Monitoring systems acquire information from various devices in different ways: API, SNMP, syslog, etc. One of the most important methods in Icinga-based systems like NetEye is the Icinga Agent. This agent is installed on each server and collects and sends information to the master NetEye node using secure protocols. When we work within a small…
Read MoreIn my time at Wuerth Phoenix I’ve worked on upgrading the customactions and ondutymanager neteye modules, as well as developing a new module called AIA, which stands for Alert Interval Adjustment. In this blog post I’ll talk about the AIA module. The Pitch Suppose you’re a large company with a vast and complex IT infrastructure….
Read MoreDesired State Configuration (DSC) is a feature in Powershell 4.0 and above that helps administrators to automate the configuration of Windows. I’ll show you below how to use it in order to maintain a consistent Icinga agent configuration across your Windows servers. Our use case As an admin I would like to distribute and configure the…
Read MoreDuring my experience as a Würth Phoenix consultant, I’ve seen a pretty long list of broken Icinga 2 configurations. Several times, customers have begun a scheduled meeting with something like “Hey mister consultant, ever since the last deploy some objects have stopped being monitored, but I don’t see any errors!”. After some troubleshooting, everything always…
Read MoreWe were recently asked how to dynamically monitor folders with Icinga. Several of our clients monitor folders whose names change from day to day. For example, suppose every day I want to see if there is a file named with the date of that particular day, or I’d like to see if there is a…
Read MoreIn my second and last blog I want to talk about the procedure for writing Icinga Web 2 modules (icingaweb2-modules) for NetEye. This will be my last blog because as of today, I will sadly leave this company. In my short time here I’ve had the occasion to learn the art of making own Icinga…
Read MoreIn recent months many enterprise customers have asked me for a solution to create services on their monitored Icinga hosts automatically. They want a single point of insertion (like a list) for all services on the host as well as for the NetEye system to do all the work managing their creation and deletion. How…
Read MoreDuring migrations from NetEye 3 to NetEye 4, I often run into really outdated monitoring checks in the Windows world, where the last update was more than 10 years ago… and whose logic is therefore now completely obsolete! The time for change is now!!! In the last year Icinga released a really interesting project that…
Read MoreIn my first blog I’d like to talk about a common process in the life of everyone who manages their monitoring system daily, along with an approach to improving it with a new module for Icinga Web 2 named Custom Actions, which we recently implemented for one of our clients. The process of scheduling downtimes…
Read MoreAs a NetEye user I might want to install a Remote Host Agent that belongs to a Zone that can’t communicate directly with the Master. So to be able to do this, we decided to use Tornado and NATS. Linking with Patrick’s article in this article I’ll explain how to configure them. What we want…
Read MoreWhen implementing monitoring with Icinga2 you will soon reach the point where you will have to install Agents in order to monitor your infrastructure in-depth. Here the Icinga2 Agent provides concepts to access information about and the properties of an operating system over a secure remote connection. In an enterprise environment consisting of thousands of…
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 MoreIn the last few weeks, we collaborated with the Icinga2 developers to create a new powerful API, called “Execute Command“. The main purpose of this new API is to execute specific commands on a node by sending the request to the parent node. This is useful when the user cannot reach the desired node (an…
Read MoreNetEye4 provides the Icinga Template Library and includes several plugins ready for use. The Icinga Template Library (ITL) implements standard templates and object definitions which allows for the very quick and effective use of plugins. These definitions are read-only and available through the Icinga Director > Commands > External Commands menu. Most of the plugins…
Read MoreThe Tornado module is improving release after release. With NetEye 4.12 we reached one of our main goals: Tornado is now configurable within the graphical interface, and you can now create new nodes and rules, or edit and delete your existing ones. The icingaweb2-module-tornado module (i.e., the graphical interface of the well-known Tornado module) is…
