Scenario NetEye 4 is a comprehensive monitoring platform which natively supports Business Processes. A Business Process is an abstract view of a customer’s Business from the Application point of view. Usually, it’s a collection of Icinga2 checks aggregated by “AND, OR, At Least” logics in order to monitor if a Business Application is really available…

Several Icinga 2 checks support an historical view of the status. An example is the firewall interface performance status below, which displays a Performance Graph: Getting a better overview All the graph data generated by the…

Read MoreIn 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…
Read MoreToday 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…
Read MoreToday my objective is to collect the performance metrics from various NetEye Icinga checks and write them out to Elasticsearch so I can apply Machine Learning (ML) algorithms to identify potential anomalies. This is a task that’s not possible with the open-source version of InfluxDB installed in NetEye. Moreover, this data in Elastic is used…
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 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 MoreRecently I was asked why alerting in a NetEye 4 environment isn’t run via the central master, but instead via the satellites. The background to this is that the NetEye Master is located in Italy, which controls various satellites in other European and African countries. It’s therefore a strategic decision that alarms are sent from…
Read MoreVeeam is a widely used and well-known backup system. A customer recently asked me if he could check on the operation of his Veeam-based backup system by verifying the Windows event log, since the standard checks used within the community did not provide him with the current status of his Veeam infrastructure. This use case…
Read MoreIn Würth Phoenix we usually organize a workshop with the Icinga2 team twice a year. These workshops are an opportunity for all participants to show the latest developments, propose new ideas and explore new solutions. They’re always very inspiring days with an incredible flow of ideas and a lot of code written. During this year’s…
Read MoreA frequent request I get is how to view the availability of hosts and/or services within a Grafana dashboard. Here I demonstrate how to do this for host availability. To implement this, we first create a new table in our MariaDB on NetEye. I’ll call this table host_daily_sla and put it in the pre-existing reporting…
Read MoreWith the new NetEye 4.17 release, we’ve introduced a new feature: Smart Director. What is Smart Director? Smart Director is an extension of IcingaWeb2’s Director module that allows an operator to immediately deploy host and service changes without executing the classic Director deployment. Why another Director? The NetEye team implemented this fantastic feature to meet…
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 MoreLast week I had to implement monitoring checks for a customer’s host running an IBM iSeries server. As the monitoring for that is a bit particular, I’d like to share what I did, and also share with you an Icinga2 Basket containing the monitoring structure. Where to Find the Necessary Files You may download the…
