Smoke or Gas Sensor with Raspberry Pi

If we want to analyze some type of gas with a Raspberry Pi, we can make it very simple with MQ sensors, we will only need to know in any case which sensor to obtain depending on the gases to be analyzed and that's it, We will see in this post how to connect it and get the values. As usual, at the end we will save the data obtained in a MySQL database to visualize it from Grafana!

Monitoring a QNAP NAS

In this post, we'll look at how to monitor a QNAP NAS or SAN that we have in our organization, we will do it only through SNMP and we will see everything we can get! Thanks to Centreon it will be quick and easy to have everything under control, from hard drives to any chassis sensor or RAID status! Nothing, We get a couple of necessary scripts first and that's it! Then sew and sing!

What's New in Nakivo 7.4

I wanted to bring you the new features of the new version of Nakivo, We already have the more than mature version 7.4 by Nakivo Backup & Replication, It will surprise us with everything it offers! Remember that Nakivo is a low-cost backup and replication solution for our virtual environments, a player that is becoming more and more consolidated every day!

Measuring atmospheric pressure with Raspberry Pi

If we want to know and monitor atmospheric pressure in a cheap way… How could you not… This is your document! We can do it quickly with a Raspberry Pi and a sensor that barely goes beyond the 2 Euros! In this post we will see all the steps you will need to achieve it, Also as always… we will store the measurements in a MySQL database and then we will visualize the values with beautiful graphs thanks to Grafana!

Integrating FreePBX with Movistar's fiber optics

If you have Movistar fibre optics in your home or company, maybe you didn't know that you can use it to connect through a SIP softphone or an IP PBX to make and receive calls from your phone line. Interesting for any company, Or what? And for home for home automation issues that are not even painted 🙂 In this post we will see all the necessary steps to make it fully functional!

FreePBX Installation and Basic Configuration

In this document we will look at the installation of an IP PBX using FreePBX, the distribution that comes with Asterisk installed and allows us to configure our PBX in a simpler and more intuitive way through a GUI. This first document only consists of a basic installation and configuration that we will use in future documents to do very cool things integrating it with a Raspberry Pi.

Monitoring a Linux computer with Centreon, example with a Raspberry Pi + Temperature of your CPU

I'm going to put this post because of all the requests I've been receiving on how to monitor a Linux server. As obviously depends on the distribution, today we have an example with a Debian and more specifically we will see it on a Raspberry Pi that carries Raspbian. We'll monitor basic metrics like CPU, RAM, Swap Memory, Disks, Network Traffic, Uptime… And in the end we will see something very interesting!
