Today I want to present an Icinga 2-based monitoring use case where concepts of the powerful Icinga 2 DSL functional language come into play. The use case is based on mapping the status of a Host/Service Object via passive check results only. For this kind of use case, any accidental active status check could potentially…
Read MoreDirector is one of the most important modules in NetEye 4 because it’s used for managing, automating and deploying the configurations of all monitored objects. In all our projects we use automation in Director: through the Import and Synchronization rules we can automate many operations such as the import and synchronization of hosts, service checks,…
Read MoreThe performance graphs present in NetEye are very useful for getting an immediate idea of the trend related to a service check, but they’re still limited to the metric being viewed. Also, the “Show all graphs” option available from the Actions menu of each monitored Host can have different usage limits due to the presence…

Read More(Or, Who’s Monitoring the Monitor?) Everyone uses a monitoring system to understand what’s going on in their own environment and how it performs, but what about the monitoring system itself? The monitoring system also has its own tasks to perform, and obviously its own needs. Therefore even NetEye itself, while performing its duties, can be…
Read MoreSOAP is a messaging protocol for exchanging information based on XML over the network. SOAP messages are written in XML, which is why they are platform- and language-independent. A lot of enterprises have such webservices that return useful data for use in (web) applications. Now, if you want your application to work, then these webservices…
Read MoreSince the introduction of Satellites in NetEye 4.19 one of the most frequently asked questions has been how CAs and Certificates work on Satellites. In this short blog post I’ll try to answer this question. First of all a bit of introduction about Satellites. A Satellite is a NetEye machine connected to a Master, which…
Read MoreIn 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…
Read MoreThis article explains how to set up a NetEye4 satellite using a Raspberry Pi. This is not an official guide and this solution is not officially supported. As test-bed I used a Raspberry Pi 4B with 4GB of ram, 32GB microSD card and NetEye 4.12 single-node installation as master. Master Configuration Add a new zone…
Read MoreBetween one trial run and another, in these summer days I’ve also taken my time to deepen the theme on the interaction between NetEye 4 and ticketing systems. For my tests I chose the Jira Service Desk Cloud, and I must honestly say that the result achieved was satisfactory 🙂 As a method of integration…
Read MoreNetEye 4, thanks to the Director module, offers very powerful mechanisms when it comes to fetching data from external data sources. Among the external resources that can be configured in NetEye 4 there is clearly LDAP / Active Directory. This type of resource can be used for multiple purposes: Authentication of users Import of LDAP…

Create a Telegram Bot A very easy way to create a bot on Telegram is through … another bot 😉 BotFather is a Telegram bot dedicated to the creation…
Read MoreScheduling downtime is extremely useful, if not essential, for the correct management of a monitoring system. What exactly is downtime and what is the reason for having it? “Downtime can be scheduled for planned server maintenance or any other targeted service outage you are aware of in advance. Downtime suppresses notifications and can trigger other…
Read MoreThe 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…
Read MoreWe are witnessing a deep transformation within the NetEye 4 core: Icinga Web 2 will move from the Zend Framework to a totally new library called IPL (Icinga PHP Library). This change is already underway in the NetEye 4.3 release with the new version of the Director module. The Icinga team has already partially introduced…
