data Source manually.

Data Source icinga-mysql must be created manually. On a NetEye environment, this Data Source is automatically created by the setup routine. On other systems, please create it manually. To get more information about Data Source creation, please read the Grafana Official Documentation for MySQL Data Source.

Setup instructions

If all requirements are met, you can now install this package. To manually set up the nep-common package, follow the instructions contained in manual-setup.md located in the root directory of the package.

Available Objects

This section contains a description of all the Objects from this package that can be used to build your own monitoring environment.

Director Objects

Director Objects are Objects created (or imported) into Icinga Director. This package contains the following Director Objects:

Data Lists The following Data Lists can be freely customized by the End User. Their purpose is to provide easy data filling to better describe the monitoring environment.

Datalist name

Description

[NX] Application List

Service Templates

The following Service Templates can be used to freely create Service Objects, Service Apply Rules or Service Sets. Remember to not edit these Service Templates because they will be restored/updated at the next NEP Package update.
