Troubleshooting Icinga Notifications

I don’t really know the reason behind it, maybe because the typical scenario for notifications is just “send all events to this mailing list”, or as we say: set it and forget it. But we shouldn’t use this as an excuse: monitoring projects now consist of tens of thousands of objects (hosts plus services), and…

Upgrading to the New nep-setup on NetEye 4.31

After a first semester full of great opportunities (many colleagues like to say so), the wheels have started turning again for NetEye Extension Packs. Now, a big evolution is beginning: in the near future, NEP will encompass the entire NetEye infrastructure, meaning it will also configure and manage NetEye Satellites. To do so, the current…

Finding Subtle Changes in your NetEye 4 Monitoring during Critical Activities

Rules and standards are important. In a world based on collaboration, following a well defined behavior is key for avoiding errors based on some sort of misunderstanding. This is also true for the world of information technology: someone releases software that is incomplete by design, and then leaves the completion of it to the people…

Strategies for Secret Management

In my previous blog post, we had a long discussion about how Icinga 2 manages its configuration in a Distributed Monitoring environment and how this can lead to unwanted disclosure of sensitive data, be it Secrets or Personal Data. The post ended with a set of recommendations/best practices that can be summarized in the statement…

Secret Management with NetEye Monitoring

Today I want to talk about a topic that, although it is (and always has to be) in the spotlight, is seeing its popularity skyrocket even more in recent months: how to handle Secrets and Personal Data with NetEye. And I’m not talking about the right way to use Director’s Data Fields, how to hide…

Hosts, Zones and Broken Icinga 2 Configurations

During 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…

Metrics on NetEye Monitoring

(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…

Understanding Instability in a Monitored Environment

Whenever a new monitoring project gets underway, a consultant discusses with the customer about almost any related topic: what needs to be monitored, how to monitor it, when to implement it, how to represent performance data, etc. Based on customer needs and desires, any sort of implementation strategy can be planned, but almost all of…

Monitoring Certificate Expiration with the x509 Module

Now, if you’ve followed my previous blogs about the x509 Module, you should have in place your x509 Certificates Asset with (or without) a minimum of cleanup routines. Now it’s time to look at what Icinga was made for: monitoring. Making an asset out of all of your SSL Certificates is only half the job….

Cleaning up Your Certificate Inventory

Some of my customers make use of short-expiration SSL Certificates signed by Let’s Encrypt or similar services. Our company also makes extensive use of this kind of certificate, and in the near future most (if not all) of your SSL Certificates will in any event become like them as their expiration date approaches. Maybe some…

Certificate Inventory and Monitoring with NetEye

In the last 10-or-so years, the complexity of enterprise IT applications has greatly increased: each of them can span vertically with multiple (and complex) layers, and each layer can serve applications other than the one that it’s part of. And, obviously, each layer spans across several servers to increase performance and availability. This inevitably leads…

Understand Which Agents you Need to Upgrade

As you may already know, starting with version 4.12 NetEye 4 upgraded its Icinga 2 engine from version 2.10.5 to version 2.11.3. At every training session, I always emphasize this rule: Icinga 2 Master Instance version >= Icinga 2 Satellite Instance version >= Icinga 2 Agent Instance version And thus everyone expects that his or…
