The R&D team makes extensive use of PHP unit tests in order to ensure functional correctness in all the icingaweb2 modules integrated into NetEye 4. In fact, for each icingaweb2 module we developed a PHPUnit component that allows us to perform unit tests on all PHP classes and functions present in the module. These PHP…
Read MoreUntil NetEye 4.8, customers who needed to expand the capacity of their Elasticsearch cluster running alongside their Red Hat cluster could add new standard nodes to NetEye clusters. This meant, however, that the new nodes would dedicate their resources not just to improving the capacity of the Elasticsearch cluster, but also to maintaining all services…
Read MoreFixes the NetEye Analytics health check. Now the neteye check command does not return any error even if it is run on a node where the service icingaweb2 is not active. Fixes the sidebar link, allowing to open in a new tab also submenu entries. For NetEye 4.9 we updated: icingaweb2-module-analytics to versions 1.14.4-2 icingaweb2…
Read MoreIn a previous blog post, I described how Elastic Stack fits within the High-Available cluster architecture of NetEye 4 and, in particular, how the correct configuration of the Quorum is mandatory to prevent losing your data or even developing inconsistencies. With the upgrade to NetEye 4.8, we updated Elastic Stack to the new major version…
Read MoreWithin Internet provider companies, very often we are asked to calculate the amount of Internet bandwidth in order to bill any excess use of bandwidth to each customer. We decided to make this calculation completely customizable using NetEye together with the built-in tools Icinga2, InfluxDB and Grafana. Phase 1 Using an SNMP check, we measure…
Read MoreIn the past I’ve written in this blog post about Elastic Stack and its features. Here I’d like to show you more in depth the functionality of Graph analytics. The Graph analytics features enable you to discover how items in an Elasticsearch index are related. It’s possible to explore the connections between indexed terms and…
Read MoreAs a Christmas gift, my dear friend and colleague Gabriele presented the EriZone ISMS tool, a specifically customized and configured EriZone to support the documentation of a company’s Information Security Management System based on ISO/IEC 27001. Follow this link to read his post first: https://www.neteye-blog.com/2019/12/use-erizone-to-maintain-and-improve-an-isms-based-on-iso-27001/. In this post I will give more technical details about…
Read MoreIn a series of blog posts (1, 2, 3), I described how the R&D Team development process has changed to meet new requirements, to improve delivery time and quality, and to increase adaptation. As mentioned, the R&D Team development activities are planned and prioritized for each NetEye release. The main problem of such an approach…
Read MoreAlmost 2 years ago, we first announced the start of our new NetEye 4 product. With NetEye 4 we started to build our monitoring solution on top of the popular Icinga2 and Icingaweb2 framework. Having been in the position of implementing some of the first projects based on NetEye 4, I recognized the need for…
Read MoreRegularly updating operating systems is now an essential task. And the operating system at the base of NetEye (CentOS 7) must be regularly updated. But I still find many customers who for lack of time forget these updates and ask me if it’s possible to get an automatic report of them. And here I found…
Read MoreThis year my colleague Mirko and I had among our annual goals the use of EriZone to support ISO 27001. The project was not highly detailed, so therefore we felt free to interpret it the way we thought would be most useful for a medium-sized company. Obviously we needed to know exactly what ISO 27001…
Read MoreThe Problem If you’re trying to monitor a Microsoft Cluster, you’ll surely want to monitor the disk space of a single cluster service. In this case there’s a problem with Icinga2 Agent: you can’t use it with more than one IP address. So you can’t simultaneously monitor the resources of the “physical” host and a…
Read MoreToday I’ll present you a hidden gem in EriZone and OTRS: With a few clicks, your favorite browser’s search bar will be able to search for ticket numbers or full text in EriZone. The browsers’ search and address bar fields come with some predefined search engines, but can also be extended with your own searches….
Read MoreSometimes you just need to temporarily grant access to a user to copy some files to your server. But no user should have access to the shell. For sftp this is quite simple (see below), but for scp it’s not that trivial. Also, you probably want to set the user up in a directory with…
Read MoreThe NetEye 4.9 release introduced a brand new module called Shutdown Manager. My aim in this blog is not to explain how the Shutdown Manager works, but instead to introduce the logic behind it in order to better explain when you should use it, and how you can deliver a configuration file during Icingaweb2 Director…
