![]() ![]() Once integrated into the firmware, the Raspberry Pi will start for the first time with a mini operating system that will allow us to install the desired operating system. The storage is external via USB card or SD card, it is recommended 8 gigabytes at least because we can allocate 5 gigabytes for the image of any operating system and 3 gigabytes for applications and data. The RAM memory is shared with the video memory, it can bring 512 or 1024 megabytes but cannot be expanded. RaspBerry Pi are powered by a 5-volt microUSB connector or by General Purpose Input/Output (GPIO) connectors the latter will also be used to connect an RTC to maintain time and date when turned off, if necessary.ĭepending on the model, it has different input and output devices: Ethernet connector, wireless network, USB port, Bluetooth, audio output, video output, etc. They have no power source of their own, but that doesn’t mean that they don’t overheat (since every converter from alternating current to direct current produces heat by infrared rays) and that is one of the points that we will monitor in this article. If the size and efficiency is already impressive, there is also the Raspberry Zero model, even smaller, more affordable but of course with different connectors: when it comes to video it comes with miniHDMI instead of HDMI, for example ( there is no Raspberry Pi with the old VGA analog connector). What are you waiting for to get to know it better? Pandora FMS Enterprise is capable of monitoring devices, servers, applications, services or business processes. Again, if we don’t have the exact date and time, we’ll be in trouble when it comes to monitoring.ĭo you want to discover the most flexible monitoring software on the market? They always start with the date of Novemand if we are in a “hostile” environment, where they are unable to connect to any local area network, we can buy a PSTN such as this one. This architecture allows for the saving in transistors, thus resulting in a small processor size and consequent energy savings.Ī special feature of Raspberry Pi is that they do not have a real-time clock ( RTC) so they depend on the communication with the outside world through the Network Time Protocol (NTP) in order to record the date and time of their operations, which is very important when monitoring. Its Central Processing Unit (CPU) is its Reduced Instruction Set (RISC) Computer Architecture called ARM (Advanced RISC Machine), 32-bit and now 64-bit on the Raspberry Pi 3 model. It has many operating systems, a well-known one that is derived from Debian is Raspbian.There are also Pidora (based on Fedora), SUSE and Arch Linux, based on ARM (see the following point). Although its hardware is privative and made in China, its operating system and applications are completely Open Source. ![]() It does not store any personal data.In Wikipedia we can find all the details about Raspberry Pi, we would like to highlight the following: The cookie is set by the GDPR Cookie Consent plugin and is used to store whether or not user has consented to the use of cookies. ![]() The cookie is used to store the user consent for the cookies in the category "Performance".
