The NagVis module: Adding a Grafana Panel on Mouse-over

Hi everyone, in this article I want to tell you about the NagVis module and how we’re going to customize a template so that it can allow us to modify the information displayed during mouse-over (hover). Basically, what we’ll try to achieve will be to preview the performance graphs written on Influx via an additional…

Monitoring with Your Own Icinga DSL Script

In this article I’ll talk about Icinga DSL and how it can be extremely useful if you want to compute thresholds. Our goal today is to be able to change certain monitoring thresholds when some parameters change. Example The example I propose is the following: I’m a system administrator, and I would like the warning…

ITSM Ticketing Integration with NetEye

Increasingly often, monitoring tools are the recipients of the notifications that are sent when problems arise, in order to guarantee the resolution of those problems quickly. In some circumstances, we need to extend the default type of communication that has historically been used: email. In this blog post I will describe how we integrated NetEye…

Take Care of Your Data: InfluxDB Sanitization

InfluxDB is the database used in NetEye for saving performance data. It guarantees graphic visibility of the data (thanks to the Grafana frontend) and it is very important that the data stored is useful. I’ll give you an example of how simple it can be to produce obsolete data in Influx: Suppose I create a…

Burstable Billing Bandwidth Using NetEye

Within Internet provider companies, very often we are asked to calculate the amount of Internet bandwidth in order to bill any excess use of bandwidth to each customer. We decided to make this calculation completely customizable using NetEye together with the built-in tools Icinga2, InfluxDB and Grafana. Phase 1 Using an SNMP check, we measure…

NetEye and Predictive Monitoring

We often hear about predictive monitoring, alongside the words machine learning and anomaly detection. Today, just as in the past, the “data” is invaluable and what we will try to do here is use simple data we can easily collect (data which individually might have no value) and apply Machine Learning techniques in order to identify anomalies, and then…

A Simple Way to Deploy Linux Agents Using the Icinga 2 API

The Agent’s distribution is probably one of those more time-consuming tasks. This can be for various reasons: different operating systems, network segregation, administrative credentials that are difficult to obtain, or even more simply, a large number of Agents to install. We know that the Agent installation on Windows servers is made easier by this PowerShell…

Segregated Multitenancy Monitoring: The Satellite and the Essential Role of the CA-Proxy

In many circumstances, monitoring systems need to be extended to locations where we have no direct control. We can think for instance of a company that provides monitoring services to various customers: each with its own firewalls and each with its own security rules. The deployment of firewall rules from the central monitoring node to…
