How To Install Cacti monitoring Debian 11 Bullseye – Guide

The project behind the Debian Linux distribution has released Debian 11 stable, codenamed “Bullseye”. It is a version that has been working for two years, one month and nine days. Debian 11 follows the 2019 release of Debian 10 “buster”. As Steven J. Vaughan-Nichols of ZDNet noted, each Debian release is a big deal, with support coming from the user community rather than a company, as in SuSE Linux Enterprise (SLES). Debian is also the main operating system for other Linux distributions such as Canonical’s Ubuntu and Raspberry Pi OS.

Debian 11 will be supported for five years and is based on the Linux kernel 5.10 series, which was released in December with long-term support of two to six years. The Debian 11 release comes with several desktop environments including Gnome 3.38, KDE Plasma 5.20, LXDE 11, LXQt 0.16, MATE 1.24 and Xfce 4.16. Version 11 ‘bullseye’ is the first Debian release to provide a Linux kernel with support for the exFAT (Extended File Allocation Table) file system and is used by default to mount exFAT file systems. In this article, we show you how to install Cacti to monitor Debian 11 Bullseye.

innodb_write_io_threads=16

innodb_io_capacity=5000

innodb_io_capacity_max=10000
