During one of my last sessions with a customer I had to deal with a very particular use case, where I couldn’t use the solution presented in my previous blog post (https://www.neteye-blog.com/2025/08/massive-update-of-the-icinga-custom_var-host-services/). In this new scenario, the customer wanted to clean up a custom_var linked to a service, whose value, inherited from the host, had…
Read MoreOne feature that’s widely used by customers for the enrichment of entities (hosts/services) within Icinga is custom_var. These can be used for a variety of reasons: to provide more information to end users about a device, faster classification, to integrate data used by other tools such as notification, etc… These variables can be managed directly…
Read MoreThis article describes an ad-hoc monitoring solution for MSSQL within a synchronized high-availability setup. Due to the circumstances surrounding the request from a customers’ request, with this setup we couldn’t use the standard command/check that’ are’s commonly used, but an additional layer was required to manage the resources involved. Use Case The behavior of MSSQL…
Read MoreAfter developing a custom check for monitoring the most CPU demanding processes on Windows servers, we implemented a similar check for RAM usage. Like I described in that previous post, we built this command via PowerShell. PowerShell provides the cmdlet: Get-Counter that gets performance counter data directly from the performance monitoring instrumentation in the Windows…
Read MoreDuring my last session with a customer, I faced an interesting and challenging issue in the Windows environment. The question was: “How can I monitor the list of the most CPU-demanding processes?” The request immediately looked like one that’s very simple to understand, but hard to implement. We look for something out of the box…
Read MoreThis article stems from a project on the remote control of devices using NagVis maps. The main purpose is to find an easy way to actuate a remote device through a click on an interface. To do this, we implemented a method that uses Nagvis’ context menu by adding links. Clicking on them sends a…
Read MoreSome years ago, one of my colleagues wrote an article about how to “Avoid Tornado Rules Repetition with a Map Post-modifier”. He presented an interesting and very useful way for creating Tornado rules without rewriting them. The core of his approach was based on the Mapping modifier, a functionality in the previous Tornado GUI that…
Read MoreCustom Variables are widely used in the NetEye 4 (Icinga) monitoring system in order to tag/add information to a host/service. In order to speed up setting these variables, users use the inheritance mechanism to inherit them from parent objects (i.e. hosts). This feature is very useful, but sometimes it can create some doubt about what…
Read MoreMonitoring 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 MoreTornado is a CEP “Complex Event Processor” that receives reports of events from data sources such as monitoring and email, matches them against preconfigured rules, and executes the actions associated with those rules. Some vendors provide static notification systems that cannot be customized. For example, during one project we were faced with a tool that…
Read MoreCommvault software is an enterprise-level data platform used to back up, restore, archive, replicate, and search data. The software is available across cloud and on-premises environments, and a lot of customers are using this solution as part of their infrastructure. And in such situations the necessity arises to develop a solution for integrating COMMVAULT information…
Read MoreIntroduction In this article I’ll introduce a feature that some customers have frequently asked for. The customers’ request is linked to the fact that automation (whether via Tornado, ad-hoc scripts, etc.) generate a lot of services “on the fly”, for example as shown in my previous blog post. These services are created, updated and eventually…
Read MoreIntroduction As introduced in a previous post, Cisco’s APIC is a core component for several of our customers; it’s a complex solution that every user can employ to fully customize their configuration. There I explained how to monitor the APIC at a high level, summarizing the fault information tenant by tenant. Some customers needed to…
Read MoreUPSs are critical devices that need particular attention when you’re monitoring them. Most of them are not very performant with respect to SMNP requests you send them. For this reason, passive monitoring via SNMP traps is the best solution. In this way, monitoring doesn’t burden the hardware with useless requests. In this session we’ll look…
Read MoreThanks to automation, migration between NetEye 3 and NetEye 4 can be easily performed for a lot of entities such as hosts and services. But additional elements like parent-child relationships can be missed. So we implemented a procedure for mass-migration of this information from the old platform to the new one. Solution In the NetEye…
