You can only monitor systems that you know!
GLPI is a very successful open source ITSM solution, the project follows a modular approach and can therefore be extended by many very useful plugins. And yes … GLPI is mainly “French” 😊 !
In this very short introduction, I’ll will give you a rapid overview how to:

– automate your IT inventory to manage pc’s, servers, vm’s, vmware, …
– add printers and network components via “snmp”
– add special assets like databases, appliances, URL’s, lines, racks, datacenters…
– add additional information’s to all this components
– add people from your LDAP / AD
– add plugins to GLPI
– build reports
– import / export your data
– handle tickets, problems, changes, or projects

In my second presentation “Monitoring @ G&D ” I will later show you how we’ve automated our monitoring with the help of GLPI, some db view’s and python scripts.

All monitoring systems are a preferred target for malicious intruders because they have access to many interesting things in your network. And they store many many passwords for websites, SNMP credentials for network devices, etc… And usually they are stored in plain text and they
are not hard to find either.
So to make things a bit harder for black hats, Naemon introduces the Vault API for secure
storage of passwords and other things you won’t like to store in plain text.
This talk introduces the API and gives some examples of how to use it.

Monitoring oceans, agricultural lands, forests, and cities using satellite imagery is a key area of ongoing research. Particularly, the rise of open-source large-scale Earth observation datasets for this purpose facilitates the development of machine learning models like artificial neural networks for assessment of landscapes. In this talk, we discuss how we can train deep learning models and especially harness multitemporal data and change detection to detect damage after natural disasters, inform sustainable agriculture, monitor wildlife, and more.

Optimizing MySQL performance and troubleshooting MySQL problems are two of the most critical and challenging tasks for MySQL DBA’s. The databases powering your applications need to be able to handle changing traffic workloads while remaining responsive and stable so that you can deliver an excellent user experience. Further, DBA’s are also expected to find cost-efficient means of solving these issues. In this presentation, we will demonstrate the advanced options of PMM version 2 that enables you to solve these challenges, which is built on free and open-source software. We will look at specific, common MySQL problems and review them.

Thola is a new open source tool for reading, monitoring and provisioning network devices written in Go. This talk will inform about the current state of development as well as planned features, including reading out inventory, configuring network devices, support for other monitoring systems like Prometheus and many more. It serves as a unified interface for communication with network devices and features a check mode which complies with the monitoring plugins development guidelines and is therefore compatible with Nagios, Icinga, Zabbix, Checkmk, etc.

The very first public OpenNMS code was posted on Sourceforge in March of 2000 (by comparison, NetSaint, the precursor to Nagios, posted its first code in January of 2000). OpenNMS turned 20 years old last year, but due to the spread of COVID-19 we did not do much to celebrate. But 2021 is a new year, and this talk will cover the history of the OpenNMS open source project over the last 20 years. It is an interesting story, starting with the company that began the project and why they decided to abandon it. How it was picked up by an individual who managed to grow the community until they could form a new company to support it. What happens when another company steals your software project and tries to make a commercial product and how do you handle growth and then an acquisition. The talk will also cover how OpenNMS has grown from a monitoring solution based mainly on synthetic transactions to an observability platform used by some of the world’s largest companies, and where it plans to go next. If you are wondering how to build a business around an open source project, this talk will not have all the answers, but perhaps by going over the history of OpenNMS it will provide some clues.

At G&D we have one ICINGA system specialized in monitoring our complex SAP environment. To keep ICINGA “up to date” the “Config Build” is automated with the help of GLPI.
All technical information’s are collected by GLPI’s “Fusioninventory” plugin, some custom ICINGA fields are added with the “Fields” plugin to our Server- , Database- and SAP Objects.
To build the ICINGA configuration we use various database views (GLPI’s mysql) and some python scripts … but it would be possible to use the “Icinga Director” as well.
Finally, we are informed if the monitoring configuration would change due to system changes detected by GLPI. This means that we can adjust our monitoring fully- or semi-automatically.
